Potbelly stove made from a gas cylinder. Exhaust stove from a gas cylinder - instructions for self-assembly

With the onset of cold weather, a caring car owner is looking for an opportunity to warm up his “iron horse”. Being left without a means of transportation due to low temperatures is an unpleasant pleasure. The room intended for parking a car must have a stable temperature all year round. Otherwise, the equipment may simply rust. Today we will talk about how to make a stove for a garage from a gas cylinder.

Features, types and functionality

There are several ways to achieve an optimal climate in a car box - from basic thermal insulation in the walls, ceiling, roof and floor to installing a central and natural heating system. An average option in terms of labor intensity and budget would be an autonomous heater - a stove made from a used gas cylinder.

Particularly handy car owners have long thought through the design of such stoves down to the smallest detail. The idea of this garage heating itself is not new, but it has a number of features, which are described in detail below.

Garage heaters made from gas (usually propane) cylinders are much more economical and functional than other homemade stoves. Their main advantage is that they are convenient for thermal decomposition of fuel. The elongated shape of the gas cylinder is optimal, therefore it meets the basic requirements of the firebox without additional modifications. Only two holes are enough - for the access of oxygen and the release of carbon dioxide into the chimney.

Such “potbelly stoves” are usually divided into two types – vertical and horizontal. If desired, they can be combined.

Pros and cons

The positive aspects of homemade stoves include:

excellent thermal conductivity (provided by the thick metal walls of the cylinder);
convenient dimensions (can be made to fit your garage);
ease of manufacture and maintenance;
availability consumables and fuel.

Among the few disadvantages, one can highlight only the ability to use a limited number of types of fuel (wood, coal, fuel briquettes), and with a vertical design there is also the need to adjust the size of the logs to the length of the firebox.

Design features and operating principle

The “potbelly stove” does not have any special design differences from its relatives in terms of solid fuel. It consists of three departments:

direct fireboxes with a grate (fuel burns in it);
blower (provides access to oxygen and space for ash);
chimney.

To make the operation of the stove convenient and safe, the firebox and vent are equipped with doors with a bolt. These additional elements the designs improve ignition, reduce the risk of coal falling out and unintentional combustion, and by adjusting the size of the gap in the door, you can reduce or increase the intensity of oxygen supply to the oven.

Doors can be of absolutely any shape. It is only important to take into account standard size logs, as well as the convenience of their installation.

An important element homemade stove The grate is made from a gas cylinder. Its function is to retain firewood, as well as to conveniently sift through loose pyrolysis elements. Wood is burning on the grate. Consequently, the material from which the grate will be made must be as durable and heat-resistant as possible. For manufacturing, fittings with a diameter greater than 10 mm are ideal. The rods are connected by welding.

You can install a potbelly stove where there are no problems with the convenience of leading the chimney pipe to the street. Adjacent wooden walls for the purposes fire safety It is better to surround it with sheets of metal so that when heated, a fire does not occur. This type of stove heats the room very quickly, so they are convenient in emergency situations that require instant heating.

Materials for production

In addition to a propane cylinder (it is better to choose an all-metal cylinder of fifty liters and three decimeters in diameter - this volume is enough for waste-free pyrolysis), you will definitely need corner stands as legs, a grate for the grate, steel sheets (4 mm), a door and a chimney pipe of optimal length . From necessary tools you will need to purchase:

grinder;
welding;
metal scissors;
screwdriver set;
hammer drill

Algorithm of actions

Before you begin building your oven, make sure you have all the supplies you need for safe operation. When working with an angle grinder, be sure to use protection. Create your own drawings.

First, you should unscrew the rim with the tap, which are placed on top of the cylinder. If it doesn’t budge, you can try to knock it out quietly with a hammer.
For stability and safety, fill the container with water or bury it halfway in the soil. So, you will provide yourself comfortable conditions work and completely empty the cylinder of accumulated gas.

At the top you need to cut a hole the size of the future oven door.
Weld a door frame from metal corners, and then attach it to the front wall of the cylinder.
Attach the door to the frame in exactly the position in which it will be convenient for you to open it when firing the stove. Drill holes in the corners of the door for the bolts. Screw the door to the frame.

