can afford it. Among the huge number of self-heater and oven-made ones, we mention a rather interesting heater design, such as a waste oil-type furnace. Almost all owners of cars in the garage have a certain amount of oil. For further pouring into the engine, this oil is no longer suitable, but how the fuel for the furnace fits perfectly.

Homemade waste oil ovens: basic types
If you look at the appearance of the stove that works on the stoveSome kind of waste, then such an oven does not cause enthusiasm, but this is only in appearance. Almost all the kilns on the test, which were made independently, were improved several times and modified for more stable work and better heat output. In order to assess and understand the reliability of such a furnace, it is necessary at least once to try to do it by yourself or try the already prepared stove in a severe frost.
Often for yourself they make the simplest and lightest in construction a stove for working, but if you want you can make more difficult.
There are 4 types of complex kiln designs:
- Oven waste furnaces with air blown into the combustion chamber;
- Stove in working area with adjustable heating power;
- Waste oil heater with a water circuit or hot-blown surface of forced type;
- Droplet furnace for working.
Poor evaporation and high viscosity of waste oil significantly increases the fire safety of the stove, but it is still easy to maintain and refill the tank, as well as control over the combustion and evaporation of those gases that are spent.
For making the majority of furnace options, a metal sheet with a thickness of 3 or 4 millimeters, a Bulgarian with spare discs working with metal, a welding machine, and four electrodes will be needed for working.
Furnace for drip-type digging with your own hands
There is an equally interesting design of the stove for working. The design of this type is called: a stove with a fire cup. On the bottom of the cylinder have a small open container with a filler. On the pipe, which is located in an upright position, work-up comes down from the top. Working off, which comes on the heated metal evaporates and decomposes the heavy oil into a lighter one. It burns perfectly, and there is almost no plaque left. The heat output of the burning waste oil is transferred through the furnace body, into the water tank or heat exchanger.
This design of the kiln is difficult and difficult to manufacture by hand. But with such a complex and heavy construction it gives ease of operation, quality of burn-out and has no sensitivity to the quality of the oil.
In case the size of the stove is not important, it will be better to choose a kiln with drip feeder.
How to make a stove for working with blowing
Such a design as a stove for working with inflatable is easy enough to do by yourself. On the first manufacture, it is necessary to cut the blanks from the sheet of metal.
The second stage consists in high-quality welding by welding the material into a finished structure.
To start the manufacture of the furnace, we rotate it on sheet metal and cut out the bulb with 4 bottoms, for the lower and upper chamber of the stove. To process the cut material, you must leave a spare 1mm in diameter for each cut out element. The cut out elements are grinded on the sharpener until it reaches a size, such as the one you selected. The same requirements apply to the side walls of the combustion chamber. For the heat chamber can be used: thick-walled pipes or an old gas cylinder with a thickness of not less than 4 millimeters. Using the core, note the location of the holes and drill them with a drill or, if you have one, on a drilling machine.
The welding machine does not present any work with the correct choice of the electric welding mode.
Before starting to weld the prepared elements it is worth to practice, on scraps of metal.
should be used for the preparation of the stove for working. This training will enable to adjust the normal current and the burning speed of the electrodes.
Further actions will be as follows:
- With the dots, we grab the bottom and the sides that are located on each side, the joint must be welded twice, only in this case we get strength and tightness when welding;
- We perform the installation of the heat chamber and its fixation by welding, then with the help of a soldering lamp we warm up the place of laying the welded seam and weld it also with a double seam;
- We put the lower part of the bottom of the upper chamber on the pipe and perform welding in the same way as in the previous paragraph;
- We weld the side walls and the cover of the upper chamber, the supports, the adapter for the chimney pipe.
For the tank where the lining is being poured, the lid must be removed that is easy to remove, and the lid must fit snugly against the tank, this choice is necessary to adjust the intake air to the furnace.
In order to check the reliability of the welded joint, it is necessary to conduct a thermal test of the stove. Thermal tests are carried out to check the reliability of weld seams under the influence of deformation in the heated state. For this check, it is necessary to install a pair of operating soldering lamps in the direction of the heat chamber and heat the chamber for 30 minutes. If the product does not pull the welding seam when heated and deformed, the oven is ready for use.
