Liquid fuel heating boilers: design, types, review of popular models

An oil-fired liquid fuel boiler is designed for heating residential buildings or technical buildings in areas without a centralized gas supply. The burner can use used engine oil, which reduces the cost of operating the equipment. The design includes a control unit that supports specified operating parameters or allows you to change settings remotely (for example, using a smartphone).

An oil-fired boiler runs on fuel.

Features of liquid fuel boilers

Oil-fueled boilers are characterized by compact dimensions and increased efficiency, reaching 95%. The burner installed inside allows you to adjust the combustion intensity using automation.

A number of manufacturers allow switching installations to gas, which is supplied centrally or from cylinders equipped with a reducer to normalize pressure.

Functions

The equipment allows:

• warm up the coolant circulating in the heating system;
• provide a private home with hot water.

Operating principle

Liquid fuel is supplied to a nozzle equipped with a fan. The air flow atomizes the fuel; the resulting mixture burns in a special chamber, the walls of which have channels for the circulation of water or antifreeze. The gas flow passes through the heat exchanger, increasing the efficiency of the boiler, and is then released into the atmosphere through the chimney. The fuel supply intensity and boost pressure are regulated by the electronic unit, taking into account the programmed program.

Construction of a liquid fuel boiler.

Areas of use

The equipment is used in buildings located at a great distance from main gas pipelines and not connected to central heating lines. The boiler requires constant power to operate.

If the building is not connected to the AC electrical network, then long-term combustion units using wood or coal should be used.

Electric heating devices

Electric boilers are a convenient option for heating small buildings. Most often they are used as additional heating devices. For example, if firewood burns in a solid fuel boiler. As the main source of heating for a private home, electric boilers are used in areas where there is no gas supply. To install them, you do not need to obtain special permits or approvals.

The main advantage of such units is their ease of operation, they do not require frequent maintenance, and are equipped with electronic sensors and temperature programmers.

Heating structure

The boiler is equipped with a metal body, which contains a layer of thermal insulation that does not collapse under the influence of high temperatures. The delivery set includes a fuel tank and hoses for supplying liquid fuel to the burner. Some manufacturers provide for the installation of filters or electric heating elements to ensure reliable operation of the boiler at low air temperatures.

Main nodes

Inside the case there are:

• replaceable burner with electric fan;
• steel combustion chamber with double walls, between which water circulates;
• radiator for additional heating of the coolant;
• round or square channel for removing combustion products into the atmosphere;
• electronic control unit.

Burner

The design consists of a spray head and a casing into which air is supplied under slight excess pressure. The forming combustible mixture is ignited by an electric spark, a current pulse is supplied by the control unit. Continuous flame modulation is provided, which allows reducing liquid fuel consumption and maintaining the specified coolant temperature at the boiler outlet.

The burner consists of a casing into which air is supplied.

The combustion chamber

The combustion of atomized fuel occurs in a separate chamber made of heat-resistant steel. Furnaces are usually divided into categories according to the method of removing oxidation products. Open chambers provide for the release of smoke into the atmosphere due to natural draft. Closed fireboxes are equipped with fans and a smoke exhauster that provide forced removal of combustion products. The walls of the chamber have ducts for the circulation of water, which cools the structure.

Heat exchanger

The liquid from the furnace is supplied to a heat exchanger installed in the path of the flow of heated combustion products. Inside the radiator there are interconnected channels through which water or coolant constantly circulates. For the manufacture of the heat exchanger, cast iron is used, the service life of which reaches up to 30 years, boiler steel with a service life of no more than 10 years, or copper alloys.

To increase operating efficiency, fins are made on the outer part of the radiator and additional tubes are provided to increase the heating area.

Chimney

Since the combustion rate of petroleum fuel is lower than that of solid fuel, the gas exhaust system has additional strokes and plates to slow down the flow. Swirling ensures that the mixture burns out and increases the efficiency of the boiler. The equipment is equipped with steel pipes. For compact installations with low power, coaxial chimneys are used.

The gas exhaust system contains a chimney.

Automation block

The electronic controller maintains the specified parameters and ensures that the fuel supply is turned off when a malfunction is detected. The control system includes sensors that record the operation of the burner, the temperature of the coolant at the inlet and outlet, and the fluid pressure in the circuit. The diagnostic system constantly checks the condition of the boiler components. The fuel supply line has a solenoid valve for emergency stop.

Design and principle of operation of the boiler

Liquid fuel units operate on the same principle as gas units. The main difference is the use of a fan burner (nozzle). The type of device largely determines the efficiency and economy of the boiler.

