A profitable 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 you save additional money. If this possibility is excluded, you can purchase a boiler for factory assembly testing. Currently, the product range is presented in a wide variety.

The boiler can use different types of waste oil, which is characterized by an abundance of various impurities

What is a waste oil boiler?

Today, heating equipment that operates during mining 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 purchased for a nominal fee. Exhaust heating does not require the use of resources in the form of electricity and gas, which makes it economically profitable.

Despite its many advantages, the boiler during development also has its disadvantages

Important! Recycling waste products in full has a beneficial effect on the environment, eliminating the disposal of oil and its release onto the ground and into water bodies.

When the boiler is set up correctly, the waste oil is burned completely, which prevents the formation of toxic combustion products. The device consists of a minimum number of parts, which can be seen in boiler diagrams. This increases the reliability and durability of the structure. It does not take much time to heat up the boiler. Forced convection helps to quickly increase the temperature in the room.

Despite its many advantages, the boiler during testing also has disadvantages. When the device operates, moisture evaporates from the air and oxygen is burned, which negatively affects human health. Therefore, the boiler should be located in a non-residential area with a good ventilation system. Devices during mining quickly become dirty. This especially applies to the plasma bowl and chimney.

For such a boiler, different types 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, a filter should be installed in the place where oil is supplied to the boiler, which must be changed as it becomes dirty.

Waste oil boiler

I bought this boiler two years ago, started it up, set it up for a long time, and still smokes. A few days later, the gears in the oil pump broke, they turned out to be plastic, they restored it with their own hands, and converted it from the oil pump of a Ural motorcycle. Manufacturers are not very responsive, I would even tell them about our problems. Further, after the boiler had been running for about 10 hours, there was a power outage, and then the complete breakdown came... accordingly, after the shutdown, the automation and the fan that supplied air turned off, after a minute the boiler began to fire like a cannon, throwing out flames through the hole through which air was supplied from the fan, after the first shot, a flame of 1.5-2 meters passed 20 cm from my face and it continued shooting for about 10-15 minutes until the oil burned out and the boiler went out, fortunately there was nothing flammable nearby. Can you imagine my state at that moment, because I could have remained disabled and only by a lucky chance my face was not in front of the flame, this shot could even have killed me. I call with a complaint, they tell me, probably your hood is bad, they say the pipe is low, my pipe is 1.5 meters higher than the ridge of my building, the building is two-story, approximately the height of the pipe is 14 meters, the pipe is insulated with mineral wool and sheathed with galvanized sheet, that is, everything is as it should be. At that moment, the month of December, I was doing finishing work and desperately needed heat, I heated the first floor with a diesel gun, and the second floor with two gas guns, it took a lot of gas and diesel fuel and it was expensive. It was planned to use the oil recovery boiler in parallel with the gas boiler, and there would be some savings, so a car service center was planned on the first floor, and an administrative center on the second. Conducting gas is not an easy task, and it takes a long time, and I didn’t want to curtail the finishing work, so having calmed down a little from the shots, a week later I decided to start the boiler again, but now I realized that the battery must be connected in parallel to avoid the It was after a power outage. I lit the boiler, started it up, everything worked, but then a curious plumber, who came to check the batteries and the entire heating system that they had installed, decided to look into the firebox, opened it, and a flame began to come out from there, after which the flames were drawn into the boiler and suddenly splashed everything out through the firebox along with the oil and it all caught fire on the walls and on the floor, fortunately a bucket of water and a fire extinguisher were nearby and fortunately this burning oil did not splash out on that plumber. Here’s the story... I bought a boiler for 80,000 rubles, paid about 5,000 rubles for delivery to Tatarstan, now this boiler has been standing for two years as an exhibit and reminds me that I shouldn’t mess with uncertified homemade products and such charades as “Stavpech”. They didn’t give any instructions or really explain anything, and they didn’t even hint at warning about those unpleasant situations. I wanted to sue them and contact the police, but construction was in full swing, and I wanted to finish the construction quickly. And after all this, I began to move more actively on the gas. They gave me gas, I heat up without any problems, but I accidentally remembered about this boiler and decided to write to people who are thinking about buying, don’t make mistakes. Remember “Stavpech” is bad...

How does an exhaust boiler work?

Boilers for a private home using waste oil, as well as for a garage, workshop or industrial premises, have a simple design. They consist of two chamber compartments: an evaporation chamber and a combustion chamber. In the first compartment, the process of preparing used oil for combustion is carried out. In the second, it is burned. The principle of operation of the device is as follows.

