How to make an efficient stove from an old gas cylinder. Do-it-yourself gas cylinder stove Potbelly stove from a gas cylinder on long-term wood

The potbelly stove, although it has more than a century of history, has not ceased to be a very popular heating device for small spaces even today.

Such a furnace is made not only from solid sheets of metal, but also various metal objects that can withstand the heat from an intense flame - it can be a barrel, a flask, a pipe or an old gas cylinder.

It is especially popular among avid motorists who, even in winter, cannot refuse improvements in their car, spending all their free time in garages. time. The gas cylinder has an ideal shape, it is practically a potbelly stove, it just needs to be slightly improved: cut off the excess, drill the necessary holes and weld a few pipes! Let's take a closer look at how to make a potbelly stove from a cylinder?

A potbelly stove from a gas cylinder can have a vertical or horizontal arrangement. Some craftsmen make such furnaces even from two cylinders, placing one of them vertically on top of the other, which is oriented horizontally.

However, there are many models, and, having considered different ones, you can choose the one that seems more convenient to use and acceptable in ease of execution.

Naturally, for the manufacture of a potbelly stove from a cylinder, some tools and materials will be required, as well as certain skills in working with them.

What needs to be prepared?

From tools need to collect:

1. welding machine (200A);
2. grinder - "grinder", preferably with discs with a diameter of at least 180 mm;
3. electrodes;
4. circles for grinding and cutting metal;
5. a hammer that cleans the slag from welding;
6. a brush with metal bristles;
7. folding meter, tape measure, chalk or marker for marking;
8. drill and drills of the required diameters;
9. chisel, normal hammer and pliers.

From materials, except for one or two gas cylinders, you must purchase:

1. a sheet of metal with a thickness of at least three millimeters - it is useful for installing a hob and an ash pan;
2. ready-made cast-iron doors, or they can also be made independently from a metal sheet or a piece of metal cut from a cylinder;
3. flue pipe;
4. corner or thick reinforcement - they will be required for the manufacture of legs and grate. The latter can be purchased ready-made (made of cast iron) or arranged using holes drilled in the bottom of the cylinder.

It should also be noted here that for the manufacture of such a stove, both a standard gas cylinder and a small cylinder are suitable.

As mentioned above, a cylinder stove can be vertical and horizontal. You can choose the one you need based on the amount of space allotted for installing the potbelly stove and the convenience of its operation.

Balloon preparation

Proper preparation of the cylinder is a very important event before starting work, especially if the potbelly stove is made from a container in which gas was not so long ago. Residues of gas may remain inside, and when cutting, which is accompanied by sparks, the cylinder may explode.

• Therefore, first you need to unscrew the valve located on top of the cylinder, and free the passage for the exit of residual gas - this procedure will take some time. It is best to leave the container open. for the night on open air or in a well-ventilated non-residential area, or even better - fill it with water to the very top.
• Next, the container is turned over and the resulting condensate is drained. It has a very unpleasant smell, so this process also cannot be carried out in a room where people live.

The washed container no longer harbors any explosive hazard when working with it, and you can safely proceed to the cutting process.

Vertical potbelly stove from a gas cylinder

An ordinary unnecessary gas cylinder is taken

• In the manufacture of this model, the cylinder is installed in its usual position, the neck is completely released, then marking is made using a tape measure and a marker.

A possible marking option for a vertical potbelly stove

• Further, using a grinder (or using a gas or plasma cutter), holes are cut out for the device of the furnace and blower.

• The next step is the installation of a grate between the furnace chamber and the blower. Since this element of the desired shape and size is difficult to find, it is made from reinforcement. It is cut into pieces of the desired size and welded to a pre-marked place.

• Next, doors are installed - cut pieces of metal are perfect for their manufacture. They are installed on hinges welded to the cylinder body.
• It is imperative to install latches or hecks on the doors - they must securely hold the doors during the firebox.
• In the upper part of the cylinder, if desired, you can arrange a small hob. It will always come in handy in order to make coffee or tea or fry scrambled eggs. This panel is made from sheet metal.

