Waste oil boiler: a reliable and budget option for room heating
An advantageous option for supplying heating to the 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 to save additional money. If this possibility is excluded, you can purchase a boiler at the factory assembly testing. Currently, the product range is presented in a wide variety.
What is a waste oil boiler
Today, the heating equipment that operates on the development is very popular. This is explained by a number of distinctive advantages of the device. First of all, it is the low cost of installation and the availability of fuel, which can be bought for a nominal fee. Heating at the test site does not need to use resources in the form of electricity and gas, which makes it economically profitable.
Important! The secondary use of waste products in full has a beneficial effect on the environment, excluding the disposal of oil and its ingress into the ground and into reservoirs.
With the correct setting of the boiler, 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 contributes to a rapid increase in room temperature.
Despite the numerous advantages, the boiler has disadvantages during working out. During operation of the device, moisture evaporates from the air and oxygen is burned, which negatively affects human health. Therefore, the boiler should be located in an uninhabited room with a good ventilation system. Devices in the process of testing are quickly polluted. This is especially true for the plasma bowl and the chimney.
For such a boiler, different variants 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 changed as contamination occurs.
How does the boiler work on working out
Boilers for a private house on used oil, as well as for a garage, workshop or production premises have a simple design. They consist of two chambers-compartments: an evaporative and a combustion chamber. In the first compartment, the process of preparing the waste oil for gorenje is carried out. In the second, it is burned. The principle of operation of the device is as follows.
From the waste oil tank, the pump supplies the substance to the evaporation chamber, which is located at the bottom of the apparatus. It maintains the necessary temperature sufficient for heating and subsequent evaporation of the waste. 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 duct to the chamber, where it is mixed with oil vapor. The resulting mixture burns without residue.
The heat exchanger distributes the resulting heat. The formed combustion products enter the chimney. A mandatory process is the preheating of the working out. The oil contains many impurities, under the influence of a certain temperature, the process of decomposition of the substance into simple carbons occurs, which are subsequently burned. As a result, water vapor, nitrogen and gas are formed, harmless to the body.
Complete oxidation of carbohydrates is possible only at a temperature of 600 ° C. If this value is not observed, a lot of toxic substances are formed during the combustion process, which are extremely dangerous to human health.
Types of waste oil oil boilers
There are three variants of waste oil boilers: water heating, heating and household. The first option is an alternative to a modern boiler. Having a platform design, the device warms 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, so if necessary, it is recommended to dilute it with cold.
For hot water boilers on waste oil, a water tank with a volume of no 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 wicky. The first option is used to heat completely cold water. The wick mode allows the water in the tank to be in a heated state. However, this will require a large amount of fuel resource.
Important! Oil water heaters are installed in basements during development, since they are non-transportable.
Domestic boilers are considered an ideal solution for country houses. They have a built-in gas purification mechanism, which contributes to the operation of the device without smoke. Such devices are mobile structures, which will allow them to be transferred to any place without disrupting the performance of the product. This multifunctional device allows not only to heat the room, but also to heat food. The unit can be used outdoors or while traveling.
Automation for a waste oil boiler can perform various functions. Here you can set up control over the heating of the coolant, the temperature of the air in the room. Such devices are installed on the floor. Their cost depends on the functional features of the device.
Characteristics of the waste oil heating boiler
The waste oil heating boiler should be located in an uninhabited room. As a rule, it is installed in a special extension to heat the house. Despite the fact that modern devices are equipped with an advanced 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, the coolant is circulated in the form of ordinary water in the circuit.
The principle of operation of the device is as follows. In the combustion chamber, oil vapors and air masses are oxidized, which come under the influence of a ventilated compressor. The fire level is regulated by means of a hose with a valve. The ventilating device is the only movable element, as a result of which it may fail.
Such boilers are characterized by high productivity and the ability to maintain indoor air temperature for a long time. The fuel tank is located on the floor, and the air heater can be mounted on the wall or ceiling.
The subtleties of the process of creating a boiler on working out with your own hands
The most important component of the fuel combustion process is the preheating of the working out. This will allow the heavy substance to oxidize into light components. This result can be achieved by creating a thick-walled hot bowl made of metal, where the working will be fed in drops.
When oil gets on the hot metal, the substance turns into vapors, which are discharged into the combustion chamber. There they must mix with the air for better gorenje, which is used for the duct. It is equipped with an impeller, thanks to which the flow is swirled, which contributes to a long stay in the combustion chamber of the oil-air mixture. Only in this case the fuel will burn completely.
To carry out the heating process of the evaporation bowl, a wick soaked in fuel should be placed in it. Next, a little diesel fuel or gasoline is added and the 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 boiler on waste oil.
If the oil flows in a jet stream, the fuel will not have time to burn. As a result, toxic components that are dangerous to human health are formed. To carry out effective gorenje without smoke, it is necessary to organize a drip fuel supply. To do this, a hose is used, at one end of which a filter is installed. It is better to use a full filtration automotive oil element. Then a fragment of a medical dropper with a regulator wheel is put on the hose. The element is fixed on the fitting. The oil from the dropper is sent to the funnel, which is connected to the pipe. It supplies fuel to the combustion bowl.
Making a waste oil boiler with a water circuit with your own hands
Based on the study of the drawing of the boiler with their own hands, the following necessary materials and tools are prepared on used oil:
