A stove made of two gas cylinders. How to make a potbelly stove from a gas cylinder with your own hands? Jet units and other mobile structures

When cold weather sets in, the issue of insulation becomes relevant. It is especially important for rooms that you visit from time to time. This includes garages, workshops and utility rooms where it would be impractical to install a stationary system. In some cases, this is completely impossible, but if you are unable to do without heating, then you can make a stove from a gas cylinder with your own hands.

It is recommended to use one of two options, the first involves creating a system using electricity, while the second is using solid fuel. The latter include a potbelly stove, which even an inexperienced home craftsman can create. The main element of this design will be the housing; it will be necessary to make two holes through which fuel will be placed inside. The system must have a vent and a chimney. The last element is quite often connected to the compartment where the ash collects. To make cleaning the oven easier, another door will need to be installed in this place.

If you are making a stove from a gas cylinder with your own hands, then the chimney should not be laid along a short path, as most of the heat will evaporate outside. This approach cannot be called rational, so experts advise installing a broken-shaped pipe. This way you can increase the efficiency of the heating device. You can use coal, firewood, old clothes and even household garbage as fuel. The potbelly stove also attracts craftsmen with its simplicity and versatility, because with its help you can not only heat rooms, but also cook food.

Preparation for work

If you are making a stove from a gas cylinder with your own hands, you must first prepare the container for use. This procedure must be carried out without fail, otherwise the gas may explode from the impact of a spark that occurs during the cutting process. The technician must unscrew the valve and allow the remaining gas to escape. The container should then be turned over and the condensate drained. Its smell cannot be called pleasant, so it is worth collecting the remains in a container.

The cylinder is installed vertically and filled with water, this will allow the remaining gas inside to be removed, after which the container is turned over on its side, which will allow the liquid to be drained, now the cylinder can begin to be cut. Before starting work, it is important to determine how the potbelly stove will be located: horizontally or vertically.

The first option for making a furnace

A do-it-yourself wood-burning stove made from a gas cylinder can be made on the basis of a horizontal structure. Initially, you will need to cut off the upper part of the cylinder, and then install it inside. It should be made from reinforcement, arranging the elements like a snake. Installation of the grate is accompanied by welding work, after which you can work on the front part of the stove. On a sheet of steel you need to mark the outline of a circle, the diameter of which will be equal to the outer contour of the cylinder. Next, the part is cut out, and two rectangular holes are marked inside the circle. The first is necessary for supplying fuel, and the second will act as a blower.

Main stage

If you make a stove from a gas cylinder with your own hands, you can see the photo in the article. Using a grinder or chisel, you will need to cut out the intended holes, which were discussed above. The curtains should be attached to the finished lid by welding and doors should be installed on them. The latter must be sealed with asbestos-cement cord. At this point we can assume that the front part of the oven is ready, we can move on to working on the back part. This stage involves the arrangement of a chimney, for which you need to make a hole with a size equal to the diameter of the pipe. A chimney of the desired shape is installed in it, which should be made from a thick-walled pipe.

Making a vertical furnace

If you are making a stove from a gas cylinder with your own hands, step-by-step instructions will be useful to you. If you need to perform a vertical structure, you can use one of two methods. The first involves an impressive amount of work, they are associated with cutting, but the installation stage will be accompanied by fewer difficulties. If you decide to choose this method, then using a grinder you need to remove the top of the container. The second method will save time, electrodes and effort, but it cannot be called convenient. In this case, the top must be furnished in place.

Whichever method you choose, you will need to cut a large firebox hole in the front. At the bottom there is a smaller hole for cleaning and blowing. When a long-burning stove is made from a gas cylinder with your own hands, the same technology is used. The holes can have arbitrary sizes. At the next stage, the gratings are prepared for installation work; in the first case, these elements are lowered through the top, but the second technology does not provide the opportunity to install the grates in this way; they will need to be inserted from below, which is extremely inconvenient.

Ensuring tightness and installing the chimney

If it is made from a gas cylinder, then at the next stage you need to install the curtains, and then weld them to the holes. The door is covered with asbestos-cement cord, which will guarantee excellent tightness. We should not forget that the holes for the chimney still need to be made. Through the hole located in the top cover, exhaust gases will be removed and oxygen will be supplied. Its dimensions must correspond to the diameter of the pipe. You can also provide side smoke exhaust. In this case, you need to work on the side of the body. Experts in some cases advise to equip the knee, but you can draw the conclusion quite directly. If the cylinder has lost its upper part, then the chimney can be installed on top.

Making a furnace for mining

You can easily make a stove from a gas cylinder during testing with your own hands. Its design is not complicated. You can also use sheet metal; to do this, you should make two combustion chambers, to one of which legs are attached. The two compartments are connected by a pipe with holes, and this element is installed on the upper chamber. All these works require the use of a welding machine and the presence of certain skills from the master. If you want to get by with less time, you can use a gas cylinder. It has thick walls and will ensure fire safety. The air supply to one of the chambers must be made adjustable; for this, a damper is installed, which can be opened slightly if necessary. The chamber where the used oil will be supplied should be dismountable, so you can clean it. The chimney pipe is located vertically; there should be no inclined or horizontal sections. For good draft, the chimney must be selected so that its length is four meters or more.

Work technology

When a stove is made from a gas cylinder during processing, it is necessary to cut off the lower and upper parts of the container; the resulting halves will form the basis of a collapsible combustion chamber. The lower part must be equipped with metal legs, and a hole is made in the upper part into which a pipe with an adjusting plate is installed. There should be a hole in the central part to which a pipe connecting the two compartments is welded. Air holes must be made in the connecting element. The middle part of the container will be used to make a secondary combustion chamber, which is attached to the connecting pipe. The final stage will be the manufacture and installation of the chimney pipe, which can be problematic due to the impressive length of the component.

If you are making a stove from a gas cylinder with your own hands, then you should choose the dimensions yourself; these parameters are not so important for the reason that the operation of the structure can be easily adjusted. In rare cases, garages and workshops, as well as utility rooms, have perfectly flat floors. In order to install the stove correctly and ensure its fire safety, it is necessary to make the legs adjustable in height.

If you notice that oil is splashing out of the combustion chamber, then you need to stop the operation of the device, wait until the surfaces have completely cooled and drain the fuel. There should be no more than 2/3 of it in the compartment. If the waste starts to boil, it is necessary to reduce the air supply using the adjusting damper. For sufficiently intense draft, it is necessary to periodically clean the tank and chimney. The upper part of the product can be removed from soot by tapping.

Conclusion

The production and operation of such a heating device is very cheap. This is also due to the fact that used oil can be easily purchased or taken almost free of charge at a service station. If you are a car enthusiast, then you can have a special container for oil in which you will collect the waste obtained during the warm season.

The simple, unpretentious design of the potbelly stove made it a hit among heating devices that can be built at home. This popularity is due to several factors, one of which is the undemanding nature of materials. A good, productive stove can be made from metal, which can always be found from a zealous owner - pieces of reinforcement, strips of sheet steel, remnants of metal pipes and angles, and even from parts from various machines and mechanisms. Often, a ready-made container is used as a housing - a piece of large-diameter pipe, a barrel for fuel and lubricants, or a container for household propane-butane. We’ll tell you in more detail about the advantages of the last option and how to make a potbelly stove from a gas cylinder with your own hands.

The secrets of the popularity of a potbelly stove from a cylinder

This stylish potbelly stove can be built from a regular gas cylinder

Potbelly stoves are simple, small-sized stoves designed for heating small rooms that, for some reason, cannot be heated by a full-fledged engineering system. Most often, units of this type are made of metal and are used in garages, sheds, country houses, greenhouses and change houses. Sometimes potbelly stoves are installed for temporary heating of residential premises, and with minor modifications they are left as the main source of heat.

Making a stove from a gas cylinder has a lot of positive aspects:

the thickness of the walls of the container is more than 3 mm, which is quite enough to ensure the rigidity and strength of the structure;

Vessels for storing gases are made of high-alloy steels that successfully resist corrosion. In addition, sufficiently thick and high-quality metal guarantees that the walls of the potbelly stove will not burn out for a long time;

minimal modifications will be required. Since there is no need to manufacture the furnace body, the time for building the heating device is reduced;

Even if you buy a container for household gas, its cost on the secondary market is only a few hundred rubles. Most often, you can get a cylinder completely free of charge by asking around among your acquaintances and friends;

from the point of view of heating engineering, the cylindrical shape of the firebox is optimal, therefore a potbelly stove made from a vessel for household gas is economical and highly productive;

the existence of several structures, among which are horizontal and vertical units of direct or pyrolysis combustion;

very fast heating of the room both due to radiation and convection.

The disadvantages of a heat generator built using a gas cylinder are inherent in all potbelly stoves. Firstly, the walls of the heating device become red hot, which in no way contributes to the safety of the unit. Secondly, it is impossible to guess the exact amount of firewood in order to somehow regulate the heating temperature. Thirdly, the extremely low heat capacity of such a structure. The potbelly stove will provide heat exactly until the wood burns out. After this, it will instantly cool down.

Most often, 50-liter propane cylinders are used to make potbelly stoves.

To increase the heat-storing capacity of the furnace body, the unit is often encased in brick or stone masonry, a water jacket and other methods of energy storage are used.

I would also like to note not a minus, but rather a feature associated with the fact that gas cylinders are painted with ordinary enamel. At high temperatures, the paint will burn out, filling the room with toxic smoke. To eliminate the possibility of poisoning, you will have to remove the top coating mechanically or conduct the first two or three fires in an open space.

Design features and principle of operation

Like any other direct combustion solid fuel stove, the unit, made from a gas cylinder, consists of several parts:

firebox combined with the body;

grate;

blower chamber;

chimney.

The blower is located at the bottom of the stove and is a small chamber (essentially a channel) necessary to supply oxygen to the combustion zone. To regulate the amount of air, monitor the process and remove ashes, the ash pan is equipped with a door.

Simple design is one of the components of the success of cylindrical potbelly stoves

In the middle part of the furnace there is a combustion chamber, which is separated from the ash pan by a grate. Being the main module of the heating device, the firebox simultaneously plays the role of a loading compartment and a heat exchanger. Like the vent, the firebox is equipped with a door through which firewood is placed into the potbelly stove and ash is removed.

The chimney is a channel necessary to remove combustion products from the working area. A damper must be installed in the chimney, which is closed after the wood burns out. This prevents heat from escaping from the room when the stove is not in use.

The operation of a heat generator from a gas cylinder is not difficult. After the firewood is placed on the grate, they are set on fire and the combustion chamber door is closed. The blower must be open at this time - air passes through it to the fuel. The intensity of combustion is controlled by closing or opening the bottom door. Heated gases are removed through the chimney.

To increase the efficiency of heat exchange, the potbelly stove is equipped with additional elements that allow the residual heat of the flue gases to be removed. To do this, an air heat exchanger or a water jacket is installed on the chimney. Often the modification consists of lengthening the part of the chimney that is located in the room.

Preparatory activities

If you think through everything and prepare it in advance, then during the work you will be able to avoid mistakes and reduce time costs. First of all, you will need to remove the remaining gas from the cylinder, collect the necessary tools and purchase the missing materials. A detailed drawing or sketch of the heating device will also help in the work.

What kind of cylinder is needed and how to prepare it for work

First of all, we note that only all-metal cylinders for household propane-butane are suitable for making a potbelly stove, including those used to equip LPG in trucks or cars. The best preparation can be considered a 50-liter vessel, which can be found in most private households. Its height of 850 mm and diameter of 300 mm is enough to burn all types of fuel, from firewood or sawdust to used motor oil.

A good potbelly stove can be built from a 27-liter propane cylinder if you use a horizontal design of the unit and retrofit it with an ash chamber. Its small size allows this unit to be used as a mobile structure.

Since even an empty cylinder may contain gas residues, condensate or its vapor, it can be dangerous to carry out any work with it without careful preparation of the container - any spark can lead to an explosion.

The water will displace the remaining gas from the cylinder, after which you can begin plumbing work without fear

To completely remove propane or its derivatives, use a proven method:

Open the valve and release the remaining gas from the cylinder.

Turn the container upside down and pour out the condensate.

Using a gas wrench or an adjustable wrench, remove the valve.

Place the vessel vertically and use a hose to completely fill it with water. The liquid will completely displace the remaining gas and make the preparation for the potbelly stove safe.

After the water has been drained, you can carry out any plumbing work with the cylinder - cutting, drilling, cooking, etc.

Since both gas and condensate are explosive substances, and in addition, have a strong, unpleasant odor, work must be carried out in the open air, away from open flame sources.

The valve from the cylinder can be unscrewed using an adjustable wrench

What you need to avoid being distracted by small things

Before getting started, you need to prepare the following tools:

welding inverter or transformer designed for currents up to 200 A;

a manual grinder, or, as it is called in our country, an angle grinder, designed for the use of discs with a diameter of up to 180 mm;

stripping and cutting discs for metal work;

grinder attachment for cleaning metal from rust;

electrodes with a diameter of 3–4 mm;

welder's hammer;

drill with a set of drills for steel;

chisel;

hammer;

pliers;

tape measure, metal ruler and square;

marker and core.

In addition to one or two gas cylinders, to build a potbelly stove you will need:

A potbelly stove made from a cylinder can be equipped with factory cast iron doors

sheet steel more than 3 mm thick;

chimney pipe with a diameter of 100 mm;

chimney elbow 90° or 2x45°;

cast iron doors;

grate bars or steel reinforcement with a diameter of 20 mm to replace them;

hinges for hanging the door;

metal corners with a shelf measuring at least 30 mm.

If you are a supporter of aesthetics in any of its manifestations, then, in addition to everything else, prepare a solvent, primer and paint. A painted potbelly stove will look much better, and the final finishing will give the unit a complete look. Of course, these materials must be designed for use in high temperature environments.

Which design to choose for your project

Despite all the variety of stoves that can be built from a regular gas cylinder, existing designs can be reduced to three main types:

horizontal;

vertical;

combined.

A horizontal potbelly stove is easier to manufacture and, according to the owners, has greater heat transfer (which, in principle, is not far from the truth, given the slightly enlarged fuel chamber). At the same time, it occupies a large area, which in some cases is unacceptable. Horizontal units are good where there is room to turn around - in spacious workshops, warehouses, greenhouses, etc.

The horizontal position of the cylinder is more advantageous from the point of view of thermophysics

The vertical heating device takes up much less space and has an ideal configuration for installation in a corner. For installation in garages and small spaces, home craftsmen choose this particular design, although it is more difficult to manufacture. The difficulties arise from the fact that to install the grate you have to weld in a limited space, and this is not very convenient. At the same time, there is a method when, to install the grate, the cylinder is cut into two parts, and then welded again.

Vertical stove - one of the most compact heating devices

Combined potbelly stoves are made from two or more cylinders, one of which acts as a firebox, and the other as a heat exchanger. In fact, such a heating device is the same horizontal structure, but since its chambers are made of separate vessels, we still classify such structures as a separate subspecies. Combined-type stoves are the most economical and thermally efficient heating devices, but they cannot be called ideal, given their large dimensions and increased labor costs.