• The photo shows a variant of the preparatory base not just for the hob, but for installing a container for heating water on top, made like a samovar. The pipe leaving the firebox will pass through a container of water, heating it.
• All seams with which any parts of the furnace are welded must be airtight.
• The chimney can be installed in the top of the stove or in the side wall. The chimney exits the room through the wall of the building or the roof.

This arrangement of the gas cylinder helps to save space, as the oven is compact and neat. Especially it is well suited for a garage or a small room in the country.

Potbelly stove of horizontal type

• Another version of the cylinder stove, which is placed horizontally, also has its advantage - you can arrange a large hob on it, which will be able not only to warm tea, but also cook dinner.
• In order for the design of the potbelly stove to stand steadily, a reliable stand is welded from a corner for it, and after completion of work, the finished stove is fixed on it using spot welding.
• Work on the cylinder also begins with markings, after which a square hole is cut out for installing the door and a round one for installing a chimney pipe. With a round hole, you may have to get it if there is no cutter. "Bulgarian" is not an assistant here, so at first - drilling holes around the circumference, then - work with a chisel and hammer, and then - final fine-tuning with a file.
• Holes are drilled in the bottom of the future furnace, which will play the role of a grate, and under it a box is welded from a sheet of metal into which ash will be poured.

In the role of a grate - rows of drilled holes

• The same chamber will be a blower, so an adjustable door is installed on it so that you can reduce or increase the air flow to establish the desired traction.

You can make your own door...

• The door for this furnace can be made independently by scalding the part cut out of the cylinder, or you can install a finished cast-iron part that already has a frame. The second option will be easier to install, and it is already equipped with a latch to securely close the firebox.

... or buy ready-made in the store

• After installing the door, the potbelly stove is fixed on a stand or legs of the desired height are welded to it.
• Then a pipe is welded onto which a chimney pipe will be installed. It can also be removed through a wall or roof.

Will a small balloon fit?

You can also work with a small balloon. It is made according to the same plan as the horizontal type stove.

• But in this embodiment, instead of drilled holes in the bottom of the potbelly stove, a cast-iron grate is installed. a window of the required size was cut out for it.

• The blower in combination with the grate is welded as follows.

• Next, the legs are welded onto the ash box, the structure is turned over and installed on top, and the chimney pipe is fastened by welding
• After completing work on the potbelly stove, it is installed in a permanent place and the chimney is taken out into the street.

Video: How to make a super wood-burning stove from a used cylinder

The proposed options are only a small part of what was invented by folk craftsmen. See how the craftsman combined brickwork and a gas cylinder in one potbelly stove:

If you have an idea about working with the tools described above and all the necessary materials, you can try to make this convenient, and sometimes irreplaceable oven yourself. By doing it yourself, you can save a fairly large amount, as well as make an already unnecessary gas cylinder function. The most important thing is to take a responsible approach to this work and do it slowly, checking each action.

Or a workshop is perfect for such a stove as a potbelly stove. While wood is burning in the stove, it warms up the room perfectly, consuming little fuel. In order for the room to be stably warm, the stove must be well sealed and have a blower with an adjustable damper. As a result of air dosing, the stove can burn from one tab for quite a long time. The author assembled a small potbelly stove for himself from a gas cylinder, on the stove there is a small hob on which you can heat a kettle or fry scrambled eggs. If you are interested in the project, I propose to study it in more detail!

In many private households there is an old liquefied gas cylinder. Many useful things can be made from this object, for example, a simple heating device.

If there is a desire and a welding machine, then a potbelly stove from a gas cylinder with your own hands can be made without any problems. Of course, some additional materials will be needed.

A potbelly stove is a primitive version of a metal one. Such a device works extremely simply: firewood is laid in the furnace, they burn out, the furnace body heats up and gives off heat to the surrounding air. Smoke gases are removed through the chimney, and the ash is poured through the grate into the ash pan, which should be cleaned periodically.