Decide on the hole for the grate and the size of the blower. Cut a hole in the bottom for the grate. Weld the grate.
Place walls made of steel sheets on the slot on three sides (it will look like a box without a lid). Weld it at the bottom of the cylinder, placing open part to the door - this way you can remove ash without any problems. Try to keep the box without holes. Sealing will provide excellent traction.

Do not forget about the metal damper, which will dose portions of oxygen used during combustion.

A stove from a gas cylinder can be installed where heating cannot be organized in any other way: in the garage, country house, change house.

If you have the desire and time, you can do all the work yourself.

This article will help you remake it yourself gas cylinder into a heating or heating-cooking furnace.

Here you will find drawings and instructional videos with which you can make a stove using waste oil, coal or wood.

Types of gas cylinder stoves

A do-it-yourself stove made from a gas cylinder is considered the easiest option for making or heating apparatus for testing.

The cylinder can easily be converted into a housing for the stove. To work, you will need a grinder and an inverter or any other welding machine.

The shape of the cylinder allows us to produce a stove with a spherical firebox. Firewood in a stove of this shape burns slowly - the result is a kind of heat generator capable of heating a room for hours with one load of firewood.

Homemade stove from a gas cylinder long burning can be used in different ways:

as a heating and cooking room in residential premises;
as a heating room for heating one or two rooms;
as a cooker for use in the summer at the dacha;
as an emergency portable option for use in case of failures in the main heating system.

Advantages of stoves made from gas cylinders:

you can get a long-burning apparatus at virtually no cost, since the system is assembled from standard inexpensive elements;
all work can be done independently, no need to look for specialists;
suitable for heating baths;
Video materials with positive experience in creating furnaces of various designs are available;
easy operation.

The disadvantages include the fact that the work should be carried out according to reliable drawings - otherwise the design will not have the required efficiency.

For the job you will need to select a suitable cylinder. You should opt for an all-metal cylinder with a volume of 12 or 27 liters.

However, for a full-fledged heating device, a gas cylinder with a volume of 50 liters and a diameter of 30 centimeters is chosen. In a container of this volume you can burn any fuel, including coal.

Even before starting work, you should decide what type of fuel the stove will operate on. If you need a long-burning furnace, then it is better to provide the possibility of loading coal into it.

A long-burning stove can be made small, using only wood - for this purpose it is equipped with the ability to regulate draft.

The most difficult to manufacture are heating devices using liquid fuel: waste oil, diesel fuel. But a waste oil stove allows you to reduce heating costs, since oil is inexpensive.

For a beginner, it’s better to start with simpler designs, for example, try converting a gas cylinder into a regular potbelly stove.

Solid fuel stove

How can you make a stove from a gas cylinder? The first question that arises even before starting work is: what is the best way to position the cylinder - horizontally or vertically?

If you want to use the stove for cooking, you will have to place the cylinders horizontally.

In the vertical version, grates will have to be installed inside the cylinder; in the horizontal version, this can be done at will.

But in a horizontal design, you will have to weld a tray to collect ash, and in a vertical design, when installing the grates at a sufficient height, you don’t have to make an ash pan.

A potbelly stove will require cast doors for the ash pan and fuel chamber.

Home craftsmen make them themselves from a piece of metal cut from a cylinder when making a hole for the combustion chamber.

In this case, you only need to purchase hinges and a latch handle. For a purchased door, you will have to weld a frame welded from corners onto the cylinder around the perimeter of the holes, and then bolt the fittings onto it.

Before you start cutting or welding metal, you need to empty the container of gas. The cylinder is filled to the top with water, then it is drained and only after that they begin to work.

