Do-it-yourself drip-type furnaces are often made by craftsmen and home craftsmen. These installations act as an excellent way of autonomous heating. If there is a desire to use equipment that is one of the cheapest to operate, then it is worth making just such an oven. Used oil can be used as fuel, which can be engine or transmission oil.
Any craftsman can make such a design, due to the simplicity of the work, during which there is no need to use a special set of tools and materials.
Design Features
Do-it-yourself drip-type furnaces are made on the basis of two combustion chambers, which implies the combustion of fuel twice during the operation of the structure. In the first chamber of this type of installation,the process of burning waste oil, which is accompanied by the release of a significant amount of combustible vapors. As soon as these vapors arise, they enter the second compartment, in which oxygen and combustible gases are mixed. The resulting mixture begins to burn in the second chamber, which is accompanied by exposure to significant temperature and the release of a large amount of heat.
When making a do-it-yourself drip-type furnace, you need to choose the right place for its installation. Due to the fact that the operation of the structure is accompanied by the combustion of fuel at rather high temperatures, it is necessary to take care of the safety rules that do not involve the installation of the structure in a place that is blown through.
Maintain normal operation
In order for the unit to work properly, it is necessary to ensure the supply of oxygen to both combustion chambers. An excessive amount of air should not enter the first compartment, and in order to regulate its supply, a damper should be mounted. The second chamber must receive enough oxygen. To do this, many holes must be drilled in the pipe that mates the two compartments, each of which should be approximately 10 mm in diameter.
Oven accessories
When making a do-it-yourself drip-type furnace, you must remember that it can be supplemented with some elements. This will allow you to usedesign for heating several rooms at once. The stove will have such functionality if it is connected to the heating system. Initially, it is necessary to install a tank for heating water, which must be connected to the system, only after that the return line is connected. Thus, the installation will not only be able to heat the premises, but also allow you to heat water, as well as cook food. A design of this type has many advantages, one of which is expressed in small dimensions, which make it possible to dismantle the furnace in a short time, and then install it in another place. It is imperative to supply home-made furnaces for working out a drip type with your own hands with a chimney, the height of which should not be less than 4 m. Make sure that the chimney is devoid of horizontal sections. In order to be able to clean the pipe, which will have to be done once a week, you need to provide the element with a system that will allow dismantling.
Manufacturing options for drip ovens
When making a do-it-yourself furnace for working out, the drawings of which are presented later in the article, you must first think about what design it will have. Thus, the basis of the structure can be steel or a gas cylinder. Before manufacturing, it is worth evaluating that dripping is quite difficult to implement on your own. If the burner is insensitive to impurities that may be contained in used oil, then the drip mechanism, on the contrary, is extremely sensitive. Forto reduce sensitivity, a filter should be put on the hose, it is permissible to use the one used in cars.
The pump can also be borrowed from the car, you can apply the high pressure gasoline pump. Due to the fact that it will apply significant pressure, it is necessary to make a return line, so the excess amount of oil will flow back into the tank. In the role of a dropper, you can use a medical one. It has a clip, this will allow you to adjust the intensity of the feed.
Preparation before production starts
If you decide to start making a furnace for working out with your own hands, you should first consider the drawings and prepare the one for which the work will be carried out. To carry out the process, the master must first prepare some materials and tools:
- grinder;
- pump;
- gas bottle;
- pipe;
- steel sheet;
- dropper;
- welding machine;
- oil container.
Kiln making process
The most suitable option for manufacturing is considered to be a gas cylinder, which has thick walls. But if you use sheet steel, firstly, you have to look for one that has sufficient thickness, and secondly, it will be necessary to perform an impressive amount of welding work, which will make manufacturing more laborious. Don't forget aboutthat the first chamber will work normally if it has a damper necessary to regulate the supply of oxygen - this is the only way furnaces are made for working out with their own hands. Drawings (it’s easier to calculate the furnace from a gas cylinder) you should first prepare and choose the one that will be most convenient to work with.
Cleanable
It is definitely worth remembering that the chamber where the oil is burned must be made such that it can be disassembled during operation, this is the only way it will be possible to facilitate cleaning. Horizontal sections of the chimney are not needed, since draft can be worsened from them, in addition, there should be a minimum number of inclined ones. It is preferable to make the pipe vertical.
Balloon manipulation
When making a furnace for working out with your own hands, drawings (from a gas cylinder) will allow you to do the work correctly. So, initially the balloon has to be prepared, only after that you can start cutting off the top and bottom from it. In order to install the oven and make it stable, legs must be welded to its lower part, which are prepared from cut off parts. Next, you can proceed to the manufacture of the combustion chamber, which should turn out to be collapsible. A hole is made in this compartment, into which a tube is installed, through which the supply of fuel and oxygen will be regulated.
In the center you need to weld a pipe withholes made. This element will connect two compartments, in each of which combustion occurs. The second compartment can be made from the middle part of the product and a sheet of steel. After the chamber is ready, it will have to be strengthened by using a welding machine to the pipe from above. After the chimney is made and mounted.
After making a do-it-yourself furnace, the photo of which is presented in the article, it must be checked for functionality. However, do not immediately fill the entire compartment with oil, as well as throughout the entire period of operation, this will prevent splashing of oil from the combustion chamber. Pour it only 2/3 of the volume.
Recommendations for working with the balloon
If you decide to start making a drip-type furnace with your own hands, the drawings will definitely come in handy for you. It is important to know how to work with the cylinder, otherwise an explosion may not be avoided, because even if the product has not been used for a long time, gas can remain in it, which is dangerous. Initially, the valve should be removed from the cylinder by screwing, after which the cylinder should be freed from gas residues. Then water is poured into the hole, only after that you can start working with a grinder, which will allow you to rid the product of the upper part with a hemisphere. At the next stage, the master will have to separate the same area from the bottom of the product. You should not start cutting the balloon if you have not completed all the above steps.
When making a do-it-yourself drip-type furnace from a gas cylinderyou should get two hemispheres, which should be welded using the circumferential seam method, this will form the first compartment. In this case, the lower section with the stand should be left below. To the upper part, which also has the shape of a hemisphere, a pipe should be welded over the hole, which has a perforation. Through this channel, gases will rise into the second compartment, mixing with air in parallel. This indicates the need for a fairly thick perforation.
After the lower chamber is prepared and the adapter in the form of a pipe is mounted, you can start manufacturing the upper chamber. Its assembly is made from the middle part of the product, however, before that, the ends of the cylinder should be blocked using sheet steel. In this case, the master must prepare an entrance for installing a perforated pipe in the lower “cover”, and a hole for mounting a chimney pipe in the upper one.
In conclusion
Drip-type furnaces are very economical, and you don't even have to buy fuel for them, especially if you are a motorist. That is why such equipment acts as the best for heating a garage or industrial premises.
