Oven for self-service

The kiln can be manufactured by different methods. It is excellent is suitable for heating of technical rooms, such as workshops or garage. With the successful selection of the model and the correct of its assembly, this heater not only becomes a good heater, but also helps warm the water for tea preparation, hand washing or other technical needs.

In these workrooms, not always has an place for storing firewood or other fuel, but spent fuel from , such as transmission and engine oil, is usually found in excess.

Waste oils are most often sent for recycling, so they can always be obtained almost in vain, saving on electricity or buying firewood. The heat transfer from the burned off work can be called equal heat from the electric heater, and the fuel consumption is from half to two liters per hour.

This heating method has many advantages, but there are some disadvantages. The information on them will help to understand what should be paid special attention in the process of manufacturing and operating the furnace.

Advantages and disadvantages of furnaces for working

Oven heater The following points can be attributed to the advantages of the waste oil furnace:

• Such furnaces heat the enclosed spaces well, therefore they are suitable not only for technical premises, but also for heating small greenhouses and agricultural buildings where pets are keptand a bird.
• A properly designed oven does not smoke and does not give a lot of burning.
• Such a heater is very simple to operate ;
• Since the test itself does not burn, and only burns its pairs, the furnace can be called fire-safe enough, if the rules of its operation are observed.

The drawbacks of this heating method include:

• In the furnace, it is not possible to use castings having impurities - this is explosive. At best , waste from burning such fuel will quickly clog the filter and nozzles, so it must be filtered before use, but you can also buy filtered oil.
• Chimney, as well as the furnace itself, quite often require cleaning from combustion products ;
• In the process of its intensive burning, the furnace is very loud.

Types of furnaces operating

The waste oil kilns can be manufactured on their own, and it is possible to adapt the pyrolysis unit or the furnace with the turbo burners to this fuel, since they work in the same way as the combustion of dedicated fumes.

. In this case, in the vacuum chamber of the furnace, if there is a lack of oxygen, the workout is heated, and occurs with its decomposition. In the process of decay, evaporation is evolved, which rises to another chamber where oxygen is already intensively supplied. There evaporation is burned, giving off a lot of heat.

Convenience of using this type of furnaces is that the burning intensity can be changed by increasing or decreasing the oxygen supply to the pyrolysis camera.

The disadvantage of using in similar pyrolysis aggregates is rapid contamination of chambers and chimney by combustion products. In addition, at this type of heating it is impossible to maintain the temperature automatically, therefore it is necessary to keep the furnace under constant control.

Self-similar devices that work on spent raw material from gas or oxygen cylinders of large or small size, pipes of various diameters or metal sheets are manufactured on their own. The design of the unit on the working can be with a drip fuel system or with blower .

Exhaust Furnace Made from Gas

cylinders from oxygen or natural gas are excellent for making the as the waste. They have the desired form, and the thickness of the metal will allow the instrument to be used for a very long time.

The stove, made of a standard-sized balloon, will heat the room in 70 ÷ 85 sq. M.m., and in addition, by slightly refining the design, it will be possible to use such a device for the water heating circuit. Such furnace does not require the turbo burner for forced oxygen supply. The test is received by the by the in .

In order for to make such an oven, it is necessary to have the following materials:

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

tools from require a welding machine, a drill, angle grinder , a "Bulgarian" machine, a tape measure, a building level, another standard metalwork tool.

gas-fired heater

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

• The accumulated condensate is drained from the cylinder, and the is thoroughly rinsed with water in several receptacles of the .The whole process must be carried out on the street.
• Next the is installed vertically and poured to the very top with water. For stability, the balloon is buried in the ground halfway or installed in a narrow tray, which has a large weight.
• Then marks are placed for a smooth cut of the top of the cylinder.
• The upper part of the of the container is cut by a bulgarian, and, of course, water begins to flow from it. It is necessary to wait until it flows to the level of the cut, and then cut off the top completely.

The trimmed part will then become the fuel cap, and the bottom of the cylinder will warm the room. Now the water from the cylinder can be drained completely.

• The balloon is better to lift from the floor, therefore it is necessary to weld the legs from the steel corner to the bottom part of the cylinder, they should be about 200 ÷ 250 mm high.
• Then the trimmed cylinder is installed on the legs, and at a distance of 70 ÷ 100 mm from the top, a round hole for the chimney is cut by welding. The hole must have the same diameter as the prepared nozzle about 400 mm long.

This nozzle is installed and welded into a cut hole. The welding seam should be even and tight.

• Then, a vertical section of 3.5 - height is welded to the horizontal pipe with a vertical transition with the help of a tap. The chimney pipe is then taken to the street.
• At the bottom of the cylinder, a square hole is cut out, which will serve as an ashtray. It is fitted with a door that will help regulate the amount of air supplied.
• The next step is to make capacity for fuel, which will install on the bottom of the cylinder. It is usually made of a piece of pipe, 70-100 mm in height and 140 mm in diameter. This tube is sealed from below.
• The lid for the is cut from the metal sheet, and in this two holes are cut from the top:

- 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, on it is fastened to the movable cover. Through this hole in the capacity fuel will be added and the air supply will be regulated.

• Then, in a pipe height equal to the height of the balloon and a diameter of 100 - 110 mm, one end is brewed with a round metal blank, equal in diameter to the cylinder size. The lower end of the pipe is welded into the tank for fuel. A design resembling a bar is obtained.

• Drill five rows of seven holes with a size of 10 mm. They should be distributed at 400 mm of the height of the lower part of the pipe of the resulting "rod".
• Further the received design is installed inward of the prepared balloon. At the top, the lid is welded to its walls.
• Now it is possible to fill the lower tank with fuel and carry out the test - , this process is better carried out on the street. If he passes successfully, you can put the stove in the room and take the chimney out.

In the first scheme, the elements of the furnace are worked out slightly differently, and the mounting of its is more complicated, but the effect of using the unit will be the same.

Another is one version of a kiln for working which can heat a room, heat water, and when the circuit is connected to water heating, the is good for use in greenhouses and incubators.

The work is carried out in the same sequence as in the production of the first model, but with some deviations, since in this case, it is necessary to make a sealed tank for water. Its is located at the top of the cylinder, and through the it will pass the heated pipe, according to the principle of the samovar, giving heat to the water that will flow into the heating system or to the points of the .

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

Spindle furnace, made of sheet metal

More common and a popular model of the unit on the working is a design made of metal sheets. This is a logical explanation: firstly, it is compact, and secondly, the weight its is only 25 - 30 kg,and thirdly, the advantage is the presence of a kind of cooking plate, which will help not only to warm the water, but also will allow to prepare simple food.

sheet metal kiln. It should be noted that there are several types of furnaces that differ in appearance, but they work in accordance with the same principle.

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

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

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

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

- metal corner 30 × 30, with 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 compile drawing furnace designs. You can develop it yourself, or you can use the ready-made option, making your additions, if necessary,
