Oil stoves are the most suitable option for heating garages, warehouses and work areas. The result of the operation of such equipment combines the low cost of the fuel used and good heating. Waste oil (it is also called mining) is classified as a type of waste that is available at any service stations in large quantities. Oil can also be found in garage farms. It is difficult to recycle and almost impossible to dispose of.
As for waste oil stoves, they are for the recycling of this product. Whatever oil that has served its time, motor, transmission or industrial, it can be used as a fuel. Home-made heating installations are capable of operating on it.
Features of operation
Oil ovens have a special design, due to which it is quite possible to manufacture appliances on your own. Among the advantages of this typeheating can be distinguished by mobility, efficiency. Similar designs can even be used as cooking surfaces (this applies to their upper part).
Ovens operating on waste oil are economical not only in maintenance, but also in manufacturing. This includes the consumption and choice of fuel. Owners of small garages and warehouses prefer just such devices for the reason that they are small in size. That is why the furnace body can be easily dismantled and moved to another location.
Oil stoves are non-volatile. The use of such equipment is not associated with either gas pipelines or electricity networks. The device does not require the use of additional power sources, such as batteries or accumulators. However, you should be prepared for the fact that there are some difficulties associated with the use of waste oil heating furnaces. These include the need to install a fairly high chimney, its size should be equal to 4 meters. Among the minuses is the weekly systematic cleaning of the structure from soot and dirt.
Preparation of materials
Oil ovens are quite easy to make, and there is no need to purchase any products. You can use scrap metal, which can be found in any garage. The prototype for the manufacture of the furnace will be the compressor housing from an old refrigerator or a cylinder. You will need thin-walled pipes that have a length of 4 meters. As for the diameter, it can vary from 8 to10 centimeters. These elements will serve as an additional and main radiators. Another pipe will be needed for the hood.
Method of manufacturing a single chamber oven
Cast iron furnaces for mining can be purchased at the store, but if you decide to make a metal version of this design, then you should consider that during operation it must be in an upright position. To do this, you will need to prepare the legs, corners or pipe sections are perfect. Having prepared pieces of metal, each of which will be 20 centimeters long, you need to weld them to the body of the future structure. Then a homemade heater is installed.
In the upper part of the device you need to cut a hole for the hood. Its dimensions must correspond to the radius of the prepared pipe. You can try to drill a small hole with an angle grinder, as for a large diameter hole, it is best to do such work with a welding machine.
Production of a pipe for exhaust hood
According to users, cast iron stoves are not very durable, as they tend to burn through. It would be much more practical to make such an installation yourself.
The next step is to weld the exhaust pipe. Holes should be made in it; to perform these manipulations, it is recommended to use an angle grinder with a cutting wheel. It is necessary to arrange the holes at a distance of ten centimetersfrom the body. Their height should be 0.5 meters or less.
After one meter, in the same pipe you need to make an incision of 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 structure, you need to make a hole for the fuel supply. Such an iron stove is the simplest option, which you can then improve. To do this, a sheet of iron should be placed on a horizontal radiator, then the stove can be used not only for heating, but also for cooking, as well as for heating water.
Production of a double chamber oven
An iron oven can have two chambers. They will be interconnected by a piece of pipe of impressive diameter with holes drilled in it. The lower half of the structure will be a tank for used oil, which will be used as fuel. At the same time, it will act as a combustion chamber and an evaporator.
Working on the bottom part
If you decide to make a similar furnace for testing, then keep in mind that it should be equipped 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. A hole should be made in the lower case, which is covered with a damper. This is needed to adjust the modesoperation and supply of oil to the chamber.
Case making
If you decide to make an efficient furnace for mining, then a pipe will need to be welded into the top cover from the bottom of the located body, which is pre-supplied with holes. This will become an afterburning chamber, in which vapors of boiling fuel will burn out. If you make a design according to this scheme, then you can ensure almost complete combustion of the oil. A cylindrical heated body is welded to the upper part of this heater. There should be a partition inside, which will be needed to trap warm combustion products.
Chimney making
The furnace device 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 allowable limit is from 3 to 4 meters. The chimney can be placed not only vertically, but also, if necessary, at some angle. The garage oil oven will only work continuously if the fuel supply in the housing can be ensured. To do this, you can strengthen the additional capacity, which is located above the evaporator. The container must be connected to the last component by a separate metal pipe.