Our compatriots are considering installing a liquid fuel unit as an alternative heating method in the absence of a centralized gas supply line

Main operating units of the heat generator

Structural elements of a liquid fuel boiler:

• burner;
• the combustion chamber;
• heat exchanger;
• chimney;
• Control block;
• frame.

The liquid fuel heating installation is equipped with a line with a pump that supplies fuel and a tank for storing fuel.

To increase the performance and efficiency of the device, manufacturing companies are improving models by adding different heat exchange plates and chimney tubes to the device.

Heating unit burner

The main module of the installation, which is responsible for preparing the fuel-air mixture and transmitting it in the amount necessary to maintain the operation of the heat generator.

The liquid fuel burner is fan driven. Fuel is supplied and injected into the combustion chamber under pressure - forced air injection is performed

Standard burner equipment for an oil-fuel boiler:

1. Ignition transformer. Generates a spark that ignites the fuel.
2. Control block. Determines the start-up phases, performs control and stops the burner. The connection of a photocell, an ignition transformer and an emergency shutdown sensor is provided.
3. Solenoid valve. Corrects the supply of fuel to the combustion chamber.
4. Air regulator with filter. The device normalizes the air supply, preventing the ingress of solid particles.
5. Preheater. Changes the state of the fuel, reducing its viscosity. The more liquid the fuel enters the nozzle hole, the more economically it is consumed.
6. Fuel overflow pipe. It is connected to the tank where the fuel is heated.
7. Flame pipe. Through the main line, thermal energy is supplied to the place where the coolant is heated, which then circulates in the heating system.

The burner can be initially built into the boiler without the possibility of increasing the power of the unit. Attachable modules allow you to modify the equipment.

Setting up a mounted burner is done by a specialist at home. The advantage of a factory-built module is the quick commissioning of the boiler system

Boiler combustion chamber

Essentially, it is a heat-resistant container with an inlet and an outlet. As a rule, it has a round or rectangular cross-section.

Heat exchanger device

Through the walls of the heat exchanger, thermal energy is transferred to the coolant. In modern models, the coating of this element is made according to the principle of a radiator device - this allows maximum use of the thermal energy obtained during the combustion process.

The burner and door are fixed on the front section of the heat exchanger. The number of sections and the heat exchanger coverage area determine the boiler power

Chimney for liquid fuel unit

Air intake is carried out from the street or from the boiler room, which can be properly equipped in this article.

When supplied from outside, air is supplied through a coaxial chimney or through a separate channel. To increase efficiency, smoke channels are equipped with steel plates - the exhaust gases form turbulent flows, reducing their speed. The traction is maintained.

Device control unit

Automation is designed to maintain the set temperature. Auxiliary functions reduce the cost of boiler operation. From a technical point of view, the most advanced are weather-dependent units that change the heating temperature of the coolant based on the readings of external sensors.

The operating principle of the thermal unit is based on the preparation of a mixture of fuel and air with its subsequent spraying in the combustion chamber

Heating boiler body

All elements of the system are enclosed in a durable heat-insulating housing. This “shell” reduces heat loss and increases the efficiency of the boiler.

The outside of the body is covered with a layer of heat-insulating film, which, when heated, remains cold and protects the operator from burns.

How is the room heated?

The entire process of generating heat in an oil-fuel boiler and transferring thermal energy to heating radiators can be divided into several stages.

Stage 1. Diesel oil or other fuel is poured into the storage facility. The fuel pump supplies liquid to the burner device - pressure is created in the pipeline. At the same time, the fuel pump uses sensors to determine the quality of the fuel and the percentage of its thickening.

Stage 2. Diesel fuel enters the preparation chamber. Here the fuel is mixed with air, heated and liquefied.

Stage 3. The fuel-air mixture is supplied to the injector. Under the action of a fan, the mixture is atomized and the fuel mist ignites in the combustion chamber.

Stage 4. The walls of the chamber heat up. Due to this, the heat exchanger and coolant are heated. The latter enters and circulates in the heating system.

Stage 5. When a flammable substance is burned, gases are formed that are discharged through the chimney. Rushing out, the smoke passes through a series of heat exchange plates and also gives off its heat.

When fuel is burned, soot is formed. To maintain the boiler efficiency at the proper level, the walls of the combustion chamber must be periodically cleaned

Main types and classification

Equipment is usually divided into categories according to a number of characteristics:

• purpose;
• opportunities;
• setting technique;
• heat exchanger material;
• types of fuel;
• number of circuits;
• installation method.

