Oil furnace from a gas cylinder drawings. Types of homemade structures

Do-it-yourself furnace for working out can be made different ways. It's great for heating. technical premises such as workshops or a garage. With a successful choice of model and its correct assembly, this heater will not only become a good heater, but will also help to warm water for making tea, washing hands or other technical needs.

These work areas do not always have a place to store firewood or other fuels, but used fuels and lubricants, such as gear and engine oil, usually found in excess.

Waste oils are most often sent for recycling, so you can always get them almost for nothing, saving on electricity or buying firewood. The heat transfer from the burned mining can be called equivalent to the heat from electric heater, and fuel consumption is from half to two liters per hour.

This method of heating has many advantages, but there are also disadvantages. Information about them will help you figure out what you need to pay attention to. Special attention during the manufacture and operation of the furnace.

The advantages of waste oil furnaces include the following points:

• Such stoves heat closed spaces well, so they are suitable not only for technical rooms, but also for heating small greenhouses and agricultural buildings where pets and birds are kept.
• A properly arranged oven does not smoke and does not a large number burning
• Such a heater is very easy to operate;
• Since the working itself does not burn, but only its vapors burn out, then bake can be called quite fireproof, subject to the rules of its operation.

The disadvantages of this heating method include:

• It is impossible to use mining with foreign impurities in the furnace - it is explosive. At best, the waste from burning such fuel will quickly clog the filter and nozzles, so it should be filtered before use, but filtered oil can also be purchased.
• The chimney, as well as the stove itself, quite often require cleaning from combustion products;
• In the process of its intensive burning, the stove buzzes quite strongly.

Types of furnaces working at mining

Waste oil furnaces can be made, or a pyrolysis unit or a furnace with turbo burners, since they work on the same principle of burning the emitted fumes.

In this case, in the vacuum chamber of the furnace, with a lack of oxygen, the mining is heated, and its decomposition occurs. In the process of decomposition, vapors are released, which rise into another chamber, where oxygen is already intensively supplied. There, the vapors burn, giving off a lot of heat.

The convenience of using this type of furnace is that the intensity of combustion can be changed by increasing or decreasing the supply of oxygen to the pyrolysis chamber.

The disadvantage of using mining in such pyrolysis units is rapid pollution chambers and chimney products of combustion. In addition, with this type of heating it is impossible to maintain the temperature automatically, so you need to keep the stove under constant control.

They independently make similar devices that work on waste raw materials from gas or oxygen cylinders of a large or small size, pipes of various diameters or metal sheets. The design of the unit for testing can be with a drip fuel system or with blowing.

A mining furnace made from a gas cylinder

Oxygen cylinders or natural gas great for making a stove using waste raw materials. They have the desired shape, and the thickness of the metal will allow you to use the device for a very long time.

A stove made from a balloon standard size, will allow to heat a room of 70 ÷ 85 sq. m., and besides this, having somewhat improved the design, it will be possible to use such a device for the water heating circuit. Such an oven does not require installation turbo burners for forced oxygen supply. Mining enters it by gravity.

In order to make such a furnace, you must have the following materials:

• A gas cylinder of 50 liters with walls no more than one and a half centimeters thick. If you take a container with thicker walls, the effect of rapid heating and timely evaporation of mining vapors disappears. The oil boils at 280 ÷ 300 degrees Celsius, while the temperature in the combustion chamber rises to 550-600 degrees.
• Metal sheets for the manufacture of fuel tanks
• Chimney pipes with a wall thickness of two to three millimeters, a certain diameter.
• Pipes intended for the burner device.
• Steel corners.

Of the tools you will need a welding machine, drill, angle grinder machine - "Bulgarian", roulette, building level, another common locksmith tool.

Manufacturing process

The manufacturing process of the unit begins with the preparation of the gas cylinder itself. This must be done to get rid of residual gas and odorant odor.

• The accumulated condensate is drained from the cylinder, and the container is thoroughly washed with water in several stages. The whole process must be carried out on the street.
• Next, the container is installed vertically and filled to the very top with water. For stability, the balloon is buried halfway into the ground or installed in a narrow pallet that has a lot of weight.
• Then marks are made for an even cut of the top of the balloon.
• The upper part of the cylinder capacity is cut with a grinder, and, naturally, water begins to flow out of it. You need to wait until it drains to the level of the notch, and then cut off the top completely.

The cut part will then become the cap of the fuel tank, and Bottom part balloon will warm the room. Now the water from the cylinder can be drained completely.

• It is better to raise the cylinder from the floor, so it is necessary to weld legs from a steel angle to its lower part, they should be about 200 ÷ 250 mm high.
• Next, the cut-off balloon is installed on the legs, and at a distance of 70 ÷ 100 mm from the top, it is cut out by welding round hole for chimney. The hole must have the same diameter as the 400 mm length prepared for this purpose.

This pipe is installed and welded into the cut hole. The welding seam must be even and tight.

