Homemade ovens on waste oil. Homemade metal furnaces: turn-by-turn instructions

Every motorist has waste oil, which is often recycled or simply poured on the ground. However, the same garage in winter can perfectly heat a stove on waste oil. Drawings and schemes, which will be presented here, clearly show the principle of action and the materials necessary for its creation. Such a useful device can heat any room, and also works on waste.

The operating principle of the furnace on waste oil

Like any liquid fuel, working off during its combustion produces vapors that are a source of increased thermal energy. The oil itself can not give such a temperature at burning, it only creates conditions for evaporation.

Therefore, homemade ovens on waste oil are divided into two compartments - the lower and upper ones. In the lower burns liquid oil. In the upper, pairs are accumulated and burned, which rose from the first compartment. Due to this, the temperature rises, providing a warm room.

Precisely because of this peculiarity of burning liquid fuel, the furnace on the waste oil is collected from two elements, which are then connected. With regard to air saturation, the lower part is supplied to them only in order to maintain the burning of the oil. But in the upper part make the feed as much as possible to create the maximum temperature in it. This principle ensures the full operation of the furnace, which is capable of heating a room of any size.

Such self-made furnaces for a garage or country houses are divided into three groups:

• In the first case there are two types of heat supply. The room can be heated by water that diverges through the system, or simply the heat from the stove will spread around the room. With water heating, the upper part of the furnace is equipped with a capacity of water, which heats up and diverges through the pipes of the heating system. With the usual heating of the room, the oven can be mobile, because no connections to the systems are required, you just need to pull out the chimney.

• In the second case, homemade metal furnaces are equipped with a drip feed, which ensures a gradual burning of the work, which reduces fuel consumption. However, the mechanism of such a dosed receipt of oil is very difficult to produce at home. They are made in factories using special technology.
• In the third case, the furnace can be naturally pressurized, this is the simplest option, in which there are no additional elements. But it is possible to equip the structure with forced air supply, so it will work more efficiently. In general, it all depends on the skill, the availability of the necessary materials and the area where such a homemade oven will be used.

The design of the oven, which is easiest to make at home

The optimal design that any home master can make in the yard or in his garage is a furnace from a gas cylinder or pipes of the required diameter. That is, the simplest version of the unit without forced air supply and drip oil. However, despite the simplicity of the design, if done correctly, such an oven will heat the necessary room for many years.

Such a design is the simplest, therefore, for its example, we will consider how to make a furnace on waste oil by hand.

Of course, a similar unit can be made from steel sheets, this will require a lot of labor and tools for bending metal, for example, into a pipe. Therefore it is better to make from secondary raw materials - cylinders or finished pipes.

Procedure for producing a furnace from a gas cylinder

The first thing to do is to twist the valve from the cylinder so that all of the gas leaves it, which could remain inside. Then for safety of the further work it is necessary to pour water into it. After that, with the help of the Bulgarian, the top of the balloon, shaped like a hemisphere, is cut off. Then, the bottom of the cylinder is also cut off. A homemade ovens oven is made in the same order as described above. This sequence ensures safe operation with the cylinder, without fear that the gas remains detonate when it is cut.

Creating the bottom camera

The next stage of work is the creation of the lower chamber of the furnace, where the oil will burn. It is made from the cut off upper and lower parts of the cylinder. They are simply connected together so that when the furnace is ready, the chamber can be disassembled to clean it from carbon deposits and fuel residues. For this reason, the connection should not be deaf. It is made on thread or bolts. When everything is ready, the design gets a stand, because the section of the cylinder with the support, which was below, remains there and will further ensure the durability of the finished product.

The upper hemisphere also fits perfectly, it already has an opening in which, when the oil burns, its vapors will rise to get into the upper chamber. They will pass through a perforated pipe, which is welded from above. Its diameter is 10 cm, its length is 36 cm, and 48 holes are drilled in it, 9 mm each. They are designed to supply air in pairs of oil. This mixing provides intense combustion, in which a huge temperature is released to heat the room. Help to study the furnace on the waste oil drawings, which visually display all the nuances of its design. As practice shows, for a perforated pipe to provide sufficient airflow, 48 holes are necessary.

Creating the Top Camera

When all the components of the lower part are assembled, an upper compartment is made in which the vapors and air will burn, providing heat. It is created from the remaining middle part of the balloon, the top and bottom of which will need to be welded with sheet metal circles. After they are cut, a hole is made in the lower circle for connection with a perforated pipe, and in the upper one - for the withdrawal of combustion products. The holes in the side of the circles are cut, but when welding the upper chamber, they must be positioned so that they are from different sides. This will allow to stay with the hot steam, which will heat the space longer. And only after they give their heat energy, they will go through the chimney into the atmosphere.

Additional furnace elements

For more effective consumption of mining, such homemade metal furnaces are equipped with a supply valve, through which the air supply can be regulated. It acts as an ash-pit in a conventional oven. Having adjusted it, it is possible to make the expense of working off more effective.

In addition, the lower part can be completed with a fitting that will feed the oil gradually.

Tips that will help when creating a stove

To make homemade ovens on waste oil work well and be easy to maintain, it is worth sticking to some recommendations when creating them.