Stages of manufacturing a horizontal potbelly stove:

cut off the upper part of the container with a grinder;
installed inside the cylinder grate from bent reinforcement;
the fittings are welded to the container;
cut out a circle equal to the outer diameter of the cylinder from steel 4 mm thick;
rectangular holes are cut in the circle - the first for the firebox, the second for the ash pan;
weld a steel circle;
secure the doors;
cover the doors along the contour with asbestos cement;
begin to re-equip the rear part of the stove - cut out a hole for the chimney equal to the diameter of the pipe;
weld a chimney from a thick-walled pipe.

When the cylinder is positioned vertically, the result is a structure that takes up minimal space.

This cylinder stove is suitable for a bathhouse, a small living space, and can be placed in a garage.

Stages of manufacturing a vertical potbelly stove:

cut off the upper part of the cylinder with a grinder;
cut out on the front of the future stove big hole under the firebox, below - under the ash pit, through which the structure will be cleaned of ash;
A grate made of reinforcing bars is lowered inside the cylinder and welded to the walls;
a curb is welded onto the holes under the doors and covered with asbestos-cement cord;
the top is welded; it was cut off only to install the grate;
a chimney opening is made on top or on the side.

Stove-bubafonya and stove-rocket

An ordinary potbelly stove has a significant drawback - low efficiency. A huge amount of heat escapes through the chimney.

In addition, as soon as the fire goes out, the structure immediately cools down. Pyrolysis furnaces, that is, devices capable of maintaining prolonged combustion, do not have these disadvantages.

The simplest pyrolysis oven can be made from a gas cylinder. Masters call such devices bubafons.

The bubafonya stove made from a gas cylinder was invented by a craftsman from Russia. This happened recently, but bubafonya has already become very popular.

How does a “bubafonya” type device converted from a gas cylinder work? A movable piston is installed inside the container, dividing the container into two parts.

Fuel (wood) burns under the piston, and above it - gases released from the wood as a result of pyrolysis.

This operating principle leads to firewood burning in the “reverse order” - from top to bottom.

Reverse combustion occurs more slowly than usual, in which oxygen is supplied to the fuel chamber from below, through the ash holes.

In a bubafon, air is supplied to the firebox by a piston axis, which is a hollow tube. Oxygen enters the pyrolysis chamber through openings cut into the end of the gas cylinder.

Dividing the firebox into two compartments allows the wood, even with a lack of oxygen, to burn to the end without turning into coal.

The system is so effective that a gas cylinder burner on one stack of firewood works for 4 – 6 hours.

There are reliable reviews that bubafonya from a 200-liter barrel works on one filling for a whole day.

Bubafonya can be used for water heating. To do this, the gas cylinder is enclosed in a water jacket using another metal casing, and a water pump is connected to the system.

The rocket stove was developed as a design for survival in extreme conditions. She has high efficiency and maximum safety.

At the same time, a homemade rocket stove is so simple that a non-professional can make it. Rocket stoves use the principle of pyrolysis, that is, fuel decomposes into volatile substances under conditions of oxygen deficiency.

The simplest pyrolysis furnace can be made from any cylindrical metal container, for example, a barrel or a gas cylinder.

Rocket stoves can be equipped with beds. Such structures are still used in China and Korea for heating peasant houses.

Structurally, a rocket stove made from a gas cylinder consists of a blower, a fuel chamber with a blind lid, a channel for introducing oxygen into the pyrolysis chamber, a flame tube in which gases are burned, and a chimney.

Liquid fuel stove

In individual farms, it is sometimes possible to use used motor oil. In this case, heating costs are sharply reduced.

To burn oil, you need to assemble a special stove that runs on liquid fuel. A working heater and a simple wood stove operate on different principles.

At first glance, a waste oven is no more complicated than a saucepan, but complex chemical and thermal processes take place in it.

A gas cylinder exhaust furnace consists of the following parts:

oil containers;
flap that regulates combustion;
oil filling holes;
chimney.

To make a stove from a gas cylinder, tanks with a volume of 50 liters are used.

The cylinder is sawn in a ratio of 2:1. The smaller part will be used to make the tank, the larger one will become the afterburner.