• Then, to horizontal pipe a vertical section with a height of 3.5 is welded — 4 meters with the transition to the vertical with the help of a branch. The chimney is then led outside.
• A square hole is cut out at the bottom of the balloon, which will serve as a blower. A door is installed on it, which will help regulate the amount of air supplied.
• The next step is to make a container for fuel, which will be installed at the bottom of the cylinder. It is usually made from a piece of pipe, 70 ÷ 100 mm high and 140 mm in diameter. This pipe is hermetically sealed from below.
• The lid for the resulting container is cut out of sheet of metal, and in it immediately two holes are cut from above:

- one in the center with a diameter of 100 — 110 mm - a pipe of the same size will be welded to it;

- the second - closer to the edge of the circle. Its diameter will be 50 ÷ 70 mm, a movable cover is fixed on it. Through this hole, fuel will be added to the tank and the air supply will be regulated.

• Then in a pipe, tall equal height cylinder and a diameter of 100 — 110 mm, one end is welded round metal blank, equal in diameter to the size of the balloon. The lower end of the pipe is welded into the fuel tank. It turns out a design resembling a barbell.

• Five rows of seven 10 mm holes are drilled. They should be distributed over 400 mm of the height of the lower part of the pipe of the resulting "rod".
• Next, the resulting design is installed inside the prepared cylinder. From above, the cover is welded to its walls.
• Now you can pour into the lower container and test - this process is best done outdoors. If it is successful, you can bring the stove into the room and take the chimney outside.

In the first scheme, the elements of the furnace in mining are located a little differently, and the installation her more complex, but the effect of using the aggregate will be the same.

Another version of the stove for working out from a cylinder - with a water tank

Another version of the furnace for working out, which can heat the room, heat the water, and when the circuit is connected to become, is well suited for use in greenhouses and incubators.

Video: Working stove with an additional water circuit

The work is carried out in the same sequence as in the manufacture of the first model, but with some deviations, since in this case, it is necessary to make a sealed water container. It is located in the upper part of the cylinder, and a heated pipe will pass through it, according to the principle of a samovar, giving off heat to the water that will flow into the heating system or to the draw-off points.

There are other models of spent fuel units made using a gas cylinder. You can come up with your own design, knowing the principle of operation of this furnace.

Furnace on mining, made of sheet metal

More widespread and a popular model of the unit for testing is a design made of metal sheets. There is a completely logical explanation for this: firstly, it is compact, secondly, its weight is only 25-30 kg, and thirdly, the advantage is the presence of a kind hob, which will help not only warm the water, but also allow you to cook simple food.

It should be noted that there are several types of furnaces that differ in appearance, but they work on the same principle.

In order to make these models of furnaces, the same tools are needed as for the cylinder unit, but the materials are somewhat different:

- steel sheets having a thickness of four and six millimeters;

- segments of a steel pipe with a wall thickness of 4 mm, a diameter of 352 mm - a length of 60 and 100 mm, and a diameter of 344 mm, a length of 115 mm.

- a pipe with a diameter of 100 mm and a wall thickness of 4 ÷ 5 mm, a length of 500 mm.

— metal corner 30×30, length 800 ÷ 900 mm;

- steel strip with a thickness of 3 ÷ 4 mm.

Having prepared materials and tools, you can proceed to the next stages of work.

The process of manufacturing parts and their installation

The first thing to do is to draw up a design drawing of the furnace. You can develop it yourself, or you can use ready-made making additions, if necessary,

• For the container where mining will be poured, a piece of pipe (Ø 344) is cut off with the help of a grinder, in this case, 115 mm high.

- For its bottom, a circle is cut out of a metal sheet using a welding machine.

- Details of the legs are cut from the corner.

- When everything for the manufacture of the container is ready, you need to immediately assemble this element of the stove using electric welding.

• Next, you need to make one more detail - this is a lid that will cover the waste oil container.

- For this, a pipe segment Ø 352 mm, 60 mm high is used. A cover is being prepared for him. To do this, a circle with the same diameter is cut out of a metal sheet.

- In the center of this metal cover, a hole with a diameter of 100 mm is marked and cut out - according to the diameter of the pipe, which will be welded to it later.

- Closer to the edge, you need to cut another round hole with a diameter of 60 mm. Through this neck, mining will be poured into the container, and the furnace will be ignited.

— This hole is closed with a movable cover. It is also cut out of a metal sheet, installed on the surface of the lid, making it movable - turning on the axis. For ease of opening and closing, a small handle is welded to the moving part. This cover will help regulate the flow of air into the fuel tank, and the intensity of combustion will depend on this.

The finished design is tightly put on a previously prepared container for testing. This assembly is collapsible so that it is possible to regularly clean the heater.

• Next, a piece of pipe with a diameter of 100 mm and a height of 360 mm is cut off. Six rows of holes are drilled in this pipe, eight in each, with a diameter of 10 mm. This pipe is welded into the finished lid of the lower tank.
• The next step is to make the upper part of the stove.

It will require:

- Pipe section Ø 352 mm, height 100 mm;

- Two round blanks from a metal sheet of the same diameter;

— Metal plate for internal partition, 70 cm high and 330 mm long. This part is installed in order for the heat to linger inside the stove for a longer period, without immediately leaving for chimney pipe.

