Oily furnaces with their own hands: blueprints, how to make a device

Oily ovens are the most suitable option for heating garages, storage and work spaces. The result of the operation of such equipment combines the low cost of used fuel and good heating. Waste oil (it is also called mining) is referred to the types of waste that are available at any maintenance stations in large quantities. Oil can be found in the garage. It is difficult to process and almost impossible to utilize.

As for furnaces on waste oil, they act to reuse this product. Any oil that has served its term, motor, transmission or industrial, it can be used as fuel. On it homemade heating installations are capable to work.

Features of operation

Oily furnaces have a special design, due to which it is possible to manufacture the instruments independently. Among the merits of this type of heating can be identified mobility, economy. Similar designs can be used even as cooking surfaces (this applies to their upper part).

Furnaces operating on waste oil are economical not only in maintenance, but also in manufacturing. This can include fuel consumption and choice. Owners of small garages and storage facilities prefer these devices because they have small dimensions. That is why the furnace body can be easily dismantled and moved to another location.

Oily furnaces are non-volatile. The use of such equipment is not connected either with gas pipelines or with electricity networks. The device does not assume the use of additional power sources, for example, batteries or batteries. However, you must be prepared for the fact that there are some difficulties associated with the use of heating ovens operating on waste oil. They include the need to install a fairly high chimney, its size should be equal to 4 meters. Among the minuses - and the weekly systematic cleaning of the structure from soot and dirt.

Preparation of materials

Oily furnaces are made quite simply, and there is no need to purchase any products. You can use scrap metal, which will be found in any garage. The prototype for the manufacture of the furnace will be the compressor casing from the old refrigerator or cylinder. We will need thin-walled pipes that have a length of 4 meters. As for the diameter, it can vary from 8 to 10 centimeters. These elements will act as an additional and basic radiator. Another pipe is needed for drawing.

Method of making a furnace with a single chamber

Cast iron stoves can be purchased at the store, but if you decide to make a metal version of this design, then you should take into account that during operation it should be in an upright position. To do this, you will need to prepare the legs, perfect fit corners or pieces of pipe. Prepare pieces of metal, each of which will be 20 centimeters long, you need to weld them to the body of the future design. Then a homemade heater is installed.

At the top of the device, you need to cut a hole for drawing. Its dimensions should correspond to the radius of the prepared pipe. A small cutout you can try to drill with an angle grinder, as for a large diameter hole, it is best to perform such work with a welding machine.

Making a pipe for drawing

According to users, cast iron ovens are not very durable, as they have the property of burn out. It will be much more practical to make such an installation yourself.

At the next stage, you will need to weld a pipe for drawing. It should be made holes, to perform these manipulations, it is recommended to use an angle grinder with a cutting circle. Place the holes at a distance of ten centimeters from the body. Their height should be 0.5 meters or less.

Having retreated one meter, in the same pipe it is necessary to make a cut in the second pipe, which is useful for an additional radiator. To perform these works, it is best to use a welding machine. The additional radiator must be parallel to the floor.

At the top of the homemade design, you need to make a hole for fuel. Such an iron furnace is the simplest option, which you can improve after. To do this, the horizontal radiator should be put iron cloth, then the oven can be used not only for heating, but also for cooking, as well as for heating water.

Furnace with two chambers

An iron stove can also have two chambers. They will be connected with each other by a piece of an impressive diameter pipe with holes drilled in it. The lower half of the structure will be a waste oil tank, which will be used as a fuel. At the same time, it will act as a combustion chamber and an evaporator.

Working on the bottom

If you decide to make such a furnace on the working-off, then consider that it should be provided with legs. The air gap between the bottom of the structure and the floor will be an additional factor that will improve the heating of the room. In the lower case, make a hole, which is covered by a flap. This is needed to adjust the operation modes and supply oil to the chamber.

Making the case

If you decide to make an efficient furnace on the working, then in the top cover from the bottom of the located housing will need to weld a pipe, which is pre-equipped with holes. It will become a burnt chamber, it will burn out fumes of boiling fuel. If you make a design in this way, you can ensure almost complete combustion of the oil. A cylindrical heated housing is welded to the top of this heater. Inside, there must be a partition, which will be needed to delay the warm combustion products.

Chimney manufacturing

The device of the furnace assumes the presence of not only two chambers, but also a chimney. The pipe must be welded to the top of the module for heating. The diameter of this component should be equal to one hundred millimeters. As for the length, the permissible limit is from 3 to 4 meters. The chimney can be placed not only vertically, but also if necessary at some angle. The oil oven for the garage will work continuously only if it is possible to ensure uninterrupted supply in the fuel housing. To do this, you can strengthen the additional tank, which is located above the evaporator. With the last component, the container must be connected by a separate metal pipe.