The operating principle of such a furnace system is as follows:

oil is poured into the fuel bunker and set on fire;
air is supplied into the chamber through an air throttle and thus greatly limits the combustion intensity;
as a result, the fuel does not burn, but evaporates, that is, the process of pyrolysis begins;
oil "steam" rises into upper chamber and already there it completely burns out.

In other words, the fuel is used twice - first the oil burns, and then its vapor burns out. As a result, no waste remains, and the efficiency of such a furnace is as high as possible - 80%.

Waste oil is a heavy, heavily contaminated and poorly burning mass of complex composition. Two-stage combustion allows you to fully use the entire resource of this fuel. The structure is located vertically.

On top of it you can install a grid-stand for placing buckets, pots and other utensils.

Drawings that must be strictly adhered to and training videos will help you make a furnace using a cylinder.

The disadvantage of liquid fuel stoves is increased safety requirements. Fuel reserves have to be stored away from the boiler room.

A design that runs on waste oil cannot be used as a sauna stove, but it is useful for heating workshops, cabins and residential premises.

In the latter case, it is better for her to build a separate boiler room in the form of an extension to the house.

So, now you know how to make any stove from a metal gas cylinder with your own hands.

Having the necessary drawings, an angle grinder and an inverter, you can easily make a mobile and efficient heating device that will help out in winter time when other types of heating are turned off or unavailable.

To make a potbelly stove from a gas cylinder, you don’t need to spend a lot of money An economical stove made from a propane tank won't cost too much. The main thing is to make the right drawings. And the materials for work will be available materials. So old cylinder, metal sheets, fittings and pipes - this is the whole set of necessary products.

A potbelly stove made from a gas boiler allows you to burn heat more slowly, processing all the fuel. In this case, you can control the air supply and the combustion process using a special damper. This increases the efficiency and combustion duration. This is why homemade stoves are used in garages, greenhouses, bathhouses, and workshops.

Using a gas cylinder stove you can easily heat a small garage

Advantages of the oven:

Easy assembly. Construction can be completed quickly and easily.
Independent fuel. The boiler does not require electricity, only solid fuel. In this case, the type of solid fuel does not matter.
Small dimensions allow the structure to be placed in any corner of the house.
Easy to use. The mechanism is simple, wood burns for a long time and does not require constant monitoring.

But to operate the oven you will need good ventilation, otherwise the necessary traction will not arise. The heat capacity of the structure is also not encouraging. This is due to the small area of the boiler.

You can increase the heat capacity by equipping a jacket.

Only dry logs should be used for the stove. The disadvantages include the difficulty of cleaning the structure from soot and ash. But the disadvantages are less than the advantages. At the same time, the equipment of the furnace will not be expensive.

The principle of operation of a potbelly stove made from a gas cylinder using wood

The gas cylinder design is a long-burning system. It consists of three main elements: a firebox, a chimney and a blower. The latter is a special channel, which is located at the bottom of the stove. The blower supplies air to the firebox, controlling combustion. This part is equipped with a door to control the oxygen supply. In addition, soot accumulates in the ash pit.

There is a firebox above the ash pit. This element is used to burn fuel. Air enters the chamber through a grille, which is connected to the blower. The firebox is equipped with a door. This is how firewood is loaded into a potbelly stove.

The furnace is ignited when open doors fireboxes and closed blowers. Unburned parts fall through the grate or fly out through the chimney.

The chimney is an exhaust pipe through which the remaining combustion products exit. A special view is installed in the chimney - a damper. It is used to block the chimney. Thanks to it, you can slow down the combustion process and increase efficiency.

The main principles of operation of a potbelly stove:

The blower transports air into the firebox;
Wood or coal is burned in the loading chamber;
Combustion products are eliminated through the chimney;
You can control the intensity of combustion using a damper;
Firewood is placed into the firebox through a special door in the body of the stove.

You can cut the necessary holes in the gas cylinder using a grinder

The blower and firebox are considered the main elements and are mounted directly in the body of the gas cylinder. The chimney can be placed separately. The principle of operation is quite simple, all that remains is to figure out how to correctly design a potbelly stove.