From a container with used oil, the pump supplies the substance to the evaporation chamber, which is located in the lower part of the device. It maintains the required temperature, sufficient for heating and subsequent evaporation of the waste. Oil vapor rises to the upper zone 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. Using a fan, air is supplied through an air duct into the chamber, where it is mixed with oil vapor. The resulting mixture burns without a residue.

The heat exchanger distributes the resulting heat. The resulting combustion products enter the chimney. A mandatory process is preheating of the waste. Oil contains many impurities; under the influence of a certain temperature, the substance decomposes into simple carbons, 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 dangerous to human health.

Types of waste oil boilers

There are three options for waste oil boilers: water heating, heating and domestic. The first option is an alternative to a modern boiler. Having a platform design, the device heats up the 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 water.

For water heating boilers using waste oil, a water tank with a volume of no more than 140 liters is used. It heats up within 2 hours, which is several times faster than the operating speed of a modern electric boiler. An 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 heated. However, this will require a large amount of fuel resource.

Important! Oil water heaters during mining are installed in basements, since they are non-transportable.

Domestic boilers are considered the 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 moved to any place without affecting the functionality of the product. This multifunctional device allows you not only to heat the room, but also to heat food. The unit can be used outdoors or while traveling.

Automation for waste oil boilers can perform various functions. Here you can set up control over the heating of the coolant and the air temperature in the room. Such devices are installed on the floor. Their cost depends on the functional features of the device.

Due to the compact size 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 heating boiler must be located in a non-residential area. As a rule, to heat a house it is installed in a special extension. Despite the fact that modern devices are equipped with an improved filtration unit, during operation they emit an unpleasant odor of machine oil.

The inside of the unit is equipped with a heating unit with a water tube and a hydraulic pump. The last element can operate from the electrical network or from the energy generated by the device itself. Using a hydraulic pump, the 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, oil vapors and air masses, which enter under the influence of a ventilated compressor, are oxidized. 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 may fail.

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

The best known manufacturers and models: characteristics and prices

DanVex B-30

One of the best Finnish-made boilers for heating a private house. In addition to the 35.6 kW version, there are also other versions with a heating capacity of 60-220 kW. It is distinguished by high reliability, a well-thought-out system to simplify maintenance and cleaning (for example, an increased diameter of the firebox and smoke pipes, a vertical chimney, so that soot pours into the ash pan, a door that opens with the burner, so access to the combustion chamber is achieved by pressing the handle).

The boiler is also known for its compact size, functional automation with the ability to connect a GSM module and one of the highest efficiency for this type of boiler - 88%. Fuel consumption at maximum load is 3.3 l/h. The model has all the necessary protective functions and modes, the ability to connect a room thermostat and external temperature sensors.

The only known disadvantages are noisy operation, the absence of a fuel pump, heavy weight (157 kg) and an unreasonably high price. Country of origin: Finland.

NORTEC B70 (WB 40)

Model from a Russian manufacturer with a power of 40 kW. In terms of design and principle of operation, it does not differ from the above-mentioned Finnish analogue, it is equipped with the same heat exchanger made of heat-resistant steel, is less convenient to maintain, inferior in quality of materials and assembly, has larger dimensions and less functional controls.

However, it also has significant advantages in the form of a much lower cost, a full-fledged fuel unit (pump, filters, tank) included with the boiler, and the ability to operate on a large number of fuels (fuel oil, crude oil, heating oil).

EcoBoil-18

Vertical drip type model made in Russia with a power of 15 kW. The distinctive features of the model are its extremely low cost, compact size, reliability and the presence of an oil pump included. In addition to mining, it is capable of burning kerosene. The model is equipped with one of the best automatic control units in the drip oil boiler segment, but the automation is still inferior to standard models that spray fuel.

Also known disadvantages are the need for daily cleaning and domestic build quality. According to installation practice and owner reviews, in all cases the model has been working without problems for more than 7 years.

Cost : 36,800-39,900 rubles.

Furnace KDO-2

Another domestic drip-type model with a power of 28 kW. The boiler has the same design and operating principle as EcoBoil, but has a higher cost with less functional automation. The advantage is the removable pyrolysis bowl (in which the oil evaporates), this makes it easier to clean, and in case of burnout it can be easily replaced.

Cost : 44,500-50,000 rubles.

