Waste oil boiler: a reliable and budget option for heating a room

An advantageous option for supplying heating to a room and providing hot water is a waste oil boiler. The device is characterized by a simple design, which allows you to make it yourself. This will help you save additional money. If such a possibility is excluded, you can purchase a boiler at the factory assembly. Currently, the range of products is presented in a wide variety.

Different variants of waste oil can be used for the boiler, which is characterized by an abundance of various impurities

What is a waste oil boiler

Today, heating equipment that operates during testing is very popular. This is due to a number of distinctive advantages of the device. First of all, this is the low cost of installation and the availability of fuel, which can be bought for a nominal fee. Heating at mining does not require the use of resources in the form of electricity and gas, which makes it economically viable.

Despite its many advantages, the mining boiler has its drawbacks.

Important! Recycling of waste products in full has a beneficial effect on the environment, excluding the disposal of oil and getting it on the ground and into water bodies.

If the boiler is set up correctly, the waste oil is burned completely, so that no toxic combustion products are formed. The device consists of a minimum number of parts, which can be seen on the boiler diagrams. This increases the reliability and durability of the structure. It does not take much time to warm up the boiler. Forced convection causes the room temperature to rise rapidly.

Despite its many advantages, the mining boiler also has disadvantages. During operation of the device, moisture from the air evaporates and oxygen is burned, which negatively affects human health. Therefore, the boiler must be located in a non-residential area with good ventilation. The mining devices quickly get dirty. This is especially true for the plasma bowl and chimney.

For such a boiler, different versions of waste oil can be used, which is characterized by an abundance of various impurities. Therefore, to ensure a long period of operation of the device in the place where the oil is supplied to the boiler, a filter should be installed, which must be replaced as it becomes dirty.

The waste oil boiler must be located in a non-residential area with good ventilation.

How does a boiler work

Waste oil boilers for a private house, as well as for a garage, workshop or industrial premises have a simple design. They consist of two chambers-compartments: an evaporation chamber and a combustion chamber. In the first compartment, the waste oil is prepared for combustion. In the second, it is burned. The principle of operation of the device is as follows.

From the container with the used oil, the pump delivers the substance to the evaporation chamber, which is located in the lower part of the apparatus. The required temperature is maintained in it, sufficient for heating and subsequent evaporation of the mining. Oil vapors rise to the upper area of ​​the housing, where the combustion chamber is located. It is additionally equipped with an air duct in the form of a pipe with holes. With the help of a fan, air is supplied through the air duct to the chamber, where it is mixed with oil vapor. The resulting mixture burns out without residue.

The heat exchanger distributes the heat received. The generated combustion products are fed to the chimney. A mandatory process is the preheating of the mining. Oil contains many impurities, under the influence of a certain temperature, the process of decomposition of the substance into simple carbons takes place, which are subsequently burned. As a result, water vapor, nitrogen and gas are formed, which are harmless to the body.

Waste oil boilers have a simple design

Complete oxidation of carbohydrates is possible only at a temperature of 600 ° C. If this value is not observed, the combustion process produces many toxic substances that are extremely hazardous to human health.

Varieties of waste oil boilers

There are three options for waste oil boilers: water heating, heating and household. The first option is an alternative to a modern boiler. Having a platform design, the device heats up a flat surface where the water tank is located. A small pump is installed at the outlet of the tank, which regulates the pressure in the system.

Important! It is very difficult to change the temperature of the water, therefore, if necessary, it is recommended to dilute it with cold water.

For hot water boilers using waste oil, a water tank with a volume of not more than 140 liters is used. It heats up for 2 hours, which is several times faster than the speed of a modern electric boiler. The oil water heater can operate in two modes: fast and wick. The first option is used to heat completely cold water. The wick mode allows the water in the container to be warmed up. However, this will require a large amount of fuel resources.

Important! Oil-fired water heaters for mining are installed in basements, as they are not transportable.

Domestic boilers are considered the ideal solution for country houses. They have a built-in gas cleaning mechanism, which makes the device work without smoke. Such devices are mobile designs, which will allow them to be carried to any place without disrupting the operation of the product. This multifunctional device allows not only heating the room, but also heating food. The unit can be used outdoors or while traveling.

Waste oil boiler automation can perform various functions.Here you can set up control over heating of the coolant, room temperature. Such devices are installed on the floor. Their cost depends on the functional features of the device.

Due to the compact dimensions of the hot water boiler, it is convenient to install it in the boiler room

Characteristics of a waste oil heating boiler

The waste oil boiler must be located in a non-residential area. As a rule, to heat the house, it is installed in a special annex. Despite the fact that modern devices are equipped with an improved filtration unit, they emit an unpleasant smell of engine oil during operation.

The inner part of the unit is equipped with a heating unit with a water tube and a hydraulic pump. The last element can work from the electrical network or from the energy generated by the device itself. With the help of a hydraulic pump, a coolant circulates in the circuit in the form of ordinary water.

The principle of operation of the device is as follows. In the combustion chamber, the oxidation of oil vapors and air masses, which come under the influence of a ventilated compressor. The fire level is regulated using a hose with a valve. The ventilation device is the only movable element, as a result of which it can fail.

Such boilers are characterized by high performance and the ability to maintain the air temperature in the room for a long time. The fuel tank is located on the floor, and the air heater can be mounted on a wall or ceiling.

The subtleties of the process of creating a boiler for working out with your own hands

The most important component of the fuel combustion process is the preheating of the mining. This will allow the heavy substance to oxidize into light components. This result can be achieved by creating a thick-walled red-hot metal bowl, where the mining will be fed in drops.

When oil hits a hot metal, the substance turns into vapors, which are discharged into the combustion chamber. There they must mix with air for better combustion, for which an air duct is used. It is equipped with an impeller, due to which the flow is swirled, which contributes to a long stay of the oil-air mixture in the combustion chamber. Only in this case the fuel will burn out completely.

To carry out the heating process of the evaporation bowl, a wick soaked in fuel should be placed in it. Then a little diesel fuel or gasoline is added and ignition is performed. When the metal is heated to the desired temperature, oil is supplied. This process is simple but very dangerous. Therefore, it is important to properly organize the flow of the substance into the nozzle for the waste oil boiler.

When oil hits a hot metal, the substance turns into vapors, which are discharged into the combustion chamber

If the oil flows in a jet, the fuel will not have time to burn. As a result, toxic components are formed that are dangerous to human health. For efficient combustion without smoke, a drip fuel supply should be organized. For this, a hose is used, at one end of which a filter is installed. Better to use a full filtration automotive oil element. Then a fragment of a medical dropper with a control wheel is put on the hose. The element is fixed to the union. The oil from the dropper is directed into a funnel, which is connected to the pipe. It supplies fuel to the combustion bowl.