- Holes Ø 100 mm are cut out in both round blanks, into which pipes will be welded - into one of them a pipe coming from below, with small holes, and into the other - a chimney. Holes are cut eccentrically - their center is 110 mm from the center of the workpiece

- The top cover is welded to the pipe section - the body. Immediately after this, it is necessary to weld the partition - it shifts as much as possible towards the chimney and boils to the lid itself and to the walls of the cylinder.

- Now you can weld the bottom cover. Its hole should be located diametrically opposite the hole on the top cover.

- A chimney pipe with a diameter of 100 mm and a length of 130 mm is welded to the top cover.

- Then assembled knot is joined by welding with a vertical perforated pipe.

• The last step is the installation of a chimney pipe, and, if necessary, supports from a metal strip for or for the stove itself.
• All welded joints must be absolutely tight.

If it is not possible to find pipes of large diameter, then the upper and lower nodes can be made box-shaped by welding them from a steel sheet 4 mm thick. Only the appearance of the stove will change a little, but this will not affect the principle of its design and operation.

There are others They may differ in their appearance, the location of the heating surfaces, the methods of supplying fuel and the volumes of containers for it, but the principle of operation of the units remains the same.

Safety measures for the operation of furnaces in mining

When using a stove that uses mining as fuel, certain safety measures must be observed, since their flame is quite open.

• The unit must be installed on a non-combustible surface. The walls around the stove should also be finished with heat-resistant material.
• It is impossible to install a heater of this design in a draft, as it can spread the fire to combustible objects.
• It is strictly forbidden to place flammable objects near the oven.
• For the furnace it is necessary to use only waste oil purified from impurities.
• Do not add fuel during intense combustion.
• When the furnace is ignited, the container must be two-thirds full of mining. A little thinner or gasoline is added on top of the oil to start burning, heat up the oil and start evaporating.
• The stove is set on fire with a wick or paper folded into a long tube, directing the fire into the hole for pouring fuel.

Video: operating instructions for an oil mining stove

Having the skills to work with welding machine and others necessary tools, if desired and the availability of materials, it will not be difficult to make such a stove. If it is necessary to carry out work in the cold season in the garage or workshop, there will always be an opportunity to warm up near the fire. In the spring, when the weather is still unstable, and the seedlings have already been planted in greenhouses, a cheap fuel stove will help maintain the desired temperature in the room. You can find application for this heating unit in other circumstances when you need to quickly heat a technical or utility room. Therefore, if one is available, then it is simply necessary to have a similar heating device on the farm.

Sometimes you can’t do without heating a garage or other utility room. But how to organize it - this question for the majority becomes insoluble. Installation solid fuel stoves is simple, however, they require the purchase of firewood, coal, which is a problem in regions where there are no forests. It is much easier to negotiate with a car service, to purchase a used machine oil for a pittance or even for nothing - after all, recycling also costs money. Masters will gladly agree to give this fuel, subject to self-delivery. Today we’ll talk about do-it-yourself stoves for working out. We will provide drawings, video instructions, which means that the reader will easily understand everything.

Read in the article:

What is mining, and how to use it in heating

Working off is called engine oil, which has served its time in a car engine and must be replaced. It is drained, changed to fresh, and the old must be disposed of in specialized services - after all, you cannot pour it out into the street.

A little help! If mining or other fuels and lubricants are spilled on the ground, all the grass dries up in this place, and the “dead” black spot will "pleasing to the eye" for another 5-10 years.

Waste motor oil is used in heating systems as a coolant, however, for utility rooms there is an easier option that does not require high costs for the installation of highways and the installation of the boiler. This is about homemade stove in mining, in which oil is used as fuel. It may seem that it is difficult to make such a unit, however, this is a delusion. The issue is being solved by modernization - the insert is mounted on the working out for the stove. This work is within the power of even a master who has never encountered such structures. But first things first.

The principle of operation of the stove at work

It is clear that if you just light the oil, the room will instantly fill with acrid smoke, and it will not be possible to stay in it. This question is solved by the insertion - a perforated pipe. Let's look at the principle of operation of the unit.

In simple terms, a second chamber is added to the combustion chamber of a conventional furnace, which is connected to the first pipe section. The oil poured into the first chamber ignites, but at the same time, the soot (in fact, unburned fuel, which gives the main heat) has nowhere to go, and it rushes through the perforated pipe into the second chamber (wood-burning stove). Through the holes, the mixture is saturated with oxygen, which allows it to burn. As a result, intense combustion occurs inside the pipe, passing into the second chamber, and the remaining soot is removed to the street through the chimney.

But understanding the principle of work is still half the battle. In order to understand how to make a furnace for working out, you need to take into account many nuances, know the layout of the unit. In addition, the heating devices themselves can be various types. Let's try to deal with this issue.

Types of stoves on used engine oil

Among the total mass of such units, there are 3 main types:

• stoves open type;
• closed (drip) type;
• pressurized devices.