Types of wood-burning gas cylinder stoves

Potbelly stoves are divided according to the installation method into vertical and horizontal. Each type has its own installation features, advantages and disadvantages. It is important to study each option in detail.

The nuances of installing a horizontal furnace:

The construction of such a potbelly stove requires less time;
The oven is installed on metal sheet to avoid fire hazards.

The vertical design is compact. It can be placed in a corner and will not take up much space. The cylinder is installed with the tap down, so the design has its own differences. The door of a vertical potbelly stove is located at the bottom. Less steel will be required for the substrate equipment.

Do-it-yourself stove from a gas cylinder: preparatory work

To create a wood-burning stove from a metal cylinder, you will need to use welding. That is why you should choose a room for work in advance. This should be a well-ventilated room with reliable wiring and constant access to electricity.

You should immediately prepare all the tools for work. You will need a welding machine and a grinder.

The gas cylinder stove should be installed in such a way that it does not come into contact with the lining of the room

The process of making a potbelly stove can last several days. It will be better if the room has a roof. Good sound insulation is welcome, because during work it can be noisy, and this will not please the neighbors.

Materials for creating a potbelly stove:

Frame. Can be made from an old propane boiler. It is best to choose a large 50 liter cylinder.
In some cases, the stove may be equipped with legs. For this purpose, sections of pipe, fittings, and metal profiles are suitable.
Using scraps of rebar you can make potbelly stove handles. A similar handle will be located on the firebox lid.
You can make the door yourself or buy a ready-made one from cast material. The stove will require 2 doors: for the firebox and for the vent. The first one should be bigger.

Separately, it is worth taking time to prepare the cylinder. First, you will need to bleed the propane from the tank. The operation is performed on outdoors. Open the supply tap and wait until the hissing stops.

Next you will need to rinse the bottle. The main thing is to get rid of unpleasant odor, which is used by the supplier to determine leakage. Bleach is used for washing, and then the structure is washed with water.

Do-it-yourself potbelly stove from a gas cylinder: installation technology

First, prepare the container for the oven. You should take a 50 liter cylinder. After this, you will need to decide on the design of the potbelly stove: vertical and horizontal.

How to make a horizontal oven:

First, the top part with the tap is cut off from the cylinder.
4 legs are welded onto the container. The housing must be placed horizontally.
A chimney opening is equipped in the upper part of the cylinder. A bent collar made of steel braid measuring 5 cm is welded onto the round hole.
In internal space install the grate at a distance of a fourth of its diameter. To do this, holes are drilled in the wall of the cylinder.
Next, a hole is made for the door and a nut with a ball valve is welded.

The finished stove is mounted in a garage or other room on a special steel sheet. There should be enough material to occupy a space 50 cm more from the door. The vertical design has its own characteristics, but the preparatory work is the same.

Before installing a potbelly stove from a gas cylinder, you should watch the training video

The hole for the valve in vertical ovens is made 10 cm larger. Next, a collar is installed on the chimney. The blower is installed at a distance of 5-10 cm from the bottom. A firebox is installed above. Grates are installed between the loading hopper and the blower. Finally, install the handles on the doors.

Chimney equipment for a gas cylinder boiler

To operate the stove you will need to have good draft. To do this, the chimney is mounted at a certain height. This place is located above the edge of the grate. You will also need to equip a place to collect moisture. You will also need to remove heat from the chimney.

Heat removal methods:

Install the horizontal section, maintaining a slope of 35 degrees. Next, the chimney will need to be turned up and brought out into the street. A heat exchanger is installed on the channel.
Warm air can be carried by a pipe that exits the oven at an angle. This increases the efficiency indicator and combustion duration.

By equipping a water jacket on the stove, you can significantly increase beneficial properties designs. All features and nuances of installation can be seen in special drawings. In this case, the heat exchanger can be equipped on the housing.

Water circulation in the jacket occurs in a forced manner using a pump.

In this case, the diameter of the heat exchanger must be larger than the diameter of the chimney. The open ends of the pipes will have to be welded. When water passes through the shirt, it heats up and transfers heat to the room.