They heat a potbelly stove with other combustible materials: diesel fuel, coal, peat, household waste, etc. If desired, on such a stove you can cook quite successfully. This moment should be considered even before the start of the manufacture of the structure in order to make a flat hob.

The potbelly stove is a combustion chamber made of thick metal with a loading door, a chimney, a grate and a blower. You can use an old gas cylinder as a housing

For a potbelly stove, you need to choose a special place, finished with fire-resistant materials. It is desirable that she stand to the side, where no one accidentally touches the body and does not burn herself.

If desired, the upper part of the vertical potbelly stove from an old gas cylinder can be turned into a hob of modest size

Such a metal structure weighs a lot, so there is no question of any mobility of the device. It will be difficult to move the potbelly stove to heat different rooms.

Such stoves are usually used to heat utility rooms in which there is no electricity or where it is supplied intermittently: a garage, a barn, a workshop, etc.

From two gas cylinders connected perpendicularly, you can make an improved version of the potbelly stove, which allows you to save more heat and get high returns when burning fuel

Another problem is the low efficiency, since part of the thermal energy during the combustion of wood literally flies into the chimney. There are various ways to keep warm and modify the potbelly stove a little to make it work more efficiently.

Finally, you need to take care of good ventilation of the room in which the potbelly stove is installed, since such a device burns a large amount of oxygen during operation.

So, a potbelly stove consists of a metal case, the role of which is usually “invited” to an old gas cylinder. In the case it is necessary to make two doors: large and small. The first serves to load fuel, the second is needed as a blower through which air enters the combustion chamber to ensure the combustion process and traction.

To begin with, it is recommended to open the cylinder and bleed off the remaining gas. Of course, this should be done outdoors, not indoors. Then you need to drain the remaining liquid from the cylinder, condensed inside. This substance usually has a pungent and unpleasant smell, so it is best to prepare a small container with a lid for it in advance so that it can be neatly packaged and discarded immediately.

There are no particularly strict requirements in terms of parameters for the design of the potbelly stove. The larger the combustion chamber, the more spacious the room will be able to heat the unit

If the condensate is accidentally spilled on the floor in the room, the specific aroma may remain for a very long time. After all these operations, the cylinder is still not ready for contact with the welding machine, because residual gas vapors remain inside.

It is necessary to fill the cylinder with water to the very top in order to completely expel all the gas from it. After that, the water is drained, now the balloon can be cut without problems.

Stage number 2 - manufacturing and filling the case

A real home master should know how to make a potbelly stove with his own hands from a gas cylinder. Such an oven will warm in severe frost and help cook food in a summer cottage where there is no main gas. This is not so little.

Collapse

What is the best bottle to use?

The best option is the use of gas propane cylinders of 50 liters. And that's why:

• small mass;
• sufficient volume to obtain optimal power;
• Sufficient size to burn any fuel.

Why gas? If you have a dacha without a main gas pipeline, you will always find such a cylinder on the farm. Yes, and its thickness is optimal - 4 mm. This thickness is sufficient for burning solid fuel, the cylinder is quite light.

Below are step-by-step instructions for the independent manufacture of the first two designs: a three-way potbelly stove and a pyrolysis potbelly stove for 2 chambers. Before manufacturing, it is necessary to properly prepare the cylinders for working with the grinder and welding. The procedure should be like this:

• Unscrew the valve at the top of the cylinder and remove the remaining gas. The valve must be completely dismantled.
• After the remaining gas has come out, turn the balloon over. We remove the condensate into a previously prepared container. The condensate has a strong unpleasant smell. Therefore, the container after use will have to be thrown away.
• We turn the balloon over again and fill it with water to the brim to force out all the remaining gas.
• After that, we drain the water.

Time of effective work of a potbelly stove - 2-4 hours.

