Important!Before you pour the oil into the system, it should be filtered.

Principle of operation furnace waste oil

The prototype for oil furnaces operating waste oil is kerosene stove, which has been used previously in villages and cottages. As a fuel there was used kerosene, which couples the afterburning in a separate chamber. To save on fuel, it was developed variant of the waste oil combustion. It is available for free or for a reasonable price at any service station.

Creating a homemade stove to working out is not a difficult process. The main objective is to correct organization of productive systems for oil combustion process. To ensure complete combustion of heavy vapor components must be pre-split into light that occurs as a result of pyrolysis. For efficient evaporation is carried proper heating oil.

The operating principle of an oil furnace at working out is as follows. In the first place in the lower chamber of the device is performed ignition mining. The intensity of burning is regulated by the throttle body of the device through which air enters the chamber. Oil vapor mixed with oxygen, the vertical pipe move upward. The pipe is connected to the upper tank, which is the afterburner.

The mixture was stirred under the influence of the Coriolis force (inertia force). The intensity of the process is achieved by the best one of the combustion chamber diameter and length. To ensure complete combustion air through the valve must act in sufficient quantity. For this purpose it is further sucked through the holes made in the perforated vertical pipe connecting tanks.

gas flow is directed to the final post-combustion chamber, in which the upper part extended. At its manufacturing runs horizontal spacing between the inlet flue and the outlet of the combustion chamber, necessary to ensure that the temperature jump between zones oxide of nitrogen and oxygen afterburning. When set to a temperature below 600 ° C nitrogen oxides are active oxygen. Decomposing, they oxidize fuel particles. As the temperature increases in the oxygen acts as the primary oxidant. Harmful substances are discharged through a chimney to the atmosphere.

Important!To ensure effective oil combustion temperature in the upper tank must be low.

Furnace waste oil: Variety of designs

There are several varieties of oil furnaces, which operate on waste oil. Classical model is a pyrolysis unit. It is made from the finished containers as barrels, tubes, cylinders or sheets of the alloy. The bottom vessel filled with oil, which was cleaved with insufficient air. The upper tank is intense combustion of vapor, whereby a lot of heat.

Temperature control is performed air supply. Such a furnace requires constant cleaning chambers of the accumulated fraction. It is no mechanical temperature control.

At fuser oil on the working off is implemented by a fan guaranteed air supply to the second chamber. The combustion process takes place more efficiently, so that warm air evenly into the room.

The operating principle of the stove with a drip feed of fuel is similar to the mechanism of diesel engines. It is characterized by efficiency. However, an independent manufacturing process of the device is very time-consuming, so it is best to purchase the plant device of this type. Moreover, it should be noted that improvised stove finicky to drip oil quality, which before being fed to the furnace must be preheated.

The most efficient model is the furnace waste oil supercharged. It compared with a bourgeois, it has a higher cost. Additional heat is supplied from the blowing fan. Aspiration can be performed using the motor of car cooler and heater blowing propeller will provide a home 220V power

Requirements for the installation and operation of the furnace in butter

It is required that the oven is in an empty room, near which should not be flammable surfaces. Particular attention is paid to individual processing devices. They can not be put on a shelf or other support that can catch fire.

Homemade oven for working out should be placed on a level surface, which may be concrete or brick. It is necessary that the distance between the machine and the wall there is at least 1 m. In order to form a good chimney draft should have a length of more than 4 m. On its outer side should provide insulation to prevent condensation acids.

The composition of the waste oil must not reach a flammable solvent or other element, so that such components should be kept away from the furnace. Also unacceptable ingress of moisture into the oil container. This will result in the ignition furnace. In case of emergency to eliminate the fire extinguisher should be used.

Important!In the room where the stove is located, a good system of natural ventilation should be organized.

Before working oil is poured into the vessel in an amount equal to half of the volume of the tank, which will provide the necessary space for the formation of vapor. To pair enriched with oxygen, it is necessary to wait some time. Then produce fuel ignition via long matches. As soon as the vapor ignition process, the shutter is half covered.

To improve efficiency mini-oven for possible working off over its upper sealed chamber to establish the fluid tank. For supplying and discharging the water fittings attached thereto, are placed at different levels. Another option for improving performance is required convection of air, which is carried out by a fan, positioned near the upper chamber. Taking warm air from the stove, it contributes to its cooling, which has a positive effect on the term of operation of the device.

Options to improve the efficiency of the mini oven with his own hands

Furnaces for waste oil are often used to heat the garage or small workshop. The building is permanently occupied by people who use such a device is not recommended. This is due to the fact that the oven absorbs oxygen, which has a negative effect on the respiratory organs. If the machine is intended for heating residential premises, it must be located in a separate room.

To improve the efficiency of the additional devices may be used apparatus. Furnace waste oil with a water circuit organized by strapping coil mounting housing or the water jacket on the chimney. In the first case the coil is made of copper pipe. It is embedded in the home heating system.

The water jacket is made of sheet metal in the form of a vessel which is located at the top of the housing. It is circulated liquid coolant. For efficient operation of the furnace in the reservoir should be up to 30 liters of water. Such an apparatus allows to heat the room a large area.

Oven for working out a water circuit must be equipped with an expansion tank with an emergency drain, required in the case of boiling fluids. It is not recommended to install a membrane tank.

Another embodiment of increasing the effective operation of the furnace is to use air heat exchanger, which is represented by a fan. The machine has no structural changes are made, and the heating of the room is improved. The fan is located near the top of the camera. When it cools the heated air is distributed by the floor area. It is also possible drive the air through the duct, located on top of stove, or through a pipe, which is mounted in the afterburning chamber.