The hemispheres of the lower combustion chamber must not be tightly welded. After all, it will be necessary to clean the furnace of carbon. Therefore, this compartment must be dismantled for the convenience of servicing the unit. All other parts must be welded securely. The connection between the spheres can be made threaded or bolted.

Chimney must be strictly vertical and be at least 4 meters - after all, such self-heating stoves must have a good draft. Otherwise, their efficiency is greatly reduced.

The perforated socket must be located only vertically. Otherwise, there is a high probability that all the pairs that must be heated immediately go into the atmosphere without giving proper heat. In addition, the oven will start to smoke.

Tips for operating the oven

Using self-made stoves from metal, it is worth remembering the safety rules that allow convenient and without any risks for yourself to use such a device.

It is necessary to periodically clean the carbon from the chimney, do not wait until the stove starts to smoke or lose its previous efficiency.

Filling the lower compartment with oil should not be more than one third. After all, if it is half full, when boiled, oil can spill out through the perforated nipple.

When the oil boils, it is necessary to track this moment and adjust the valves. This will make the furnace work stable, which, in turn, improves its performance in terms of reducing fuel consumption and at the same time raising the temperature.

Here the principle of creation and scheme of the furnace on waste oil is described in detail, as well as what materials it is better and more convenient to make.

Creating a drip fuel supply

Now with regard to the drip feed of fuel, which, as mentioned above, is very difficult to do. However, you can still choose the parts that are suitable for this.

First of all, you need a filter that will clean the workout before it gets into the drip mechanism. After all, he is very sensitive to the slightest contamination. The selection of details is pretty painstaking, but if you make this improvement, the self-made oven will become much more economical in terms of fuel consumption.

So, you need to install a car filter on the edge of the hose that receives the oil. It must provide absolute filtration, so that the workout is clean and can not clog the drip mechanism. There are filters that only partially make the oil cleaner, they will not work. The filter has a metric thread, so finding a branch pipe on which you can put it on is quite a difficult task. However, you can take a suitable fitting, put a piece of hose on it and insert it into the required hole on the filter. But it should be noted that such cleaning, installed on homemade stoves from pipes or a balloon, must be cleaned regularly, because with the slightest clogging the drip feed will stop working. Therefore, the filter should be constantly checked, but changed once a month.

Pump for oil injection

Now for the pump, which will pump the oil. Excellent fit GAZ 3102-40I from the "Volga". When there is oil inside it, it works hard, but it's good that there is a complete absence of excess pressure at the outlet. At the output of the injector is more than 3 atmospheres. This pump shows itself worthily, only there is one "but" - it is very productive. This is intrepid, because it is easily removable. The diagram clearly shows the solution. Everything is assembled from tees, which are two here, then there are three unions, a nipple, and also a part of a hairpin - it acts as an adjusting rod. After such completion, this device, equipped in a homemade ovens on waste oil, will work perfectly. Because the pump is able to take as much work out as will allow the interior space of the case with the core in it. And all that is left, comes back.

At the bottom, a part of the dropper is put on, and the fuel supply will be regulated by it. From there, the oil enters the funnel. The feed rate is adjusted so as to maintain a stable combustion, and no more. If the test will be typed up a little faster, the homemade ovens will start to smoke, which is undesirable for obvious reasons.

Nuances of adjusting the droplet feed

However, if you make too little oil in the furnace, the flame will go out. In general, it is worthwhile to find a center that will provide the most productive combustion for the operation of the furnace. When changing fuel, the settings also change, because they are heavily influenced by viscosity and temperature, which should be from 10 to 20 degrees. Also affect the properties of the oil itself, which is poured into the lower chamber. After all, the stove can work on all fuel and lubricants, and the drip mechanism is very fastidious to the fact that it is poured. For these reasons, it is always necessary to regulate this equipment for a specific oil, which falls into homemade furnaces for a garage or villa.

Safety rules for handling the furnace during working

Such a furnace design can work on any liquid fuel. However, avoid flammable liquids, such as acetone or gasoline. It is best to use oil, it does not flare up so quickly, therefore it is more predictable, and therefore safer.

You should take a special place for the oven, where there are no drafts. After all, a random flow of air can dramatically increase the flame, and such changes are very dangerous from the point of view of safety.

Using such home-made heating ovens, you must carefully monitor that there are no combustible objects near it. It is for this reason that the space around the unit is better kept empty, this will keep everything under control.

Now with regard to the integrity and integrity of the product design. If any connection is seen at least the slightest crack or other defect, self-made ovens on waste oil can not be used. After all, a mixture of air with oil vapors burns inside, this flame is very dangerous in uncontrolled conditions, besides it is much hotter than from conventional firewood. This is without mentioning that the oven can start to smoke because of a defect. Therefore, you should carefully monitor the design, periodically inspecting the entire unit.

Everything that concerns self-made ovens on waste oil is detailed here. It is told, from what they are more convenient and better to do, and what they are in general. What is very important, here is represented the scheme of the furnace on the waste oil, which can perfectly help to understand all the subtleties of its design. For those who want to create a unit with a drip oil supply, a method of self-made additions to the product is also described.