The main thing now is for the reader to understand what design features each of these species has, and what advantages and disadvantages they have. Let's analyze each of them in detail.

Open-type stove-stove: its features and disadvantages

We talked about the simplicity of the oil-burning stove-stove. The cost will also be quite low. Autonomy can be called another advantage - its operation does not depend on the presence or absence of electricity. But ... probably, this is where the advantages of this species end. But there are much more negative qualities. Among them:

1. At the slightest deterioration in draft in the chimney, the stove will begin to smoke inside the room, and the flame will die out.
2. Any liquid that gets into the oil will cause the burning fuel to spray through the afterburner holes. The result is predictable. For this reason, mining should be prepared before being poured into a container, filtering out water or other liquids.
3. Low efficiency with high fuel consumption.
4. The body of the unit is difficult to clean from soot.

However, some shortcomings can be removed if some design tricks are applied.

Furnaces for mining closed drip type and their features

This type has cardinal design differences from the previous one. The perforated afterburner is placed not outside, but inside the tank. It can be a container welded from a pipe, iron sheets or even a gas cylinder. This provides a higher fire safety. A bowl is placed under the afterburner, on the bottom of which drops of oil fall. This ensures low mining consumption and increased efficiency.

minus similar design can be called the complexity of its assembly. The fact is that it is unlikely that it will be possible to assemble such a unit according to other people's drawings, observing ideal proportions. In any case, some modifications will be needed during operation.

Supercharged working furnace: manufacturing nuances

The principle of operation of a do-it-yourself waste oil furnace with a boost is not much different from the previous version. A feature is that the design includes a fan that provides forced air supply. Also included in the circuit check valve, which excludes the ingress of combustion products into the room in the event of a fan shutdown.

Good to know! Such a unit is characterized by lower fuel consumption with greater heat transfer. The negative quality of the heater for working out with forced ventilation is energy dependence. When the fan is turned off, the draft drops sharply.

Materials for the manufacture of waste oil heaters

The main material for making a furnace in a mining garage is metal, although some argue that it is convenient to use an asbestos-cement pipe as a perforated afterburner. However, practice shows that similar material short-lived, and therefore, its use is unprofitable.

The most common option is an oil stove for mining, made from a gas cylinder, but it cannot be said that the design of pipes of various diameters is complex. The main task here is correct calculation pipe sections for both the reservoir, the perforated afterburner, and the blower. With any discrepancy, the unit will work unstably. That is why experienced home craftsmen say that such a used oil heater will have to be redone several times, bringing it to perfection, even if it is made according to clear drawings.

Expert opinion

HVAC design engineer (heating, ventilation and air conditioning) LLC "ASP North-West"

"On the correct work such units are affected not only by a clear calculation of proportions, but also by air humidity, and even by the height of the location. This should be taken into account during production.

Positive and negative qualities of various types of furnaces in development

Regardless of the type of stove, they all have both positive and negative qualities. Let's consider them in more detail.

The advantages of such devices include:

• good heating of enclosed spaces, which include garages, greenhouses, household buildings;
• non-volatility (in case of installation of a furnace without pressurization);
• simple operation;
• small dimensions, allowing transportation of the unit;
• low cost of fuel;
• the possibility of cooking;
• no open flame.

However, such stoves also have a lot of disadvantages:

• the need to filter used oil;
• a chimney that requires frequent cleaning must be at least 4 m;
• hot surfaces are very dangerous;
• specific smell of used oil;
• the inability to extinguish the flame, up to the complete burnout of the fuel;
• fire hazard in case of improper operation;
• noticeable hum during operation.

If, in the process of comparing the advantages and disadvantages, the first category is more significant, then such an aggregate is exactly suitable for a home master.

How to make a stove for working out with your own hands: some tips and step-by-step instructions

As already mentioned, the manufacture of such a unit cannot be called difficult, however, in any, even the simplest work, there are some nuances. Now let's try to disassemble the production the simplest stove drip type from a gas bottle. For this you will need:

• directly myself gas cylinder;
• pipe with a diameter of 100 mm (2 m);
• corner 5 × 5 cm (about 1 m);
• steel sheet, 4 mm thick (about 50 cm 2);
• car brake disc;
• oil-resistant rubber hose and clamps for it.

Having prepared everything necessary details you can start making.

Making a do-it-yourself drip-type stove: step by step instructions

For the convenience of the reader, we will issue step by step instructions in tabular form.