The combined heating device has increased efficiency

Below we have presented drawings and diagrams that can help you in your work or in designing your own structure.

Making a potbelly stove from a propane cylinder with your own hands

The popularity of horizontal and vertical designs is so great that it is difficult to choose one or the other as the ideal option. Therefore, we will talk about the features of the construction of both heating devices.

How to make a vertical unit: step-by-step description of processes

The propane cylinder is placed on the floor, after which the cutout locations for the oven doors are marked. Special precision is not needed here - the dimensions are determined based on ease of use and personal preferences. It is best to draw lines with a marker, going around the container with a tape measure. Most often, the blower is made 10–15 cm high, departing from the bottom of the cylinder at least 5 cm. The firebox door should be larger - at least 25 cm in height. The width of both openings is the same, from 25 to 35 cm. As for the distance between the doors, it is made at least 10 cm - in this case, the necessary gap will be provided for installing the grate.

Correct marking is the key to successful stove operation

Along the line that divides the distance between the combustion and blower doors into two parts, cut the cylinder in half.

To facilitate the installation of grate bars, it is better to cut the cylinder in half

The short, lower part is installed vertically, after which grate bars are welded into its upper opening. They use pieces of reinforcement Ø20 mm of the required length. The gap between the individual grille elements should be from 5 to 10 mm, depending on the type of fuel used.

Installation of grate

The halves of the cylinder are combined with each other to their original state and welded with a continuous seam.

Using a grinder, openings for the firebox and vent are made in the side wall of the vessel. Since the cut out parts will be used as doors in the future, the work must be done as carefully as possible. To simplify your task, first cut the vertical grooves, after which the hinges are welded. Only after this the grinder is passed along the entire perimeter of the loading and blower window. This method greatly simplifies the installation process - after cutting, the doors will be securely held in place. It is also important that you will not need to set gaps, which are quite problematic to do without an assistant.

It is better to install the hinges before the door is separated from the body

Instead of factory hinges, you can use a couple of links of a powerful drive chain from agricultural machinery for a homemade design.

The role of loops will be successfully played by the links of a large chain

To prevent the doors from falling inward, stops are welded to the back of the openings. They can be cut from a steel strip with a thickness of at least 3 mm. By the way, such a strip can completely scald the entire opening - it will eliminate the gap through which the stove can smoke into the room.

Stops for fixing the door in the desired position

Handles are bent from a metal rod 8–10 mm thick and welded to the doors.

Bolts are made from a steel strip and the same rod, which will prevent the spontaneous opening of the blower and furnace doors.

The valve is cut off from the top of the cylinder. This should result in a hole with a diameter of 105 mm.

A piece of steel pipe 15–20 cm long is cut lengthwise and then unbent, expanding the gap to 10 mm. The resulting gap must be welded in such a way as to obtain a workpiece with a diameter of at least 105 mm.

The resulting segment is welded into the upper part of the cylinder - it will play the role of an outlet pipe (collar) into which the stove pipe will be inserted. In some cases, the smoke channel exits from the side. The horizontal section of the chimney allows you to slightly reduce the speed of the outgoing gases and increase heat transfer. The hole for the valve must be welded.

A vertical chimney is much easier to install, but the side exit of the chimney will increase the thermal efficiency of the potbelly stove

Since stoves of this type often use low-quality fuel, professional stove makers recommend making the stove pipe composite. The detachable design makes it easy to disassemble the chimney to clean it from soot and other deposits.

Depending on the design of the chimney, it is made straight or curved. In the latter case, use a knee with the required degree of bending. To ensure sufficient draft, the length of the chimney must be at least 4 m, and its upper cut must be located above the roof.

At a distance of 5–10 cm from the junction with the pipe, a valve (gate) is installed on the chimney. To do this, a circle is cut out of sheet metal, the diameter of which corresponds to the internal section of the chimney, and a through drilling of Ø8 mm is made perpendicular to the chimney. After this, an L-shaped steel rod of appropriate thickness is installed in the hole, to which the damper is welded. To prevent its spontaneous rotation, install a lock of any type.

A cutout in the damper increases the safety of the unit, since it eliminates the possibility of smoke due to spontaneous closing

If necessary, the finished product is painted, after which it is installed in place, a chimney is attached and a test fire is carried out.

Instructions for making a horizontal stove-stove with photos step by step

The valve is unscrewed from the cylinder, after which the hole is welded.

The support shoe is removed from the bottom of the cylinder, and then a square loading window is cut through the spherical end. It is best to do this in the same way as when making a vertical potbelly stove, that is, by first installing the hinges. In this case, the cut door will not have to be exposed before installation.

The design can be simplified by eliminating the grate from it. In this case, many Ø10 mm drillings are made in the bottom of the stove, through which oxygen will flow to the firewood.

On the grate side, an ash pan up to 10 cm high is mounted on the cylinder. For this, you can use a section of a channel of a suitable size.

Ash pit installation

Legs are welded to the cylinder, which can be made from any suitable pieces of pipes, angles or fittings.

In the upper part of the cylinder, at a distance of 20–25 cm from the closed end, a hole with a diameter of 105–110 mm is cut, onto which a collar is mounted (from a metal strip or a pre-fabricated pipe).