Do-it-yourself three-way potbelly stove

Three-way potbelly stove

A three-way potbelly stove (pictured above) is two gas vessels of 50 liters welded to each other at a right angle. The principle of operation is as follows:

• The first is actually a horizontal potbelly stove from a gas cylinder on wood. It is equipped with all the details that are typical for a stove: a blower, a loading chamber for firewood, grates. Firewood is loaded here and fired up.
• The second vessel is a unique design in its simplicity and genius. It is divided by internal partitions in such a way that the smoke from the combustion of fuel, passing through it, changes the trajectory of movement three times. The speed slows down and the furnace body gives off more heat. In the end, through the outlet pipe, the smoke comes out.
• Additional ribs are used to increase the heating surface.
• As in a traditional oven, the air supply is regulated through a blower.

Expert opinion

Pavel Kruglov

Baker with 25 years of experience

Such a wood-burning stove from a gas cylinder is quite capable of delivering about 10 kW of heat. This is enough to heat a room of 100 m2. It can be a warehouse, a barn, a greenhouse or a garage. Such a simple design of the furnace is capable of producing an efficiency of up to 55%.

On such a potbelly stove from two gas cylinders, it is quite possible to cook food.

Before proceeding with the manufacture, we will figure out what materials and tools we will need and prepare the necessary drawings. Very good if you have the skills of a welder. If not, then any specialist in ready-made drawings will bring your project to life. A video that is easy to find on the Internet can also help.

Materials and tools

We will need the following tools:

• portable welding machine
• "Bulgarian"
• drill
• drill
• other tool.

There are also few materials:

• electrodes
• cutting wheels
• 2 gas cylinders for 50 liters
• sheet 2 mm thick
• fittings with a diameter of 20 mm
• others

Step-by-step instruction

Scheme of a three-way potbelly stove

• We make blanks from metal according to the drawing above.
• We cut out the necessary holes in the balloon. One is for the stove, the second is for the smoke outlet.
• Cut off the bottom of the second bottle. At the end, we cut a hole for a pipe with a diameter of 100 mm. We cut the balloon so that it fits snugly on the first one, as shown in the drawing above.
• Make a grate.
• We make a blower. We weld the legs, hinges and frames of the doors.
• We make doors. We seal all junctions.
• Scraps from the cylinder should be used for partitions in a vertical cylinder.
• Weld one cylinder to another, weld the chimney.
• Weld additional ribs to increase the heating area.

Production of a pyrolysis two-chamber oven

The photo above shows a potbelly stove from a gas cylinder. This version of the potbelly stove is more compact and economical. Instead of two 50 liter propane tanks, we need 1 24 liter propane tank and 5 pipes with a diameter of 57 mm and a length of about 400 mm.

The principle of operation is as follows:

• The first propane tank is similar to the previous version. The only difference is that instead of grates, slots are cut on top of the cylinder itself.
• An opening is made on top of the balloon. 5 heat exchanger pipes fit there. Through these pipes the smoke rises to the secondary chamber. While making this path, the heated air gives off part of the heat to the room.
• Additionally, warm air is supplied to the secondary chamber through a separate channel. The effect of pyrolysis is created - the smoke burns out in the fuel chamber and releases additional heat. And only after that they finally come out.

The power of such a horizontal potbelly stove can reach up to 5 kW. This is enough to heat 50 m 2 of usable area.

Making a pyrolysis (long burning) two-chamber stove is not much more difficult. It is more compact, but has less power. In the same way, we will prepare tools, materials and you can make the necessary drawings.

Materials and tools

You will need the following materials:

• electrodes
• cutting wheels
• 1 gas bottle for 24 liters
• sheet 2 mm thick
• corner for the manufacture of "legs"
• fittings with a diameter of 20 mm
• pipe diameter 57 mm
• pipe diameter 20 mm
• others

You will need the same tools:

• portable welding machine
• "Bulgarian"
• drill
• drill
• other tool.

Below is a drawing of a potbelly stove from a 24 liter gas cylinder.

How to properly install a potbelly stove and chimney?

In order for the balloon furnace to work correctly and the efficiency to be maximum, it is important to correctly install it. Otherwise, smoke may form in the cold room. All fire and safety regulations must also be observed.