Illustration	Action to take
	First of all, you need to drill a hole in the bottom of the cylinder to let out the remaining gas. To prevent sparks, the drill must be moistened with oil. Drill speed should be as low as possible.
	Now, with the help of a grinder, you can cut holes according to a previously prepared drawing (some of them will be presented below).
	From sheet steel we cut out the bottom with a hole. The cut out middle part should not be thrown away - we will need it later.
	Approximately so the bottom will be located in our stove. We try it on and pull it out again - there is still some work to be done with it.
	The next step is pipe preparation. We drill holes in it for air supply. This is necessary for normal operation unit.
	This is how the finished bottom is welded with a perforated pipe. Welding seams must be of high quality. If home master no experience with a welding machine, it is better to seek help from professionals.
	And now the middle cut from the bottom will come in handy. It should be welded to the brake disc from the car.
	In the end, this is what happens. Now, having cut a small hole and welded a piece of pipe, we get a full-fledged coupling.
	You can start assembling. Pay attention to the pipe on the right. It is through it that the used oil will flow into the stove.
	Outside, we mount the crane and attach a hose made of oil-resistant rubber to it.
	We weld the rest of the pipe on top of the gas cylinder - this will be the chimney outlet.
	It remains only to bring the chimney pipe out of the room.
	Raise the chimney to the required height. Usually it is 4 m. This is enough to ensure normal natural draft.

Do-it-yourself stove for working out: drawings, video instructions and some tricks

Having understood in general terms, what is the algorithm for performing work, let's move on to the drawings and video instructions. Let's start with the same furnace from a gas cylinder.

Furnace for mining from a gas cylinder: drawings for manufacturing

Consider the drawings of the furnace for working out with your own hands.

Below you can find a video instruction for the manufacture of such a unit.

Video and drawings of waste oil furnace with water circuit

Heaters with a water circuit are a little more difficult to manufacture, however, this work is also within the power of a home craftsman. We suggest that you familiarize yourself with the drawings of such units.

The video below will help you better understand the algorithm of work.

Do-it-yourself boiler for working out: drawings and video instructions for manufacturing

Naturally, the water circuit implies the presence of a boiler. It is about him that we will now talk. Below are the drawings of this design.

And, of course, a video tutorial on making a boiler.

As you can see, the drawings of the burners for working out with your own hands are simple, which means that if you have time, you can try to assemble such a unit. Moreover, it practically does not require any expenses.

Rules for the operation and maintenance of waste oil furnaces

In order for the operation of such units to be safe, the editors of the site recommend that you follow some rules:

1. It is strictly forbidden to allow children to ignite.
2. Do not use flammable liquids such as acetone or gasoline for ignition. Flashing fumes can easily cause burns.
3. You should not use mining with water particles. This will lead to a fire.
4. Add mining until the fuel burns out completely.
5. Use the oven indoors without adequate ventilation.
6. It is forbidden to use the stove if it does not work properly (the unit smokes or its combustion is unstable).

Maintenance of such devices is reduced to periodic cleaning of the combustion chamber from non-combustible residues and cleaning the chimney from soot (at least once a month).

If, for some reason, the home master does not have the opportunity to independently manufacture such a unit, it is quite possible to purchase it in specialized stores or on Internet resources.

At what price can you buy a furnace for mining on the Russian market

Consider at what cost such devices can be purchased. Prices are as of March 2018.

brand, model	Power, kW/h	Fuel consumption, kg/h	Average price (as of March 2018), RUB
	27	4	260 000
	80	7,2	102 000
	11,5	9	680 000
	16−43	1,4−4	70 000
	94	8,7	425 000

As you can see, the cost of factory-made units is quite high. So, it is more profitable to spend a little time and effort by making such a device with your own hands.

Summing up

After reading today's article, someone will say that it is easier to buy a stove with factory-made waste oil. However, the cost of such units is not affordable for everyone. Do-it-yourself production practically does not require costs, which is a huge plus. Of course, you will have to go by trial and error, but in the end, such a stove will not only heat the air in the room. It will also be warm in the soul from the realization that all the work was done independently.

We hope that the information presented today was useful to our esteemed reader. If you have any questions, we will be happy to answer them in the discussions below. We will also be grateful if you share your experience - this will help novice home craftsmen. And finally, we suggest watching a short, but very informative video on the topic, which will help you learn how to properly ignite such units.

Among the options autonomous heating premises, the most interesting can be called a special type of potbelly stove, which uses used oil. Doing it yourself is not difficult, since the design is relatively simple, and the tools and materials necessary for work are quite affordable. During the operation of the unit, special problems also usually do not arise. The main advantage, of course, is savings, because what can be cheaper than used oil?

The principle of operation of such a stove

In such stoves, the combustion process occurs twice, that is, it will be necessary to equip two combustion chambers. In the first chamber, the used oil burns slowly, and combustible vapors are formed. They enter the second chamber, where they mix with air. This gas-combustible mixture burns in the second chamber, and releases a significant amount of heat, heating up to very high temperatures.

In a do-it-yourself waste oil furnace, combustion processes occur at a fairly high temperatures. The unit is considered quite safe, but it is not recommended to put it in a draft

In order for a homemade waste oil stove to work correctly, it is necessary to provide air supply to both the first and second chambers. Where mining is burned, a control damper is needed, since the amount of air entering here should be moderate. To provide air to the second chamber, usually a series of holes about 10 mm in diameter are made in the pipe connecting these two sections.

Autonomous heating can be provided by assembling a waste oil boiler. Detailed guide for installation you will find in our following material: .

Types of homemade structures

According to the type of construction of the furnace, mining can be divided into three types:

• homemade units from sheet metal or gas cylinder;
• supercharged structures;
• drip fuel models.