How to make a stove from a gas cylinder (video)

A stove made from an oxygen or gas cylinder is quite simple design. You can assemble such a potbelly stove on your own. The main thing is to stock up welding machine and Bulgarian. The installation should be carried out based on calculations and drawings.

Examples of a potbelly stove made from gas cylinders (photo)

In many private households there is an old liquefied gas cylinder. From this object you can make many useful things, for example, a simple heating device.

If you have the desire and a welding machine, then you can make a potbelly stove from a gas cylinder with your own hands without special problems. Of course you'll need some additional materials.

A potbelly stove is a primitive version of a metal stove. This device works extremely simply: firewood is placed in the firebox, it burns, the stove 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 flammable materials: diesel fuel, coal, peat, household waste etc. If desired, you can cook quite successfully on such a stove. This point should be considered even before the start of manufacturing the structure in order to make an even hob.

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

For the potbelly stove you need to choose a special place, decorated with fire-resistant materials. It is advisable for it to stand to the side, where no one will accidentally touch the body and get burned.

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

Weighs like this metal structure quite a lot, so we are not talking about any mobility of the device. Move the potbelly stove for heating different rooms it will be difficult.

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

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

Another problem is low efficiency, since part of the thermal energy during the combustion of wood literally flies out into the chimney. There are various ways keep warm and slightly modify the stove 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 body, the role of which is usually “invited” to be an old gas cylinder. It is necessary to make two doors in the case: large and small. The first serves to load fuel, the second is needed as a blower, through which air enters from the combustion chamber to ensure the combustion process and draft.

To begin with, it is recommended to open the cylinder and vent the remaining gas. Of course, this needs to be done outdoors, not indoors. Then you need to drain the remaining liquid that has condensed inside from the cylinder. This substance usually has a strong and unpleasant odor, so it is best to prepare a small container with a lid for it in advance so that you can immediately carefully pack it and throw it away.

There are no particularly strict parameters requirements for the design of a potbelly stove. The larger the combustion chamber, the more spacious the room the unit can heat.

If condensation is accidentally spilled on the floor in a room, the specific aroma can persist for a very long time. After all these operations, the cylinder is still not ready for contact with the welding machine, because residual gas vapor remains inside.

You need to fill the balloon with water to the very top in order to completely displace all the gas from it. After this, the water is drained, now the cylinder can be cut without problems.

Stage No. 2 – manufacturing and filling the case

You can heat all kinds of technical premises, private garages, and small auto repair shops using various units. If desired, you can actually make the simplest design for heating non-residential objects yourself, using an old gas cylinder.

Gas cylinder stove - simple and effective

Nowadays, non-standard heating devices made by hand are used by many home craftsmen. One of the most interesting, easy to manufacture, reliable and cheap to operate is a homemade unit that uses waste oil as fuel. It can be built literally in a couple of hours from a gas cylinder. This boiler has a simple design and operating principle.

The exhaust stove, constructed from a gas cylinder, has two compartments. They burn fuel. Moreover, this process is performed twice. First, direct combustion of waste oil is observed (in the first compartment). This leads to the appearance of flammable mixture vapors. They go to the second compartment of the homemade boiler. There they combine with air, resulting in a highly concentrated flammable composition. When it is burned, a huge amount of heat is generated, which can heat a fairly large area of the room.

Gas cylinder units have many advantages. The cost of their assembly and operation is minimal. You can use any old gas cylinder that has been lying around somewhere in the garage for decades. And it’s easy to purchase the work at the nearest car service center. It costs a penny. The main thing here is not to use overly contaminated oil, since in this case the indicator useful action the stove will decrease, and the complexity of its maintenance (cleaning) will increase.

Other advantages of waste boilers:

Trouble-free design. In the finished unit, in fact, there is nothing to break.
Full autonomy. No need to connect the oven to electrical network or other energy sources.
Low fuel consumption. A unit made from a 50-liter cylinder consumes no more than 2 liters of waste oil per hour.
No soot, no burning, no unpleasant odor during operation of the device.
Versatility. The stoves we are interested in are suitable for any non-residential premises, be it a car garage, a utility or industrial premises, a private greenhouse or a greenhouse.