Installation requirements:

• Any combustible objects should be no closer than half a meter from the stove. Distances to fireproof objects are not standardized.
• If you are heating a greenhouse, keep the stove away from glass and plants.
• Wooden flooring must be covered with a metal sheet. From the side of the firebox, a patch of dimensions 50x70 cm is also covered.
• If the walls are made of wood, it is worth protecting them with fireproof material.
• The potbelly stove is placed at a height of 200 mm.
• Point the fan at the potbelly stove. The additional air flow due to convection will increase the efficiency.
• Clean the blower from the ashes in a timely manner.
• Insulate the chimney. This will significantly reduce the heat loss of the stove from the gas cylinder in the garage.

trial firebox

After the potbelly stove is made, you need to test it in action. The first furnace will show all the defects. The oven must be heated before painting. The test is carried out in the following order:

• Ignite the stove with a small amount of fuel. The first stage lasts 30-40 minutes.
• If smoke is not visible anywhere, next time we make a full bookmark and heat the stove. Our goal is to burn out the old paint.

If smoke penetrates somewhere, these places must be sealed. After the test, the oven must be coated with heat-resistant paint.

Conclusion

What type of potbelly stove from a gas cylinder to choose is up to you. She will become an indispensable assistant. Advantages:

• The cylinder body has an ideal thickness of 4 mm. This ensures optimum thermal conductivity. The dimensions of a standard 50 liter bottle ensure ideal efficiency.
• Compact. Can be used in tight spaces.
• Improvised materials and elementary design are used.
• A wood burning stove from a gas cylinder makes it possible to install a surface for cooking.
• Does not require the manufacture of the foundation.

The disadvantages include:

• Fairly low efficiency
• Work only on solid fuel. Although, there is a modification of a potbelly stove from a gas cylinder for testing.
• The need for constant cleaning.
• The stove from a gas cylinder on wood cools down quickly.
• Use as a source of constant heating is unprofitable.

As you can see, the advantages outweigh the disadvantages. They put such horizontal stoves from a gas cylinder where it is impractical to carry out a centralized heating system and there is no main gas.

When installing a potbelly stove, it is important to strictly comply with fire safety requirements.

Factory stoves are expensive, so it is advisable to make a stove from a gas cylinder to a garage with your own hands from improvised materials.

If you do not have the skills of a welder, any specialist will manufacture such a product for you according to the above drawings.

The stove is a necessary and useful device, which is most often used for heating residential premises or outbuildings, cooking and other purposes. Despite the wide range of models that can be purchased today, many people prefer to make them with their own hands.

For these purposes, you can use dimensional barrels or sheet material, but gas cylinders are especially popular, since their use as a basis can greatly simplify the process. The main types of furnaces that can be made in a similar way will be discussed in this article.

Types of furnaces from a cylinder

As already mentioned, you can independently make ovens of various types, below we will consider all the features of the most popular and interesting options:

1. The potbelly stove belongs to the emergency-reserve type stoves, this is one of the most popular and recognizable varieties. It is distinguished by its versatility and versatility, depending on the volume used to manufacture the cylinder, it can be used both in city apartments and in suburban buildings. The only significant drawback is the short service life, the potbelly stove cannot function constantly, since the thin metal of its base is subject to gradual burnout. However, in case of a sudden power outage, it can become the main assistant for warming up the room.
2. is made more complicated than a standard potbelly stove, financial resources for this process will also have to be spent much more. However, this option still enjoys continued popularity, which is due to the ability to warm up sheds, garages, workshops and other non-residential premises, without the need to use expensive fuels. With such apparent advantages, there is no mass production of this variety in the factory, since it has been banned by the fire departments. The main distinguishing feature will be the presence of a special fuel tank into which oil is poured.
3. Bubafonya is one of the most popular options for long-burning stoves. This is easily explained by the fact that its service life is much higher than that of a standard potbelly stove, while the efficiency index is very high, and heat will be released for another day. It is the combination of economy and efficiency that has made bubafonya one of the leaders in its class.
4. The rocket stove is a very original option. Its manufacture will require a significant investment of time, effort and financial resources, but the resulting device will be able not only to heat the room, it can also be used as a stove bench. The rocket is the best option for people who, for whatever reason, do not want or cannot build a full-fledged brick oven, the consumption of materials for which is several times higher.