Mini-furnace for working out of the gas cylinder
In order to independently produce the furnace with working, the best option is to take the gas cylinder as the main material. Gas cylinders have a suitable wall thickness, which means a long service life of the product.
Made oven with a gas cylinder is able to heat the room up to 100m2.Also, such a furnace is easily remade and under water heating. This oven requires forced air supply. The drawing should be chosen such that it will allow to create a structure, the heating of which will not lead to a fire-dangerous temperature.
In order to make the kiln on the basis of self-working from a gas cylinder, the following tools and materials are needed:
- Roulette and level;
- Welding machine;
- Gas cylinder;
- Iron corners;
- Chimney pipes and burners;
- Fuel tank, but not less than 10 liters.
specialists. Now it is necessary to review the schemes or drawings for making the furnace yourself.
The gas cylinder has a wall thickness of 15 millimeters. If the thickness of the walls of the gas cylinder is greater, this will not provide the necessary heating of the oil for evaporation. In the chamber, the temperature will be approximately 600 degrees, and for heating the fuel, 300 is needed.
For the production of high-quality construction, care must be taken to remove residual gas. To do this, it is specifically added flavor to determine leakage. The remaining condensate in the gas cylinder must be drained. In some cases, in order to drain the condensate, it is necessary to fill the cylinder with running water, and then drain it. After draining the condensate, the gas cylinder must be buried in the ground and then cut off the top.
The bottom part is not cut, since it will serve as a camera, and the cut top will be used as a cover. Next, weld the iron corners to the bottom of the cylinder, they will become the legs of the furnace.
After marking below at 10 cm, cut through the hole that will be needed for the exhaust pipe. And since the hole that is cut is intended for drawing, the diameter of the pipe must be taken into account.
Insert the pipe in the vertical position into the hole and weld it. That the pipe stood vertically it is necessary to check and adjust the pipe level.
From the place where the pipe is installed in the cylinder, it is necessary to retreat 10 cm to the top of the pipe, to make a hole. In order to make a hole, you can use a welding machine, such holes should be about 10 with a distance of 5mm between each other.
Also in this same pipe we make a hole with a diameter of 80 mm. This diameter is necessary for welding a pipe up to 4 meters in length, it is installed in a horizontal position. A hole is made on the top of the cylinder for pouring the work, the hole for pouring should be 8 cm in diameter.
. Note that even in a homemade furnace that works on working, it is absolutely impossible to fill in oil that has not been cleaned. Otherwise, pouring unrefined oil can lead to fire and explosion.
To ensure the heating of water, food must be made a tray. To make a tray, you can use a channel, which must be welded to the lid.
What are the features of the
drip furnace? The ashtray oven is ideal for not large rooms. And the construction of such an assembly with their own hands is very affordable, and most importantly budgetary. A homemade miniature blast-type oven with supercharged is an excellent heater not only in the garage, but also in the house. It is not only safe, but it is also easily constructed if you have a ready-made scheme. And to get a fire, you can use engine oil. In the flow can be taken any recycled oil consistency.
The collected dropper has several advantages:
- Fuel economy;
- Such an oven can be made of any dimensions that will be suitable for your premises;
- With ease you can transfer;
- Easy to use;
- Can be used for cooking, but for this purpose, when making the stove, the pipe must be placed on its side.
In the process of combustion, an unpleasant smell may appear and therefore good ventilation of the room is necessary.
When performing work on the manufacture of the dropper by yourself, it is necessary to observe the fire safety technique:
- The furnace should be installed in a room where there is no draft;
- Items that light up easily should not be present, since such a stove needs space;
- Do not use water to extinguish or cool the stove.
Required materials for the manufacture of the furnace: metal sheet;Copper pipe;Branch pipe;rubber hose;Gas cylinder;Cranes;Medical burner. Tools that are necessary for manufacturing: drill, welding machine, clamp.

Making or buying a furnace that works on the workings is possible only if you have the opportunity to purchase or exchange fuel for it inexpensively. Of course, given the current market conditions, it's possible to find up to 200 liters of fuel, but if you often use an oven, you will need more fuel, especially if your heat source is powerful. Therefore, if you are going to do or buy a similar oven, pay attention to its technical features.