It is also important that the stove from the cylinder stops working immediately after the fuel is burned (the supply to the combustion compartment is stopped).

Disadvantages of units during development - important to know!

We talked in detail about the advantages of using homemade boilers that operate on waste oil. Let’s not forget to talk about the disadvantages of such structures. First of all, they are considered a fire hazard. Cylinder stoves have open holes through which fire can spread throughout the heated object in a matter of seconds. This fact necessitates constant monitoring of the unit’s operation. Throwing it unattended when the waste is fed into the furnace is strictly prohibited.

The next disadvantage of the design is objectively strong noise. The unit is really loud. Not every person is ready to endure such inconveniences. Also, after each use of the stove, its combustion chambers must be cleaned. A similar procedure must be performed with the chimney. It is an essential part of a homemade waste oil boiler. The chimney, by the way, has to be made quite high (at least 4 m). If you build a smaller smoke duct, there is a risk of poisoning carbon monoxide increases several times.

Oil intended for combustion in a furnace must be stored in special conditions. It must not be left under sun rays. It is also prohibited to store it in negative temperatures. The mining freezes even with minor minuses and becomes absolutely useless. Once defrosted, it cannot be used as fuel.

Another serious drawback of the described stoves is associated with oil. The waste must be cleaned. If you use unrefined oil, the unit's nozzles will quickly become clogged. This may well cause the cylinder to explode. Some home craftsmen say that their homemade heating boilers work on untreated waste. Perhaps the unit will be able to heat the room using such oil. But the effectiveness of its work, believe me, will be minimal.

Elements of a simple homemade stove - what will we make it from?

All the drawings that can be used for testing are approximately the same. Below we show a diagram of a simple heating unit. It is on this basis that we will make a homemade device.

The drawing shows all the elements of our boiler. The basis of the design is a gas cylinder (position 1). The oven is also supplied with:

Perforated pipe (2). It functions as a device for removing combustion gases. The thickness of the pipe walls should be 4–5 mm, the cross-section should be 10 cm.
Another steel pipe (3) with the parameters indicated above. It plays the role of a heat exchanger.
A steel sheet (4), which serves as a partition between two compartments of the structure (in one the oil burns, in the second it evaporates).
Metal visor (5). It is best to make it from 4 mm thick steel. The visor provides maximum efficiency pipe heating.
Evaporator bowl (6). This element is easiest to make from a brake disc from any passenger car.
Half-inch water pipe(8). It supplies used oil to the combustion chamber. This process is controlled by a plumbing ball valve (9), used as a valve.
Oil tank (11). It is a special container for storing fuel. It is advisable to fit any unnecessary cylinder that is equipped with a built-in needle valve under the tank.

The furnace design also includes duct fan(13), connecting element - coupling (7), air swirler (12), welded from equal-angle angles (flange width - 5 cm) and a device for supplying fuel (10). As the latter, it is allowed to use a suitable (flexible) pipe made of fire-resistant material or a durable hose.

We build a boiler from a 50 liter cylinder - any craftsman can do it!

We prepare all the necessary parts and begin assembling the stove for testing. Before starting the main work, you should completely empty the cylinder of condensate and gas residues in it. Advice. It is easy to check the quality of the work performed. Coat the valve outlet (the hole at the end) with concentrated dishwashing liquid or regular soap. Open the faucet. If there is no condensate or gas left in the cylinder, foam bubbles will not appear at the outlet. This means you did everything right.

We remove the valve from the cylinder. If you have a gas container with a non-removable tap, you will have to tinker. Use an electric drill to drill a hole in the bottom. And then unscrew the valve. Pay attention! Experts advise performing this operation very carefully. Even if you are sure that all the flammable composition has left the cylinder, there is still some possibility of the container exploding. Do not press down on the power tool with excessive force. Better yet, water the drill ordinary water in the process of making a hole in the bottom. Then the risk of explosion will be zero. After dismantling the valve, fill the cylinder with water to the top and wait a couple of minutes until it all comes out.