Increase in efficiency
If the garage oil oven is not working efficiently enough, you can try to increase the efficiency. For this, expertsit is advised to direct the air flow forcibly to the upper part of the structure, for which it will be necessary to slightly change the circuit. An air heating chamber is installed on the upper compartment of the devices. In the immediate vicinity of it, but at a safe distance, a fan should be fixed. With the help of it, air will be pumped into the exchanger, heated and supplied to the heated room. If an oil oven is made with your own hands, then it can be improved by adding a water circuit. This will allow you to heat several rooms at once in one building.
Waste oil design device
If you will be doing an oil oven with your own hands, then it is important to first familiarize yourself with its device. It is possible to distinguish between these designs by the method of supplying oil and the absence / presence of pressurization. If the latter is used, it will be possible to increase the combustion temperature, and, consequently, the efficiency. However, in this case, you will certainly encounter rapid wear of the case, which will lead to the need for repairs.
The device of the furnace is quite simple, which is why you can 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 shutter and a hole. The damper is located in the lower tank, which is called the firebox. There should be a partition in the upper container. This compartment is called the afterburner. Experts do not advise to supplement the designcontrol nozzles, droppers and other parts that can make it difficult to operate the oven. Adjustment should be carried out without automation, you will have to move the damper manually. The last element should be placed above the hole into which the used oil is poured. If you wish, you can heat the oven only a little or heat it up to 900 degrees.
Making a mining furnace from a gas cylinder
Before you make an oil oven, you should consider that the process technology may be different. For example, to organize the operation of the unit, you can use a conventional gas cylinder. The technique was described above, where sheet metal is used. For professionals, it is not difficult to cut the material, and then weld it, forming two combustion chambers. In the absence of experience, seek help from specialists.
At the last stage, you will need to strengthen the legs, and then connect everything with a pipe. However, these operations involve rather long work with the welding machine. In order to reduce the technology, folk craftsmen use traditional gas cylinders. Such metal furnaces are quite durable, since the containers have thick walls. This makes it possible to ensure fire safety and a long service life.
Regardless of whether sheet metal or a balloon is used for manufacturing, when creating a structure, certain rules must be followed. The air supply to the first chamber must necessarily be regulated. For this, the usuala damper that can be opened slightly when there is a gap of arbitrary size. The compartment into which the combustion oil is fed should always be dismantled, this will allow for easy cleaning. Before carrying out work, you must carefully study the instructions. Furnaces of this type should be provided with good traction. To do this, the length of the chimney must be made exactly as recommended above.
Production method
Before using the balloon, it must be carefully prepared. To do this, all the gas is released, and the inner surface must be washed. The bottle is filled with water. In no case should you start cutting the product if you have not completed all the steps to eliminate the gas.
The upper and lower parts are cut off from the balloon. The resulting halves will be used to make a collapsible combustion chamber for testing. Metal legs should be welded to the bottom. In the upper part of the first chamber, you need to make a hole into which a piece of pipe is installed. The last element should be provided with an adjusting plate. Air and oil will flow through the holes.
If you are making an oil oven, the drawings of this design should be studied before starting work. In the center you need to make the same hole to which the pipe is welded. It will connect both combustion chambers. It has several holes for air flow. 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 fin althe stage should be to make and install a chimney.
To ensure that the oven does not lose stability on an uneven surface, legs freely adjustable in height must be welded on the bottom.
Operational safety
Installation of the stove must be carried out on a surface that will ensure fire safety. It can be a metal sheet or any other similar material. It is important to ensure that oil does not splash 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. The draft will be sufficient if you clean the oil tank and chimney weekly. In order to eliminate soot in the upper part of the structure, it is necessary to tap the surface.
Installation of the furnace should be carried out in a place where the structure will not interfere with the movement of people. It is important to exclude the possibility of flammable objects nearby. In front of the firebox, it is necessary to place a material that does not ignite and does not burn even with direct exposure to fire.
Conclusion
As for auto repair enterprises, they do not experience a lack of working out, however, if you are an ordinary car enthusiast, it is recommended to acquire a container of a suitable volume. It will be possible to collect oil, which can be obtained in the summer. In winter, this fuel will be used efficiently.
If you do not have a car, but decide to make or purchase a similar oven, thenit is necessary to inquire about the presence of unnecessary mining at service stations. Employees of enterprises of a similar orientation are almost always ready to share a resource for free or at a low cost. This is very beneficial, since you do not have to spend money on fuel at all. That is why the described designs are so popular today.