Increase in efficiency

If the oil oven for the garage does not work efficiently, then you can try to achieve an increase in efficiency. To do this, experts advise to direct the airflow forcedly into the upper part of the structure, for which it will be necessary to change the circuit somewhat. An air heating chamber is installed on the upper compartment of the instruments. In the immediate vicinity of it, but at a safe distance, a fan must be fixed. With it, the air will be pumped into the exchanger, heated and fed into the heated room. If an oil oven is made by one's own hands, then it can be improved by adding a water circuit. This will allow heating several rooms in one building at once.

Design of the structure on waste oil

If an oil oven is performed by hand, it is important to first familiarize yourself with its device. It is possible to distinguish between these structures by the oil supply method and the absence / presence of a boost. If the latter is used, it will be possible to increase the combustion temperature, and consequently, the efficiency. However, in this case, you will inevitably encounter a rapid wear of the case, which will lead to the need for repair work.

The appliance is quite simple, that's why it's possible to build it yourself. The design assumes the presence of only a few elements, namely two chambers, a connecting pipe, and a chimney.

As for the lower chamber, it must have a flap and a hole. The damper is located in the lower tank, which is called a furnace. In the upper tank there must be a partition. This compartment is called afterburner. Experts do not advise to supplement the design with regulating nozzles, droppers and other parts that can make it difficult to operate the furnace. Adjustment should be carried out without automation, it is necessary to move the flap manually. The last element should be placed above the hole in which the used oil is poured. If there is a desire, then you can heat the oven only a little or to heat up to 900 degrees.

Making a furnace on the gas cylinder

Before you make an oil stove, you must consider that the process technology can be different. For example, to organize the operation of the unit, you can use a conventional gas cylinder. Above, a technique has been described where sheet metal is used. For professionals to cut the material, and then weld it, having formed two combustion chambers, it's easy. If there is no experience, contact a specialist for assistance.

At the last stage it will be necessary to strengthen the legs, and then to connect everything with a pipe. However, these operations assume a fairly long work with the welding machine. In order to reduce the technology, folk masters use traditional gas cylinders. Such furnaces made of metal are quite strong, since the containers have thick walls. This allows to ensure the design of fire safety and long life.

Regardless of whether sheet metal or a balloon is used to create a structure, one must adhere to certain rules. The air supply to the first chamber must be made with the possibility of regulation. For this purpose, an ordinary damper is ideal, which can be opened slightly when there is a gap of arbitrary dimensions. The compart- ment into which the combustion oil is supplied must always be dismounted, this will allow easy cleaning. Before carrying out the work, you should carefully read the instructions. Furnaces of this type should be provided with good traction. To do this, the length of the chimney must be done exactly as recommended above.

Manufacturing procedure

Before using the cylinder, it must be carefully prepared. For this purpose, all gas is produced, and the inner surface must be washed. Water is poured into the cylinder. In no case should you start cutting the product, if you have not made all the actions to eliminate gas.

The upper and lower parts are cut from the cylinder. The resulting halves will be used to make a collapsible combustion chamber for working. Metal legs should be welded to the bottom. At the top of the first chamber you need to make a hole in which a piece of pipe is installed. The last element should be provided with an adjusting plate. A stream of air and oil will flow through the holes.

If you are making an oil stove, the drawings of this design should be studied before work commences. In the center, you need to make the same hole to which the pipe is welded. It will connect both combustion chambers. In it, several holes are made for air flows. The sheet metal and the middle part of the cylinder will be used to make the secondary combustion chamber. It must be welded to the connecting pipe. At the final stage, a chimney must be made and installed.

In order for the stove to remain uneven on the uneven surface, it is necessary to weld the legs in the lower part, freely adjustable in height.

Safety of operation

Installation of the oven must be conducted on a surface that will ensure fire safety. This can be a metal sheet or any other similar material. It is important to ensure that the oil does not spill out of the combustion chamber, for this it is not recommended to fill the tank more than 2/3. If after ignition the oil boils, then it is necessary to reduce the air supply by adjusting the damper. Thrust will be sufficient if weekly you will clean the oil tank and the chimney from contamination. In order to remove the soot at the top of the structure, it is necessary to tap the surface.

Installation of the furnace should be conducted in a place where the construction will not interfere with the movement of people. It is important to exclude the possibility of nearby flammable objects. Before the firebox, it is necessary to place material that does not ignite and does not burn even when exposed to direct fire.

Conclusion

As for car repair enterprises, they do not experience a lack of working, but if you are a regular motorist, it is recommended to acquire a capacity of a suitable volume. It will be possible to collect oil, which will be obtained in the summer. In winter, it will be possible to effectively use this fuel.

If you do not have a car, but decide to manufacture or purchase a similar oven, you should ask about the availability of unnecessary work-out at maintenance stations. Employees of enterprises of this orientation are almost always ready to share the resource for free or at low cost. This is very profitable, since you do not have to spend on fuel at all. That is why the described designs are so popular today.