Now we cut out two windows on the gas cylinder. The height of the first (lower) is 20 cm, the second (upper) is 40. The width of the openings is a third of the cross-section of the cylinder used. There should be a jumper between the cut windows. Its height is 5–7 cm. We have a full-fledged compartment for burning fuel. By the way, you can even put coal and firewood in it if you wish.

The next step is to make a device that will separate the heat exchanger from the oil combustion chamber. We will make the separator from a steel sheet 4 mm thick. We cut out a circle from it with a diameter corresponding to the cross-section of a 50-liter gas container. That's not all. In the central part of the completed workpiece, we again cut out a circle (necessary for installing the burner). Its diameter is 10 cm.

The burner itself is made from a pipe with a height of 20 and a cross-section of 10 mm. IN finished product it will be necessary to make perforation - drill several 1.5–2 cm holes. All burrs must be removed from the latter. If cleaning is not done, soot will constantly settle on the holes during operation of the stove. This will cause a narrowing of their cross-section, which over time will lead to a significant decrease in the efficiency of the home-made heating unit.

We put a membrane on the burner made according to all the rules. Weld the last one strictly in the center. Then install the entire workpiece into the cylinder and securely connect it by welding around the perimeter. Advice. The pipe can be welded to the bottom of the chamber divider. Then it will be possible to load special pellets and briquettes, as well as sawdust and other solid fuels into the stove.

The second part of the work - we bring the heating device to mind

We make the evaporator bowl from a brake disc or from any metal product with high heat resistance. Choose a material that is not afraid of elevated temperatures and sudden changes. After this, weld the lid and bottom. Do not forget to leave an opening into which the mining will be poured. It is advisable to improve this part of the oven a little. Simplifying the fuel filling process is easy. It is enough to weld a low tube to the lid at a 40-degree angle, and then cut off the end of the pipe to get a kind of spout. It will be much easier to fill through it.

If you install a ball valve on the pipe, the unit will become much safer to operate. If any problems arise with the tank, you can quickly shut off the supply of used oil.

We construct the heat exchanger from a 10-centimeter pipe. We place it clearly horizontally in the body of the heating device. It is recommended to additionally mount a metal screen at the end of the heat exchanger (we weld a sheet of steel to the pipe). Due to this device, the heating rate of the system and its beneficial effect will significantly increase.

The oven is ready. You just need to connect the chimney to it. We take a pipe 4–6 m long. In its lower part we cut a hole with a cross-section of about 6 cm. We weld a piece (2–2.5 m) of another pipe to it. It is parallel to the floor surface. All that remains is to weld the vertical part of the chimney, mounted outside the room, to a short pipe.

Advice. Make another 6–7 cm hole on the short chimney pipe and cover it metal plate. This simple device will allow you to adjust the intensity with which air will enter the oven. And this, in turn, will make it possible to regulate the combustion rate of the waste. We also need to weld the iron legs to the bottom of the stove we made. They are easy to make from metal corners.

Features of operating cylinder furnaces during mining – safety first!

We have already noted that the structure we are interested in, used for heating non-residential objects, belongs to the group of fire hazardous equipment. If you do not want to encounter serious problems when using a homemade boiler during mining, adhere to the following rules:

There should be no drafts in the room where the unit is located. Wind freely moving around the object can cause fire to escape from the stove through the existing openings.
A stationary gas cylinder boiler must be installed exclusively on metal slabs, concrete or cement base.
After use, the oven must be cleaned. The cylinder itself should be cleaned after each heating session. Remove soot and soot from the chimney at least once every 5–7 days. If the stove is actively used every day, the smoke exhaust duct also needs to be cleaned daily.
All structures, products, materials, objects that are prone to rapid ignition must be located at a distance of at least 4–5 m from the stove.

Last recommendation. Do not fill the combustion compartment full of used oil. The maximum permissible filling of this chamber is 2/3 of its volume. If used correctly, the exhaust unit, made from a gas cylinder, will serve you for a long time and efficiently.