Subtleties of the process of creating a boiler for testing with your own hands

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

When oil hits hot metal, the substance turns into vapor, which is 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, thanks to which the flow swirls, which contributes to a long stay of the oil-air mixture in the combustion chamber. Only in this case will the fuel 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 or gasoline is added and ignition is performed. When the metal heats up 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 a waste oil boiler.

When oil hits hot metal, the substance turns into vapor, which is discharged into the combustion chamber

If the oil flows in a stream, the fuel will not have time to burn. As a result, toxic components are formed that are hazardous to human health. To achieve efficient combustion without smoke, a drip supply of fuel should be arranged. 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 wheel-regulator is put on the hose. The element is fixed to the fitting. The oil from the dropper is directed into a funnel, which is connected to a pipe. It supplies fuel to the combustion bowl.

Helpful advice! To make it easier to create a homemade boiler for mining, you can use ready-made barrels for oxygen or propane.

The boiler body is conventionally divided into two parts. The heating radiator will be located at the bottom, and the water jacket will be at the top.

The process of making a boiler with your own hands using waste oil begins with the manufacture of an internal tank in the form of a container with a water jacket, a channel for oxygen supply and an oil pipe.

The boiler body is conventionally divided into two parts: radiator and water jacket

The dimensions of the tank elements are marked on a sheet of metal according to the drawing of the waste oil boiler. All parts are connected by welding. At the bottom of the housing there is a door for removing the bowl and igniting the oil. To speed up the process, the body can be made from a fragment of a pipe with a diameter of 500 mm and a length of 1 m.

Two round-shaped elements are cut out of metal plates, which will serve as the bottom and cover of the case. A round hole is made in the upper part, the size corresponding to the diameter of the perforated pipe into which it is inserted and welded. The body is covered with two plates by welding. Legs made of reinforcing bars are attached to its bottom.

The upper tank is made in a similar way. There is a hole in the lid for the chimney. To connect two containers, a burner tube with a diameter of 100 mm and a height of 35 cm is used. Holes with a diameter of 9 mm in the amount of 50 pieces are made in it. over the entire area of ​​the product.

Oil options for waste oil boilers

Any type of waste oil can be used for these boilers. Not only machine ones are considered suitable, but also shock-absorbing, transformer, transmission, motor, hydraulic, rapeseed, vegetable and other types. The main requirement for fuel is the absence of water, flushing fluids, antifreeze and other undesirable components in its composition. Machine oil is the cheapest and most accessible option. It can be purchased in sufficient quantities at any service station.

Any type of waste oil can be used for boilers

A diesel fuel boiler is characterized by maximum efficiency. Oily substances can be added to it, which will act as a catalyst, which promotes a good combustion process. This could be fuel oil, kerosene, or barbecue lighter.

It is strictly forbidden to use alcohol, gasoline and other flammable substances as fuel for exhaust boilers.

Important! During combustion, fuel must not be added to containers. It is filled only after the fill has completely burned out and the tank has cooled down.

Advantages and disadvantages of oil boilers

The use of waste oil as fuel has clear advantages:

• Economical. Used oil is a recyclable material, the price of which is several times lower than that of other types of fuel. You can buy it at enterprises with a large number of cars, service stations and even in private garages.
• Autonomy. You do not depend on the gas pipeline, and when installing a battery, on electricity. This allows you to heat rooms located far from civilization.
• Simplicity of design. Reliability and durability of operation are ensured by the simplicity of the device and the predictability of the operating principle. With proper use and regular cleaning, the device has a long service life.
• Fast heating time. Already in the first minutes of work you will feel the temperature increase. This is especially noticeable when using air heating devices such as heat guns.
• Fire safety. Used oil itself is not flammable. This simplifies storage conditions and increases safety during use.
• You can install such equipment yourself; you will not need additional permits or the services of specialists, as is necessary if you install a gas boiler.
• If you suddenly run out of fuel, you can heat it with another type of liquid fuel. To do this, you will need to change the settings and in some cases replace the injector.

However, this heating method has its disadvantages:

• Regular cleaning required. Since initially unrefined fuel is used, it contains a number of unnecessary impurities that clog the device components. For a longer service life, it is important to clean it regularly.
• Search for fuel. Before purchasing this type of boiler, you need to look at what sources are available in your area. Compared to other fuels, used oil is more difficult to find.
• At low temperatures, oil freezes. This leads to the need for a special room for storing waste during the cold season.
• Initially, the cost of such equipment is high.
