Overall operation principle
If we want to get high-quality heating system based on mining, oil can not simply be set on fire, because it is smoke and stink. In order not to suffer from the unpleasant and hazardous side effects, it is necessary to heat the fuel so that it began to evaporate.
Burns are obtained by heating the volatiles. This is the basic principle of operation of the heating unit at working out.
Use of a perforated tube
To implement this principle in stove construction provide two chambers which are interconnected tube with holes. In the lower chamber through the filler opening is supplied fuel, which are the same, and heated. Formed in this volatiles rise up through the tube, through the perforations being enriched with air oxygen.
The resulting combustible mixture is ignited already in the tube, and its complete combustion occurs in the upper chamber of afterburning, which is separated from the flue special partition. If the process technology adequately observed, soot and smoke during combustion is practically not formed. But the heat will be sufficient to heat the room.
Using plasma bowl
In order to achieve maximum efficiency of the process, you can go to a more complex way. Recall that our objective is to separate the fuel from volatile constituents by heating. For this purpose, a single camera unit should be placed cup of metal, you want to not only heat and to heat.
Through a special spout of the fuel tank into the chamber a thin stream or testing of droplets will arrive. Getting on the surface of the bowl, the liquid instantly evaporate, and the resultant gas would burn.
If everything is done correctly, the combustion gases must be accompanied by a bluish-white flame. Related flame can be seen at the plasma combustion burning bowl so often called plasma. But the technology itself is called drip feed: for fuel when it has to do exclusively with small doses.
For all the variety of structures, operation of all heating units in the bargain fuel based on the principle described above.
Advantages and disadvantages
It would seem that the idea is practically devoid of deficiencies, but it is not. To make an informed decision about using in your home such heating, it is necessary to see not only the advantages of its use, but also disadvantages.
Let's start with the advantages of the method. So, if you have regular access to junk fuel, what in fact is to work, then you can effectively use and at the same time to dispose of this material. Proper application of the technology allows to receive heat from the complete combustion of the material without release into the atmosphere of harmful substances.
For other advantages include:
- uncomplicated design of the heater;
- low fuel costs and equipment;
- the possibility of using any oil which is in the economy: vegetable, organic, synthetic;
- combustible material can be used, even if the contamination is a tenth part of its volume;
- high efficiency.
Disadvantages of the method should be taken very seriously. Failure to observe the process technology, can occur incomplete combustion. Its vapors are dangerous to others.
No wonder the main requirement in the regeneration heating to working out is the presence of air in the room where the boiler will be operated.
We list and other disadvantages:
- as for good traction need high-quality chimney, it must be right, and its length - five meters;
- chimney and plasma cup must be regularly and thoroughly cleaned;
- complexity dropping technology is problematic ignition: bowl should already be at the time of glow fuel supply;
- boiler operation causes air drying and burn-out of oxygen;
- independent creation and application of hot-water structures can contribute to lowering the temperature in the combustion zone, which jeopardize the effectiveness of the overall process.
To solve the last of the problems mentioned above, it is possible to mount a water jacket, where it can not affect the quality of combustion - on the chimney.
These disadvantages have led to the fact that the product without significant modifications almost never used for home heating.
Where to apply and how to modify
In view of the substantial list of shortcomings in the waste oil heaters are rarely used in homes. But they are widely used for heating engineering and production areas. Motorists it is their use in garages, gardeners - in greenhouses, livestock breeders - in outbuildings. At car washes at service stations, in warehouses, where there are no combustible materials, it is always a place.
Often the basic design are subject to all sorts of refinements. For example, for this purpose use a water jacket or hot water coils. Such equipment include heating of the water. Furnaces of this type have to work with automation, otherwise they will have to vigilantly monitor the operation.
Some good homemade
Using the basic design principle, it is always possible to come up with a product that will best meet your own needs. We will try to offer you some options, not only worthy of attention, but also the implementation.
Option # 1 - with ready body
This design may like this home handyman, who has mastered the skills of welding. Its essence lies in the use as a basis the finished product casing - an oxygen or a gas cylinder, or barrel tubes with thick walls.
To visualize the process of converting blanks into the oven on working out, consider the chart below carefully.
The paper products used plasma thicket and therefore drip feed technology. It is able to produce approximately 15 watts of heat, which will warm up to 150 m2. It is not necessary to try to upgrade this model, with the aim to increase its productivity by increasing the air flow or changing the dimensions of the combustion chamber. This can lead to an increase in volume of the soot and fumes that is unsafe.
First we need to build a base model - its body. To do this we need a tube of 780 mm in height, 210 mm in diameter and with a thick (10 mm). The bottom of the housing is cut out from the steel sheet (5 mm). Bottom circle diameter is 219 mm. It only remains to be welded to the bottom of one side of the housing.
Feet that you have to be welded to the bottom, can be made of solid bolts. To monitor the combustion process inside the pipe and to be able to start the heating of the bowl, it is necessary in 70 mm from the bottom to make a viewing window casing. For this purpose, the housing should be cut a hole of a size that it is functional - comfortable for the user.
The cut portion of the tube goes to manufacture door opening. We just need to be welded to it a neat collar and lay it on the perimeter of the asbestos cord to the door tightly closed hole. Fasten the door to the housing by means of bolts.
For chimney pipe diameter will need a 108 mm thick wall (4 mm). It should be welded to the body on the side opposite the one where the cut through the viewing window. Turn away from the top 7-10 cm.
To make the cover sheet metal (thickness 5 mm) was cut round billet of 228 mm diameter. Along the edge of the workpiece to be welded bead. This requires a metal strip 3 mm in thickness, and width - 40 mm. In the resulting lid side make another observation hole diameter of 18 mm. His door will act as a safety valve.
In the center of the lid cut another hole with a diameter of 89 mm. It is inserted into the air supply pipe, which makes the blank length 76 cm, diameter 89 mm and wall thickness of 3 mm.
Workpiece punching. For this retreat from the edge 5 cm and 9 are drilled around holes of 5 mm diameter. After 5 cm is necessary to do two more rows of holes - 8 in number, diameter 4.2 mm. After another 5 cm do fourth row of holes - 9 pieces, 3 mm in diameter.
To perform the following work, we need a Bulgarian. Along the edge of the tube, from which we retreated 5 cm, cut gap height of 3 cm, 1.6 mm thick. The circumference of such slits should be 9 units.
From the opposite end of the tube is 5-7 mm from the edge of slotted hole 10 mm in diameter. It will be inserted into the fuel supply pipe 10 mm in diameter and 1 mm in wall thickness. As can be seen from the diagram, it enters the pipe for the air and terminates simultaneously with it. The length of the fuel pipe and its bending angle depends on the location of the oil tank.
Pipe for supplying fuel and air in the welded assembly to the lid. When installed in the enclosure product it should not rest on the bottom, and it does not reach to 12 cm.
Getting to the manufacture of plasma bowl. This will require a thick-walled tube (4 mm thick) of diameter 133 mm. Cut off from it a piece of 3 cm. From the steel sheet 2 mm thick cut out a circular blank with a diameter of 219 mm. The billet is welded to the segment and get the cup.
Actually, the stove is almost ready. Still needed it. To do this, inside the body of 7 cm from the bottom of the cup place. Now, it should be clearly visible from the viewing window located at the bottom. Of the cup and set fire to the window. We put on provided to cover it with means for supplying air and oil.
Chimney, which will be attached to the respective pipe, the pipe is made of 4 mm and a diameter of 114 mm. The length of the flue should not be less than 4 meters. The peculiarity of it can be considered exclusively vertical arrangement. No inclined sections should not be! The outer part of the chimney should be warm.
When the oil tank is installed, you can check the operation of the unit. To do this in a bowl placed paper moistened with fuel, and then set fire to it. In the final step the paper can start burning fed detention.
The circuit of this device is nothing like as shown. We want you to get a quality machine that will long to please its creator smooth and safe operation.
Option # 2 - most popular
This model is really popular with the owners of summer cottages and garages. Make it easy. It is composed of two compartments (chambers). The bottom is filled fuel which is heated to form volatile gases. When passing them through a perforated pipe located between the compartments, is saturated with oxygen gas and inflammation.
During the combustion of the gas mixture in the upper compartment temperature may reach 800 degrees. Such heating requires an active air supply. For this purpose, a viewing aperture through which, in addition, fuel is poured into the lower compartment. To use it to adjust the air supply valve is needed.