It is best to cut a round hole using a diamond bit or a gas (plasma) cutter. If this is not possible, then many Ø6–8 mm drillings are made along the contour of the future chimney, after which the window is cut out with a chisel.

A stove pipe equipped with a damper is installed on the potbelly stove. That's it - the heating unit is ready for work!

This is what the final unit should look like:

Recommendations for choosing a location and operating a heating device

A potbelly stove is such a compact heating device that it can be placed in almost any room, the main thing is that the chimney can be taken outside. It must be remembered that the efficiency of the device and the safety of its operation depend on the correct choice of location for installing the stove. Therefore, we recommend taking the advice of professional stove makers.

For maximum heat transfer, it is best to install the potbelly stove in the corner of the room farthest from the door.

The installation site of the stove is covered with a metal sheet that is 20 cm greater than the overall width of the heating device and at least 60 cm greater than its length.

The potbelly stove must not be installed under shelves or near places where flammable and explosive materials are stored.

The room is equipped with effective supply and exhaust ventilation.

When installing potbelly stoves, be sure to maintain the gaps between the walls of the heating device and the combustible structures of the room. For fire safety purposes, the latter are protected with special screens with ventilated gaps.

Once the safety of the heating device has been ensured, you can proceed to the firebox. For those who are encountering a potbelly stove for the first time, let us consider the process of putting the stove into operation in more detail.

The installation location of the stove must comply with safety standards

First, flammable fuels are loaded into the firebox - paper, cardboard, straw or rags soaked in kerosene. A few chips and finely chopped firewood are placed on top, and large logs are placed on top of them. Firewood can be placed in any way - horizontal rows, cage, cone, etc. After this, the bottom layer of fuel is set on fire and closed, leaving the ash door completely open. The vent is covered only when the stove reaches operating mode, as evidenced by a characteristic hum. Correct adjustment of the air supply is indicated by a slight noise, a “whisper” of the furnace - with such a load, the unit provides an optimal balance between efficiency and productivity.

You can stir the firewood only when it is at least half burning. Otherwise, normal combustion may be disrupted and the unit will switch to smoke generator mode. Coal is poured into the stove when the wood has burned through 70–75%, having previously poked through the heat with a poker.

As you can see, a potbelly stove made from a gas cylinder is a good option for repeating at home. Its production will require a minimum of effort and time. The presence of several modifications allows you to choose the most suitable design for yourself, and unpretentiousness to materials will make it possible to get a stove almost free of charge. Finally, I would like to remind you of the need to carefully handle the gas cylinder and carry out welding work - your health and safety depend on it.

In winter, potbelly stoves are often used. There are several ways to create a stove from a gas cylinder, using various materials and means.

The horizontal device is used for cooking and heating small spaces. A vertical potbelly stove is installed in garages, utility rooms and small buildings.

Selection of cylinder and materials

The furnace body is made from an old empty gas cylinder. For effective operation and high heat transfer of the structure, you need to decide on the size of the container. A small room can be heated using a five-liter cylinder. Small stoves with low power are constructed from containers ranging in size from 12 to 30 liters.

A gas cylinder stove is an excellent solution for heating your garage

The industrial one (40 l volume) has thick walls, and the diameter of the inner surface is too small to accommodate a sufficient amount of fuel. The best option is a 50-liter propane container with a height of 85 cm and a diameter of 30 cm.

The cylinder is carefully prepared before work:

• unscrew the valve and leave the container for a day to allow the remaining gas to escape;
• then turn it over and drain the condensate into an unnecessary container;
• the balloon is filled with water and kept for several hours;
• pour out the water.

The cylinder for making a furnace must be thoroughly cleaned

The remaining propane must be removed from the container, otherwise the cylinder may explode during welding. Additionally, you need to prepare some materials and tools:

• chimney pipe;
• steel sheets with a thickness of at least 3 mm;
• reinforcing bars;
• metal corners;
• pliers, chisel and hammer;
• welding machine;
• Sander;
• drill with drill bits.

Doors for the furnace are made from steel, and fittings are necessary to create grates. If it is not possible to make these parts for the stove from a gas cylinder with your own hands, then you can buy ready-made elements in specialized stores.

In this video, learn more about the potbelly stove from a cylinder:

Main types of oven

A vertical stove is made more often, as it takes up little space and has a neat appearance.

The horizontal design is valued due to the large cooking surface area. The dimensions of the ash pan and the hole for storing firewood in any device are 10x20 and 20x30 cm, respectively. Their markings are applied both to the drawings and to the cylinder itself - this makes it easier to cut out. The location of the holes is chosen arbitrarily, depending on the type of stove.

With the help of such a stove you can heat the room and even cook food outside

The chimney is made from a steel pipe, cutting it into different sections and welding them together. Additionally, you need to insulate it with mineral wool and foil. You can use the finished potbelly stove indoors or outdoors. If the stove is used for cooking outdoors, then it is enough to attach a low pipe for the smoke to escape.