Choosing a basis

As you know, most gas cylinders are different, the main criterion for their classification is volume. Therefore, it is on this characteristic that you need to rely on when choosing the basis of a future device, the main recommendations and nuances are given below:

1. A volume of 5 liters is not suitable, as it will not be enough anyway. for the manufacture of a functional oven that can perform its functions with high quality.
2. A volume of 12 liters will already be suitable for the manufacture of a universal device, which shows good performance in small spaces. Its power will be approximately 3 kW.
3. The volume of 27 liters makes it possible to make an oven that can also be used in small spaces and moved if necessary. The power of this option will be about 7 kW, but even this indicator is not enough in some situations.
4. A volume of 50 liters is the most appropriate indicator, since it will ensure complete burnout of the fuel used. From such a cylinder, you will get a stove with a height of at least 85 cm; you can easily purchase it at specialized gas stations.

Another important criterion is the case material: only those options that are made of solid metal should be used, since composite alloys are too low in heat resistance.

Do it yourself

Potbelly stove from a balloon

Several types of potbelly stove can be made from a gas tank, the following is an instruction, following which will allow you to get a horizontal model:

1. Place the balloon used as a base in this way so that it is in a horizontal position corresponding to its final form.
2. The top must be cut, which will allow you to place a grate inside the structure.
3. The basis for the lattice will be ordinary reinforcement, while the rod is bent in the shape of a snake. For fasteners, it will be enough to fix it in the required place, and then weld it to the walls.
4. Draw a circle on a sheet of steel, the diameter of which will be equal to the same value of the outer side of the tank.
5. The marked circle is cut out of the sheet with any suitable tool, after which several holes in the form of rectangles must be marked on it. One will serve as a blower, and the other will supply heat to the fuel chamber. You can cut them with a chisel or grinder, it is more convenient to use the second version of the tool.
6. Curtains are welded to the lid, after which you can do the installation of the door, in most cases it is bought in advance in the store.
7. The doors are additionally glued with asbestos cement cord along their entire contour., after which the entire structure can be welded to the main tank.
8. Now you can move to the back of the potbelly stove, where it is necessary to cut a hole, the dimensions of which will be equal to the diameter of the pipe, it is necessary to remove smoke.
9. At the final stage, a chimney is welded to the hole made, as a basis for it, a pipe of the appropriate size and sufficiently thick walls is suitable. After completion of this stage, the potbelly stove is ready for operation.

Bubafonya oven

Bubafoni are very popular today, as they belong to long-burning furnaces. They can be made from a variety of materials and fixtures, but using a gas tank for these purposes is the easiest.

Below is a guide to help you through this process:

1. Cut off the top first gas bottle.
2. To the part of the structure that will play the role of a cover, you need to weld clamps or stops, it will perform the function of fixing it and fastening it on the device case.
3. If the edges of the cut part turned out to be sharp, then it is recommended to bend them inward to avoid accidental injury. For these purposes, it is most convenient to use a sledgehammer.
4. The part that is the lid will also need to bend the edges, but, on the contrary, to the outside. This will allow you to achieve the tightest contact when closing the bubafoni.
5. Now special attention should be paid to the manufacturing process of the piston. To do this, you will need to prepare a metal pancake with a diameter smaller than that of the cylinder so that it can move freely inside it; a pipe for supplying air to the lower chamber of the furnace; several metal pieces for welding to the bottom surface of the pancake.
6. A hole should be made in the center of the metal pancake, the dimensions of which will be equal to the diameter of the selected pipe. Several metal elements are welded to its lower part, so that when the piston is lowered, the pancake does not fit too tightly to the firewood, otherwise the necessary amount of air will not flow into the lower part of the bubafoni. It will be enough to have six segments that resemble rays directed from a hole in the center.
7. The pipe must be cut so that its length is about 6-10 cm, depending on the height of the tank. Then it is inserted into the hole in the center of the pancake and reliably equated to it, while ensuring tightness is not necessary: ​​if gaps remain in the structure, they will additionally contribute to the flow of air into the oven.
8. In the wall of the cylinder, just below the level of the lid, it is necessary to cut a hole into which a pipe will then be inserted and welded to remove smoke. The recommended diameter is 1 cm, this indicator will be quite enough to ensure normal traction. The length of the horizontal direction of the chimney is about 40 cm, after which it changes direction and rises, the minimum length in this section is 2-3 meters.