The first option is a very simple device that craftsmen who have the skills to work with a welding machine make on their own. To do this, use a sufficiently thick sheet metal, metal pipes etc. The use of a gas cylinder can significantly reduce the operating time. There may well be gas residues in an already used cylinder. When cutting off the upper part, there is a danger of a small explosion. To prevent this from happening, it is recommended to pump water into the cylinder and only after that begin dismantling.

For a forced-air oven, you will need to install an additional fan. This is done in such a way that the main air flow falls on the second chamber. This ensures high-quality combustion of the fuel, and also contributes to the uniform and rapid distribution of the resulting heat throughout the room.

Depending on the design, the waste oil furnace can use conventional convection, an air heat exchanger or water heating in a boiler

Making your own drip fuel supply is quite difficult. Typically, industrial models are completed with such an element. This allows you to significantly save the consumption of used oil. Industrial units are efficient, compact, safe and relatively inexpensive. However, there are also homemade models, combining and drip system oil supply, and boost.

You may also find it useful to read an article about the features of arranging heating at work:.

Making a stove from a gas cylinder

Making a sheet metal oven is not difficult. To do this, two combustion chambers are brewed, legs are attached to the bottom. Then they are connected by a pipe with holes, a vertical chimney is mounted on the upper combustion chamber, etc. However, all these operations require rather lengthy welding work. To reduce them, craftsmen successfully use gas cylinders. These containers have sufficiently thick walls to ensure both the fire safety of the structure and long term its operation.

Regardless of whether a cylinder or sheet metal is used to make a furnace, a number of rules should be followed when creating a structure. They need to be taken into account when figuring out how to make a waste oil furnace.

1. The air supply to the first combustion chamber must be made adjustable. For this, a conventional damper is suitable, which can be slightly opened to leave a gap of arbitrary size.
2. The chamber into which waste oil is fed for burning is always made collapsible so that it can be easily cleaned.
3. The chimney must be strictly vertical, horizontal or inclined sections are not allowed.
4. To ensure good draft, the length of the chimney must be at least four meters.

Exist various options the use of a cylinder in the manufacture of a furnace for testing. The simplest one looks like this:

1. From the cylinder you need to cut off the upper and lower parts.
2. From the resulting halves, a collapsible combustion chamber for oil is made.
3. Metal legs are welded to the bottom.
4. A hole is made in the upper part of the first chamber, into which a piece of pipe with an adjusting plate is mounted. Through this opening, a regulated air flow will be supplied, as well as fuel.
5. A hole is also made in the center, to which a pipe segment is welded connecting both combustion chambers.
6. A series of air holes are made in this pipe.
7. A secondary combustion chamber is made from the middle part of the cylinder and sheet metal, which is also welded to the connecting pipe.
8. At the last stage, a chimney is made and installed.

To easily place the oven in the correct position on uneven surface, it is recommended to make legs that can be adjusted in height.

This is the easiest way to use a gas cylinder to create such a heater. The following diagram shows a more complex garage stove for testing. It uses a gas cylinder, while a pressurization system and drip fuel supply are installed.

This is a manufacturing option complex furnace on testing from a gas cylinder, which takes into account the possibility of organizing pressurization, and also a drip fuel supply system is installed

For heating small rooms, you can build a potbelly stove that will last more than one year:.

Although the device is not complex, it is still recommended to follow a number of rules when using it:

1. To prevent oil from splashing out of the combustion chamber, do not fill the tank more than two-thirds.
2. If the hot mining “boils” after ignition, reduce the air supply using the control damper.
3. In order to maintain sufficient draft, both the oil tank and the chimney should be cleaned of dirt weekly.
4. To remove soot, the upper part of the structure must be tapped.

Working furnaces are well-deservedly popular with car owners, as well as at service stations, in small car services, etc. With their help, you can successfully heat small and medium-sized rooms.

Furnace in development - non-standard, but very effective solution for heating technical rooms, car repair shops and garages. This design is designed for fast and economical heating at minimal cost and high efficiency. Considering that industrial premises are rarely insulated, the furnace power must be higher than the standard one, which is calculated using the formula 5 kV / 50 m 2. In our article, you will learn how to make a do-it-yourself furnace for testing: drawings from a gas cylinder, a launch video, the pros and cons of such a design.

If we take into account the complexity of manufacturing and the cost of fuel, a gas cylinder mining furnace is the most budgetary and most effective option. The shape itself helps in many ways - spherical, in fact, an ideal firebox. For any furnace, the presence of two holes is fundamental - the inlet, where the fuel is loaded, and the outlet - where the processed gases come from, and this is easy to do from a ready-made cylinder. Its shape is also suitable because the cylinder holds required pressure while minimizing metal consumption.