Vertical stove

To create a vertical stove from a propane cylinder, it is placed vertically. It is necessary to cut off the neck, use a marker to draw the markings of the ash pan, chimney and firebox. The holes are cut with a grinder or cutter. Reinforcing bars are cut into identical pieces, forming grate bars. They are welded to the body in parallel rows or in a snake. Hinges for doors are attached, doors are cut out of steel sheet or cast iron. A sliding mechanism or latches are welded to them.

A hob is necessary if food will be cooked or water will be heated on the stove. To create it, you need to cut out a metal part of suitable size and weld it to the top of the cylinder. After this, all joints and seams are checked for tightness and strength, cleaned and sanded.

The vertical oven is more popular because it takes up less space

The hole for the chimney should be located at the top of the cylinder or on the side, sometimes the pipe passes through the central opening. In the side part, the elbow is first attached, then the chimney itself. Smoke and combustion products come out through the pipe. A metal stand or strong legs are attached to the bottom of the cylinder. Additionally, you can prepare the foundation for the potbelly stove.

Horizontal design

The first step is to create a strong stand. It is made of metal, the legs are welded, and then the body of the finished stove. A marker on the cylinder marks the location of the blower, chimney and fuel holes. The openings are cut with a chisel, grinder or cutter. Using a drill, holes are drilled in the lower part of the body. An ash pan is attached to the top; it is made of strong, heat-resistant metal. A damper is welded to the opening, which will serve as a blower.

The door is prepared from the cut out part of the cylinder. It must be scalded and attached to the body using loops. Although you can make a cast iron door with a latch and weld it. The chimney should exit from the top rear of the stove. A steel sheet is laid and secured on top of the body to create a flat cooking surface.

A horizontal stove will require more space - this is its main disadvantage

You can buy ready-made burners in the store, cut a hole in the steel for them and secure them. This way you can make a stove from a horizontal gas cylinder, but it takes up a lot of space.

When making a stove from a cylinder with your own hands, you need to take into account several nuances. It is necessary to adhere to the basic recommendations and rules of work:

• the chimney should consist of broken sections, since all the heat will quickly escape through a short pipe;
• fuel can be anything - coal, firewood, wood waste, household waste;
• the efficiency increases with increasing chimney length, but straight and downward sections must be avoided;
• heat transfer increases if another container is placed inside the main body, but of a smaller size. This way you can increase draft and prevent smoke from entering the room.

At home, you can make a stove from a gas cylinder for heating small spaces. This is an economical design that allows you to heat a small country house or quickly prepare food in a few hours.

More information about a wood-burning stove made from a gas cylinder:

With the onset of cold weather, many are thinking about how to better insulate their home and make it more comfortable for wintering. In addition to the basic thermal insulation work with walls, roof and floor, you can create an additional heat source - a stove from a gas cylinder. The practice of constructing such devices goes back decades, and during this time many schemes and methods have been invented for creating functional stoves from simple gas cylinders. In this article we will talk about the most popular of them.