When passing gas from the lower part of the structure in the upper oxygen saturation of the mixture goes through the small holes (diameter 10 mm) in a pipe.
To perform work should be prepared:
- grinders with cut-off and Grinding Discs; The minimum disc diameter - 125 mm.
- Hammer drill with not less than 13 mm;
- the welding machine (200 amperes) and a protective mask or goggles;
- hammer, chisel and pliers;
- corner legs;
- steel sheet;
Sheet metal cut out and boiled lower compartment. It excised viewing window through which will flow into the fuel and air. Valve for this hole is fixed to cover the rivet body.
To the lower chamber welded perforated tube-connecting pipeline to which is attached by welding the upper compartment with a removable lid. It also cut out of sheet steel and welded. During the welding process should be carefully checked for possible gaps.
metal corners used to impart better stability design. The flue should be attached to the pipe vertically.
Check operation of the boiler can be, bay oil in the lower compartment. There he set fire, using for this purpose plain paper.
The process works similar, but slightly modified stoves can be viewed on a video in the final part of this article.
Option # 3 - small but udalenky
For large areas need productive stove from previous versions. But there are also baby-units, which also have much to. Here is a homemade product weighs only 10 kg. At a flow rate of 0.5 liters of fuel per hour it is capable of delivering up to 6 kW of heat. It can raskochegarit and stronger, but to do this it is not necessary for safety reasons: to explode. A great option for heating the garage.
If you have an old gas tank, then it is he can become a fuel tank for this homemade. Capacity for oil collected from the top and bottom of the cylinder. It is recommended to keep the circular seal with the sealing ring which further increase the strength of the product.
If the gas bottle is not present, then the suit and any other container of 350 mm and a diameter of 200 to 400 mm. From it and be welded to fuel tank combustion.
To create an air-fuel mixture using a tube wall which is not less than 4 mm thick. The cone can be cooked from solid steel of 4 mm thickness. The scheme represents all design sizes. They can be adjusted in smaller and in a big way, but no more than 2 cm.
Particular attention should be given to the seams in the transition areas to the cones: this is due to combustion of the mixture of the active maximum heating gases can occur.
A chimney for the stove make this length is not greater than 3.5 meters, so when you create too much of the active fuel rods are not dragged into the pipe. Such stretching can not only increase fuel consumption, but also reduce its heat.
This can be used in home-made hot-water heating embodiment. For this purpose, as shown in the right figure circuit around afterburning zone wound steel tube through which water will pass. In order to prevent a significant reduction in the gas temperature, the coil is closed steel shell reflecting heat. Heated in this way the water goes into the heating system.
Compliance with safety regulations
For safe operation of the self-made heating to working out you need to pay special attention to the quality of the oil. It should not be present substances capable of easily ignited - benzene, acetone and others. Quality automotive wastes, usually leaves much to be desired. Their use may form carbon deposits that have to clean off from time to time.
In addition, observe the safety precautions listed below.
- The diameter of the chimney must not be less than 10 cm. Preferably sandwich chimney: less soot deposited on its surface.
- Near the boiler can not be flammable substances, including the fuel tank. Only at a safe distance.
- Eliminate from entering the chamber with the hot water with oil or another fluid. The consequences of such leakage are shown in the video in the final part of this article.
- In operation, waste oil boiler heating temperature much higher than those achieved by the combustion of solid fuels. Therefore, for this design, and is selected thick-walled materials.
- It is desirable to equip a boiler of forced air circulation system.
Do not leave the machine running unattended. This is effective, but rather a dangerous thing.

Master-craftsmen made no secret of their own developments and are always ready to share achievements, show homemade work. Pay attention to the video, which shows the same furnace as in option # 2, but with some modifications. See how it works, what is the result of its use in the conditions of the external cold to warm relatively spacious garage premises.
Once again I draw your attention to safety precautions that should be observed when using improvised stoves on the mining.
Junk fuel that can get to you, if not entirely free, then for a mere penny, always draws attention rukastogo owners garage workshops, greenhouses or other non-residential premises, requiring heating. Yes, talented people can literally waste to do the necessary thing in the economy. But the ability to does not come from the outside: it is work enough. Perhaps our information will help not only to those who already know how, but also for those who want to learn to do everything with their own hands.