1. Gas bottle 50 liters
2. Steel pipe for the removal of burning gases, with perforation, with a diameter of 100 mm and a wall thickness of 3-5 mm.
3. Steel pipe of the heat exchanger, 100 mm in diameter with a wall thickness of up to 3-5 mm.
4. Partition between the evaporation chamber and the combustion chamber, steel sheet 4 mm thick.
5. Canopy over the heat exchanger, increases the heating efficiency of the pipe, steel sheet 4 mm thick.
6. Evaporator bowl, car brake disc can be used.
7. Coupling.
8. Plumbing half-inch pipe for supplying mining to the combustion chamber.
9. The valve that regulates the fuel supply is an ordinary plumbing ball valve.
10. Fuel supply hose, flexible, refractory pipe can be used.
11. Mining storage container, any will do bottle with integrated needle valve.
12. Air flow swirler. Two welded squares with a shelf width of 50 mm are used.
13. Channel fan.

Step by step guide to making

1. Before starting the actual creation heating device, all gas and condensate must be vented. In order to check how empty the cylinder is, smear the outlet on the valve with soap or concentrated detergent- as soon as it stops bubbling, you can proceed.
2. If the valve is removable, carefully remove it. If not, make a hole in the bottom with a drill and twist the valve. At the same time, note that even if all the gas is released, the risk of an explosion still remains. In order to protect yourself, try not to press the drill with force during drilling and constantly pour water on the drill.

1. After the valve is removed, fill the cylinder with water and leave it for a few minutes to completely remove all gas elements.
2. Cut out two holes on the balloon, as shown in the photo. Width - within a third of the diameter of the cylinder. You make the first opening 20 cm high, the second - 40 cm, the jumper between them - at least 5 cm. So you got an improvised combustion chamber, where even solid fuel can be used.

1. Now you need to separate the combustion chamber and heat exchanger. To do this, cut a circle from a 4 mm sheet of metal along the diameter of the cylinder (standard - 2.95 cm). Next, in the center of this circle, cut out another one with a diameter of 10 cm, which is needed for the burner.

1. Burner manufacturing. Take a pipe with a diameter of 10 cm with a wall thickness of 4 mm and a height of 20 cm and drill several holes around the perimeter. The diameter is arbitrary - 1.5-2 cm.

Be sure to deburr all holes. If this is not done, over time, the settling soot will lead to their narrowing and deterioration in the characteristics of the furnace when working out from a propane cylinder.

Put the membrane on the burner and weld it with hot welding exactly in the center.

Insert the workpiece into the cylinder and weld already around the entire perimeter. If the pipe is welded along the lower boundary of the partition, it will be possible to fill the furnace during mining not only with used oil, but also solid fuel- wood chips, briquettes, pellets, etc.

1. Prepare the evaporator bowl. Since we are talking about or a car repair shop, a brake disc is ideal for this purpose.

If this is not at hand, you make a thicket of any heat-resistant metal that will not deform from temperature changes.

1. Weld the bottom and lid, leaving a wide hole where the used oil will be fed. This is a draft version of the furnace, which, however, is the most popular (watch the video).

Video 1 Starting up a waste oil furnace

You can improve the design by welding a pipe to the cover at an angle of up to 40 degrees and cutting it so that you get a “nose”. This is done in order to make it convenient to pour oil.

And if you screw an ordinary ball valve onto the pipe (see photo), then the design will also turn out to be safe. Because it will allow you to shut off the fuel supply in case of problems on the tank.

1. Heat exchanger manufacturing

A pipe with a diameter of 10 cm also acts as a heat exchanger, which enters the body strictly horizontally.

To concentrate hot air, a heat-reflecting screen made of 4 mm metal sheet can be welded to the end of the pipe.

The design of the furnace with a water circuit

This option is an improved model of a home-made furnace for working out from oxygen cylinder, which, if necessary, can even heat a living space. To do this, it will need to be embedded in common system home heating.

There are 2 main methods for organizing a furnace for mining with a water circuit:

• tying the body with a coil;
• making a "shirt" on the burner.

The first way is very simple, economical. But quite effective. As a coil, you can use a conventional copper pipe, which crashes into the heating system of the house in order to ensure the circulation of the coolant.

The second method is more complicated, which involves the manufacture of a separate water jacket, which is subsequently put on the burner itself.

Advantages and disadvantages

Like any heating device, a 5 liter gas cylinder furnace has its pros and cons.

• the simplest scheme that allows you to build a furnace in just a few hours;
• trouble-free simple design, in which there is simply nothing to break and fail;
• stops immediately as soon as the fuel supply stops, cools down relatively quickly;
• independence from energy sources, since the main fuel of the furnace for mining is used oil;
• versatility - such furnaces can be used not only in garages and car repair shops, but also in greenhouses, industrial premises etc.;
• minimum flow fuel - up to 2 liters of waste oil per hour.

• open holes increase the risk of fire several times;
• it is strictly forbidden to leave the oven uncontrolled;
• It is not recommended to use heavily contaminated processing. It is advisable to pass it through the filter or install a separate filter on the inlet;
• minimum height chimney - 400 cm, to eliminate the risk of poisoning with processed gases;
• each time after the operation of the furnace, it and the chimney must be cleaned;
• noisy oven.