Homemade stoves made from gas cylinders are significantly more economical and efficient than similar designs made from other available materials. This is explained by the very shape of the cylinder - it is ideal for pyrolysis processes. The quality of the stove depends on its firebox. As practice shows, the ideal shape for the combustion chamber is a sphere. Plus, it must have two holes: for oxygen to enter and gases and smoke to escape into the chimney. The oblong cylinder of the gas cylinder makes it possible to realize all the necessary requirements for a perfect firebox without significant deformations. Types of furnaces An old cylinder, aimlessly gathering dust for years somewhere in a barn, can serve as the basis for creating a stove for your home. And the best thing is that the matter is not limited to any one variety - you can choose a design to suit your taste. Each type of gas cylinder stove differs in the degree of complexity of assembly, efficiency and operating principle. So, the most popular option is the familiar potbelly stove. We will talk about its advantages, disadvantages and installation method a little later. The waste oil furnace is also popular because the cost of used oil is very low and allows you to save on fuel. You can build a rocket stove from a gas cylinder, but for beginners it is better to start with something simpler, since such a design is very complex and requires a lot of time and labor. The photo below shows a diagram of such a rocket stove and how it looks in the interior. The basic rule when assembling a stove from a gas cylinder with your own hands is to keep financial investments to a minimum. It is also important to ensure the convenience and safety of using the structure, especially if it is located in a residential building. Cylinder selection Not just any gas cylinder is suitable for making a stove. First of all, it must be all-metal, since explosion-proof composite products are not heat resistant. The capacity of the container also plays a role - a small 5-liter flask is unlikely to make an effective stove. Such a cylinder can only be used to create a fuel reservoir for a liquid fuel stove. Cylinders with a volume of 12 l and 27 l will produce furnaces with a power of 2-3 kW and 5-7 kW, respectively. But the best option for building a high-quality stove capable of heating a small private house is a 50-liter cylinder 30 cm in diameter and 85 cm in height. Its volume is quite enough for virtually waste-free combustion of any type of fuel. In addition, such cylinders are still in demand and a working product can be purchased quite inexpensively. The furnace assembly technologies described below involve the use of just such cylinders. Helpful advice: If you come across a cylinder with a valve, then it is better to choose it for the stove rather than a product with a valve. Using the valve, it is convenient to regulate the combustion power of the furnace, supplying more or less oxygen to the combustion chamber. It is also worth mentioning cylinders for industrial gases with a volume of 40 liters. It is better not to use them to create stoves, as they are too narrow, heavy and bulky. Some people make camping stoves from small industrial cylinders of 2-10 liters, but they are only suitable if you go camping by car - the products weigh too much. Potbelly stove from a cylinder As we have already said, the most popular stove that can be assembled from a cylinder is the potbelly stove. A small 12 liter or 27 liter cylinder is suitable for its manufacture, but you can also take a 50 liter container if you plan to heat a country house. A potbelly stove is suitable for heating a small room, for example, a country house, garage or workshop. If you have built a new country house, but did not have time to install heating communications before the cold weather, a potbelly stove will be your salvation for the winter. The construction of a potbelly stove made from a cylinder is quite simple: a firebox with a grate, a vent and a chimney. You can place it in any room from which it is convenient to bring the chimney outside. The design is compact and safe. It warms up very quickly and immediately releases heat into the room. Some people place a hob on top of the stove to cook food or heat water. However, potbelly stoves have one serious drawback - no matter how thick the metal of the stove walls is, it will burn out over time. And the more often you use the stove, the faster this will happen. For this reason, it is better to make such a stove as a temporary or backup heat source, for example, in emergency situations or for additional heating. In the video - a stove made from a gas cylinder for heating a garage: The video above demonstrates a stove made from two gas cylinders, but one is enough to create an effective design. In addition to the cylinder, you will need steel corners (furnace legs), a metal grate for the grate, sheet steel 3-4 mm thick, a door and a chimney pipe of the required length. The tools you will need are an angle grinder, a welding machine, metal scissors, a hammer, a screwdriver and a hammer drill with a set of metal drills. How to make a stove from a gas cylinder: Unscrew the rim with the tap located at the top of the cylinder. If you can’t unscrew it, you can carefully knock it out with a hammer. Fill the balloon with cold water or immerse it halfway into a hole in the ground. In the upper part, make a hole the size of the door of the future oven. Using a welding machine, make a frame for the door from steel corners and attach it to the cylinder. Place the door against the frame in the position in which it will be secured, and make holes for the bolts in the corners. Screw the door to the frame. Where the bottom of the stove will be, cut a hole for the grate and weld the grate. Attach sheet steel side panels to the cut hole on 3 sides. The result should be a box without a top. Weld it to the bottom of the cylinder, turning the open side towards the door - through this passage you will remove the ash. It is important that the box is completely sealed. Install a metal damper to regulate the oxygen entering the firebox. Weld legs from steel corners to the bottom of the cylinder. On the wall located on the opposite side of the door, cut a hole in accordance with the diameter of the chimney pipe. Equip an elbow chimney, then the heat will not leave the stove so quickly. Furnace in production It is a little more difficult to make a stove using a gas cylinder than a potbelly stove, but this work is quite doable even for novice self-taught stove makers. If you do everything according to the instructions, you will get a very effective device that can quickly heat a garage, small country house or change house. The working principle of the furnace is as follows: you pour oil into the fuel compartment and ignite it; air is dosed through the air throttle, which affects the intensity of combustion. The heat of combustion of oxygen here is mainly spent on evaporation - the vapors rush upward and enter the reactor with perforated walls. Fresh air penetrates through the holes, which only enhances the combustion of oil vapors, as a result of which the temperature rises and the pyrolysis process begins. Not only oil burns, but also vapor, so there is practically no waste from operating such a furnace. In the upper part of the pyrolysis compartment, the gases practically burn out and exit into the afterburner chamber, which consists of two compartments: in the first, pyrolysis fumes burn out, which maintain the temperature, in the second, due to the high temperature and lack of oxygen, the nitric oxides of the gases decompose into oxygen and nitrogen. Oxygen supports the afterburning of gases, and the furnace temperature is stably maintained at approximately the same level. The outlet into the chimney pipe from the afterburning chamber should be located as far as possible from the partition - about 20 cm. The efficiency of such a stove is about 80%, which is one of the highest rates among home-made heating devices. As a rule, cylinders with a volume of 50 liters are used for the manufacture of waste oil furnaces. They are cut in a ratio of 2:1 - the smaller part goes to create a reservoir, and the larger part goes to the afterburner. The result is a furnace with a power of up to 30 kW. However, due to the specific fuel, all possible safety measures should be taken - burning waste can cause a lot of trouble. Do not install such a stove in a residential area and prevent access to it by children and pets. Long burning stove To make a long-burning stove from a gas cylinder, you will need a large container of 50 liters. Any wood product can be used as fuel, from sawdust to old furniture and branches of garden trees. Since the fuel in such stoves burns in a thin layer near the surface, they are also called long surface combustion stoves. The pyrolysis process can be carried out in two ways: in a separate small chamber with subsequent combustion of gases in an afterburning chamber (separate combustion furnaces), or the gases will go into a spacious heated buffer compartment, where they will burn out (combined furnaces). To ensure the highest possible efficiency in both the first and second cases, it is recommended to preheat the air that enters the pyrolysis zone. Bubafonya stove The long-burning stove with the funny name Bubafonya is very popular among summer residents and stove makers. In this design, the pyrolysis process is concentrated under special pressure. The image below shows a diagram of such a furnace, from which you can understand the principle of its design and operation. The efficiency of Bubafoni can be 85% or more, while the duration of heat transfer from a unit load of fuel is 18-24 hours. If you need to constantly monitor an ordinary potbelly stove, otherwise you risk freezing, then you can visit Bubafoni only once a day, which is very convenient. The moisture content of the fuel for the stove should be no more than 12%. During the combustion process, you can add more firewood or wood chips, but it is highly not recommended to stop the stove until the fuel is completely burned. Important: To make a Bubafoni stove, you must use a 50 liter cylinder with a diameter of 30 cm, since it provides the minimum permissible volume. Such a stove turns out to be very economical, despite the fact that it can be made at home: Helpful advice: It is best to make a prefabricated chimney, and start assembling it not from the stove, but from the reverse side - from the roof (then it will be more convenient to disassemble it for maintenance and repair). Many people prefer to install a glass with an inspection so as not to disassemble the chimney to remove soot. Gas cylinder stove: photo Finally, we invite you to look at the drawings of stoves made from gas cylinders and see what structures you can build with your own hands. This is what “Bubafonya” looks like inside:

Heating devices are used not only in residential but also in industrial premises. There are a great many modifications of them, because in workshops the conditions are usually not sophisticated. Therefore, they install everything that is affordable and economical - from potbelly stoves to technically sophisticated heating systems.
Today we offer for consideration one of the most interesting stove models. A rocket stove or jet stove is fundamentally different from others in the high degree of heating and convection of the body, which is made either of bricks (stone stove) or of thick-walled metal. This heating device is equipped with a water circuit, connected to radiators and you get an almost complete economical heating system.
The author of the homemade product suggests making our version of a jet stove from an empty propane cylinder. A small modernization, a minimum of parts and you have an excellent option for a heating furnace for a production workshop!

Operating principle of the furnace

The stove consists of a firebox, a heated container and a chimney. The firebox is made in the form of a curved pipe, in which firewood burns in its lower part. Hot air rises through a vertical pipe located in the center of the heated container, which in our case is made of a gas cylinder. Rising upward, hot air heats the walls of the container, and gradually cooling down, it exits at the bottom through the chimney, which creates air convection and draft in the oven.

Materials:

• Propane gas cylinder;
• Square pipe welded from paired corners;
• Metal corner 50x50x5 mm;
• Round chimney pipe with swivel elbows;
• Auxiliary metal elements: plates, corner trims, plugs.

Tools:

• For metal cutting: inverter plasma cutter or grinder with stripping and cutting discs;
• Welding machine;
• Metal straight corner, tape measure, marker for marking;
• Bubble level, hammer, metal brush.

Making a rocket stove

Before you get to work, you must remember that gas cylinders are extremely flammable and explosive. They must be thoroughly rinsed with water that has been left in a cylinder for a while, since even small residues of liquefied gas during cutting can lead to an explosion of the container.

Preparing the balloon

A household propane cylinder consists of a neck, a shell and a bottom. It is usually positioned vertically, so that the shut-off valve remains in the most visible place in the center of the cylinder. You need to get rid of it by lightly tapping it with a hammer.

After unscrewing the fitting with an open-end wrench, fill the cylinder with water to wash off the remaining liquefied gas. Let the water sit for a while, and then carefully tip the container over and drain it. Even after such measures, we carefully transfer the cylinder to the treatment site. Using a plasma cutter, cut off the bottom of the cylinder.

We cut the pipes and scald the firebox

The next step is to cut the metal corners to the size of the loading chamber, firebox and air duct. We cut them with a grinder or plasma cutter, and boil each of them along the ribs.
The connections will be located at different angles. The dimensions of these elements are as follows:

• Vertical air duct – 900 mm;
• Horizontal firebox – 500 mm;
• Feeder or loading chamber – 400 mm.

The firebox and air duct are connected perpendicularly. We cut the ends of these pipes at a miter angle of 45 degrees, and weld them on all sides of the pipe. Since the metal heats up over 1500 degrees Celsius during the welding process, it can lead. Therefore, it would be a good idea to check the accuracy of the connection with a metal corner.

The location of the loading chamber will be inclined, so the feeder pipe must be cut at an angle of less than 45 degrees. We place it on the fuel pipe a few centimeters from the edge of the firebox, where the ash pan will subsequently be located. Using the marking of the pipe section, we make a slot at the junction of the elements and weld it in place.

The firebox must be level and securely fastened. It will be supported by a small piece of corner from which the pipes were made. We cut it exactly to size and place it on the bottom of the cylinder, checking the identity of the straight line between the planes of the cylinder with a metal corner.

We boil the firebox, reinforcing the vertical air duct pipe with metal plates or corners. We mark a seat for it on the wall of the cylinder, and make a slot with plasma or a grinder. The more precise the cut is, the easier it is to scald it later.

We position the firebox so that the vertical pipe inside the cylinder is located strictly in the center. We use a welding machine to weld the bottom and the firebox pipe.

A regular bolt or similar piece of metal will help plug the hole at the top of the cylinder. We insert it into the hole and weld it to the cylinder. You can clean the seam with a sanding disc and grinder.