Furnace in production

A working furnace or, as it is called differently, an oil garage stove is also much more complicated in design than a classic potbelly stove, but many people prefer this particular variety, since it allows the use of used engine oil and other similar substances as the main fuel, which are essentially waste.

For its manufacture, it is proposed to use the following algorithm of actions:

1. During operation, the gas cylinder must be kept exclusively in a vertical position. To do this, it is filled with water and half buried in the ground or fixed in a fairly narrow pan, but it must be heavy enough so that the tank does not outweigh it.
2. Make marks on the top of the balloon and cut it off. For these purposes, a grinder is used, and when a cut is formed, water will begin to flow out, which was previously poured into the tank. It is necessary to immediately stop the workflow and wait until the liquid goes below the cut level, and then finally eliminate the upper part. It must be saved, because in the future it will serve as a fuel tank.
3. At a distance of about 0.7-1 cm from the cut, it is necessary to make a round hole, it will be required for the installation of the chimney pipe. Its diameter should be equal to the same indicator of the prepared pipe with a total length of about 4 cm. It will need to be inserted into the hole and welded, while maintaining the tightness of the seams.
4. A vertical pipe will be welded to the horizontal part of the chimney, whose height is 3.5-4 meters.
5. Now the cylinder should be raised above the floor surface; for its convenient fixation, it is recommended to weld metal legs on the bottom. Similar measures are required to make a square-shaped hole, which will serve as a blower. It will also need to be equipped with a door, which does not have to be made by yourself, but can be purchased at the store. It will be required to manually control the volume of air that will enter the furnace.
6. It is necessary to lower the fuel compartment to the bottom of the cylinder, it can be easily made from a pipe 7-10 cm high and about 1.5 cm in diameter. At the same time, it must be ensured that it is hermetically welded at the bottom to exclude the possibility of fuel leakage. This compartment will also need a cover, it can be made from ordinary sheet metal material, in which two round holes are made at the same stage. It will be necessary to insert and weld the corresponding pipe into the central hole with a diameter of 1 cm, and place the second hole with a diameter of 0.5-0.7 cm closer to the edge, it will be required to fix the movable cover.
7. The pipe leading from the mounted cover must be identical in length to the height of the gas tank. A round metal element with the same diameter as that of the main cylinder is welded to its upper end, which will give this mechanism a resemblance to a piston.
8. The entire piston structure is inserted into the cylinder, while it must be immobilized, so the edges of the cover will be welded to the walls of the tank.
9. The final stage consists in pouring used oil into the appropriate compartment and conducting the first test of the furnace for mining, this procedure is carried out exclusively on the street. If everything goes well, then the structure can be brought indoors and connected to the chimney system, after which it can be used for its intended purpose.

Rocket oven

A rocket stove that allows you to create a heated lounger will be the last option considered. It can also be made on your own, detailed instructions are given below:

1. Initially, the bed is prepared, this process involves the design and construction of a wood frame. The shape and configuration is selected depending on individual preferences. As a material, it is best to use a beam with a section of 1x1 cm, the frame should form cells with dimensions of 60x120 cm, and the area directly under the stove should have dimensions of 60x90 cm.
2. A grooved board is used as a sheathing material for the frame., the recommended thickness is approximately 0.5 cm.
3. All parts and structural elements made of wood, without fail, must be treated with a biocide and several times with a water-based emulsion.
4. A special kind of cardboard is laid on the floor surface in the place where the rocket stove with sun lounger will be installed, which is made from basalt fibers. The minimum layer thickness is 4 mm, all other parameters depend on the shape and dimensions of the structure.
5. Directly at the installation site of the furnace, you will need to lay a sheet of roofing iron. The size is selected in such a way that the sheet protrudes outward from the side of the firebox by about 2-3 cm.
6. The frame is transferred to its permanent place, it must be installed securely enough so that it does not stagger or sway. At a distance of 12-14 cm from the lounger, holes are made in the wall surface, which will be required for the installation of the chimney.
7. Along the perimeter of the structure, formwork must be installed, the height of which will be at least 0.5 cm. It will be necessary to pour adobe into it and level the upper surface, focusing on the sides of the formwork.
8. The process of drying the mixture will be long and will take about 2-3 weeks, during which time you can make the basis for the furnace. Initially, you will need to cut off the top of the gas tank to get a hole with a diameter of 20-22 cm.
9. A round steel is installed in the resulting hole, and a second cut is made below, as a result of which a cover should be obtained, along the perimeter of which there is a thin sheet of steel about 0.5 cm wide.
10. At a distance of 2-2.5 cm from the welded steel, two round holes are made into which bolts are securely tightened.
11. The lower part of the gas cylinder is cut off at a distance of 0.7 cm, after which a round hole is made in the bottom, through which the riser will enter the tank. In this case, asbestos cord can be used as a gasket that provides sealing.
12. After that, it will be necessary to make through holes in the steel casing through the holes in the cylinder and determine the depth of the tank in order to understand the required parameters of the riser. A pipe with a diameter of 0.7-1 cm is suitable as a material for it.
13. A furnace tank is built into the blower and flame tube at an angle of 45-60°, while the secondary air channel is separated. The riser itself is welded into the flame tube through a pre-drilled hole. The blower is supplied with a door for manual control of the supply of air volumes, tightness is not required.
14. At this stage, the entire structure must be processed heat-resistant type of lining.
15. Now you can make a shell, for this a pipe with a diameter of about 20 cm is suitable, from below, a bottom with a thickness of at least 1.5 mm should be welded to it.
16. An additional layer of thermal insulation is applied to the formwork, and after it has completely dried, a furnace structure is mounted on top.
17. A hole must be made in the lower part of the shell through which it will be connected to the cleaning chamber. Corrugated pipes are used as a material for the connecting channel, which pass under the lounger.
18. After installing all the components, you can not wait for all the working solutions to harden and pour about five layers of sifted sand into the shell, moisten it and slightly moisten it. A layer of clay of medium fat content is poured on top.
19. After completion of all work, the installation of another formwork is required., but already along the outer contour, it will also be filled with adobe in the same way.
20. Corrugated pipes under the bed at the junction with the furnace elements should also be treated with adobe to improve the fixation of the structure. The covers and doors of all chambers are tightly tightened with bolts.
21. After 2-3 weeks, the adobe will dry out and you can move on to simpler work: elimination of formwork, coating the structure with special mortars and installation of additional plank flooring. Features of decorative finishes will depend on the personal preferences of each person, after their completion it will be possible to proceed with the first tests of the rocket stove.

Operating rules

In order for the operation of furnaces made from gas cylinders to be safe and not entail negative consequences, it is necessary to know and follow some general rules:

1. When used to kindle liquid fuels they are not allowed to be added to the stove during combustion.
2. The cylinder and individual elements of the furnace will actively heat up during operation. therefore do not allow them to come into direct contact with wood or other flammable surfaces.
3. The chimney must be periodically cleaned, otherwise it will not function properly. It is best to carry out this procedure after each use of the oven.

1. It is recommended to start building a chimney not from the stove to the exit to the street, as is usually done, but vice versa. At the same time, it should be of a collapsible type, which will facilitate the mandatory cleaning process.
2. Complex stoves are used to heat very large rooms made from several cylinders at once, but it is best to entrust this process to people who already had such experience.
3. When choosing the type of furnace, you need to think in advance about the issue of fuel extraction. For example, in the presence of used oil, the corresponding type of furnace is well suited, and in its absence, it is better to put a bubafon that runs on virtually any fuel.