Safety

Taking into account the fact that the furnace in mining (oil mining) is extremely flammable, a number of precautionary measures must be observed during operation, namely:

• the stove is installed only on a stationary non-combustible base - a concrete or cement site, tiles, metal sheets;
• when the device is operating, there should be no drafts in the room so that the fire does not break out of the open hole;
• flammable objects should be located at a distance of at least 3-5 meters from the stove.

Operating conditions for the furnace

To start the furnace, it is necessary to pour used oil on the bottom, pour kerosene or diesel fuel on top. Next, set fire to a tourniquet of paper or fabric and stick it into the hole.

It is advisable to clean the oven every time after using the oven. Soot and soot accumulating on metal surfaces, isolate the reflective properties of the metal and significantly reduce the efficiency of the stove.

It is advisable to make a furnace for working out from a gas cylinder with your own hands only if you have such fuel. It is not difficult to find it, since auto repair shops must dispose of used oil. But some "businessmen" even manage to sell such oil. Judging by the prices in the network, the average price per liter of used oil in the region ranges from 5 to 15 rubles.

Today's article is devoted to how to make a furnace from a gas cylinder for working out with your own hands. We will look at exactly how to heat a room using used oil and an old cylinder - there will be a corresponding video and drawings. This method has its own characteristics that everyone must know, but we will talk about this later.

Advantages and disadvantages of "working out"

This method is often used in non-residential premises like garages, workshops, warehouses, etc. Everything works quite simply - first, the mining heats up, after which oil vapors form, which also burn, and much more intense than the liquid fuel itself. As a result, we have a fairly efficient gas cylinder furnace for mining, which is able to heat a small room for a very small amount.

This method of heating a room is very popular in auto repair shops - there is always free oil at hand, which is drained from old cars. In this case, heat is generally obtained free of charge, plus everything, there is no need to look for how to dispose of old oil. The only point is before use it needs to be cleaned so that there there were no impurities.

After reading the list below, you can finally decide whether it is worth it, since there is many nuances associated with both the unit and the type of fuel used in it.

Pros:

The cost of a mining furnace is minimal. If there is no desire to buy, you can make it or sheet metal. There are plenty of drawings and videos on the Internet, even a person with minimal skills will be able to repeat the whole process.

In second place, of course, the price of the fuel itself- if you buy it "ready to use", the price per liter will be no more than 15 rubles. It often sells for 8 to 12 rubles(depending on seasonality and region).

The design and the fuel itself are safe. The cylinder stove gives enough heat, while no bad smell or burning / soot. This is due to the fact that the oil emits vapors when heated, and already when burned, they provide a "supply" of heat to the room.

Minuses:

Do not use used oil that has not been purified in the oven. In this case, the nozzles will quickly become clogged and the balloon may explode in addition, the effectiveness of such an oil is questionable.

Fuel must be stored under certain conditions. At low temperatures, the oil freezes and becomes useless. Imagine you came to the garage, you want to quickly heat it up, and the stove turns out to be completely useless, as the oil has turned into ice.

We make a stove from a gas cylinder with our own hands: drawings and detailed instructions

You can make such a furnace from an oxygen or carbon cylinder. The main advantage is that the walls of the original material are thick (sometimes up to one and a half centimeters). And this means that the equipment will be able to work for a very long time. Even the simplest option from a small cylinder will heat the room without any problems. 70-80 squares.

There is another plus - processing comes by itself. In addition, you do not need to be smart with the creation of an air supply system - this is simply not necessary in this type of furnace.

In order to make a finished oven with our own hands, we need detailed drawings, as well as following tools/materials: a grinder, a file, a drill, a tape measure, a capacity of ~ 10 liters (for fuel), as well as pipes with a thickness of at least 2 mm. and iron corners.

The thickness of the balloon is important due to the fact that the walls will heat up up to 600 degrees Celsius or more. Thin walls can “crumble” from such an impact. The container itself must be thoroughly rinsed with water to get rid of all foreign liquids and odors.

First you need to fix the balloon. But don't do it yourself. It is best to dig it 10-15 centimeters into the ground, and only then start working as a grinder. top cut off (next it will need to make a hole in it), but in no case should we throw it away - it will be used as a “lid”.

We do the same with bottom- cut it off. It will serve as a "camera". We weld iron corners to the lower part, which will serve as legs for the future furnace.

A pipe must be connected to the hole made in the upper part of the cylinder to remove the smoke. Its diameter should be about 10 centimeters, and its length should be at least 4 meters. It is enough to weld the pipe (this can be done after the installation of the furnace itself).

Next, you need to work with this pipe. It is necessary to make 10 holes in it at a small distance from each other. The hole size is about 3 mm. One of the holes should be 5-7 centimeters- we weld a pipe to it with a length of 2 m or more, which is located parallel to the floor (in fact, it departs “sideways” from the vertical one and serves as a chimney).

We will need another hole of a similar diameter on the same pipe in order to regulate the intensity of the air supply. It needs to be covered with a plate.

As you can see, it’s not so difficult to create a finished oven from a cylinder with your own hands, but text instruction is not always enough, so we advise you to carefully study the diagrams and videos before you start acting.