By area of ​​application

The primary classification divides boilers into domestic and industrial. Equipment for houses has a power from 6 to 230 kW and allows you to heat buildings with an area of ​​50 to 2200 m². Boilers for industrial premises have a power of up to 12 MW and can supply heated water or steam under pressure into the mains. Household installations are designed for liquid pressure within 4–6 bar and are equipped with safety valves.

Equipment for houses can heat up to 2200 m².

By functionality

Standard boilers have 1 operating circuit, which is connected to the heating system. An electric boiler is required to provide hot water, but oil-fired units with an additional radiator are available.

The equipment is equipped with separate temperature controllers and maintains heating of the water that is supplied to the washbasins or shower stall.

By regulation method

Boilers can be divided into categories according to the method of setting their operating performance:

1. Single-stage type, providing for turning off and turning on the burner according to signals from the temperature sensor. They are simpler in design, but consume more fuel.
2. Multi-stage type (with 2 or 3 gradations). After heating the coolant to the set value, the combustion intensity decreases, but the flame does not go out.
3. Modulated, ensuring its smooth change. Boilers take into account the temperature inside and outside the house, operating mode and calorific value of the fuel. Due to continuous adjustment, fuel consumption is reduced.

By material type

Classic cast iron radiators have a long service life, but cannot withstand temperature changes at the inlet and outlet of more than 20°C. If the requirements are violated, cracks appear that cannot be repaired. For periodic use, boilers with a steel radiator that is not sensitive to temperature changes are suitable. But with intensive use, the metal burns out in 5–6 years, which is several times less than the service life of a cast iron heat exchanger.

Cast iron boilers have a long service life.

By fuel type

Diesel fuel or used motor oil can be used as fuel for boilers. The first option ensures a reduction in ash deposits, which simplifies the chimney and combustion chamber.

Motor oil is cheaper than diesel fuel, but oxidation produces fine particles that settle on the walls of the firebox and in a separate container in the smoke channel.

By number of circuits

Manufacturers offer boilers:

• with 1 heat exchanger designed for connection to the heating system;
• with an additional radiator for the hot water supply circuit.

By installation method

Low-power liquid fuel boilers can be hung on walls pre-finished with non-flammable material. The equipment is designed to heat rooms up to 300 m². For higher capacity installations, a floor foundation is required. The equipment is secured with anchors and connected to the mains and power supply lines.

Boilers with increased productivity are installed on the floor.

Performance characteristics of fuel oil as a fuel

This type of fuel is obtained in 2 ways:

• direct distillation of oil;
• cracking - heat treatment of intermediate fractions.

Fuel oil is obtained by direct distillation of oil or heat treatment.

The product is a mixture of components:

• hydrocarbons with a molecular weight from 400 to 1000 (99%);
• petroleum resins;
• asphaltenes;
• carbenes;
• carboids;
• organic compounds, including bismuth, nickel, iron and other metals, as well as sulfur.

There are several brands of heating oil.

They are divided into 3 types:

• lungs – F5 and F12;
• medium – M40 and M40B;
• heavy - M100 and M100B.

The first type is used mainly on ship installations.

The operational characteristics of fuel oil include:

1. Specific heat of combustion – 39.4–40.7 MJ/kg.
2. Viscosity – 8–80 mm²/s.
3. Pour point – -5…+40°С.
4. Density – 0.89–1 g/cc.
5. Sulfur content – ​​0.5–3.5%.
6. Factory retail price – 20 thousand rubles/t, wholesale – 11.5.

The specific heat of combustion of fuel oil is 39.4–40.7 MJ/kg.

The cost of kWh obtained by burning fuel oil is 1.35–1.80 rubles.

For other types of fuel this figure is equal, rub.:

• main gas – 0.5;
• LNG – 2.5;
• firewood – 0.9;
• pellets – 1.33;
• coal – 1.6;
• diesel fuel – 2.8;
• electricity - 3.5.

Due to its high viscosity and pour point, fuel oil must be heated before feeding into the burner to:

• +80…+120°С – if it is under pressure in tanks or coils;
• 10°C below the flash point when kept in open containers (for different brands it is +90...+150°C).

When fuel is burned, sulfur dioxide is formed. This substance is harmful to humans - it causes a sore throat, inflammation or burn of the mucous membranes.

Preference should be given to products with minimal sulfur concentration.

Fuel oil may contain liquid. It reduces the heat of combustion and causes corrosion of metal surfaces. The water is separated by settling, which takes from 4 to 8 days.

Selection criteria: what to look for

When determining the model of liquid fuel equipment, take into account:

• area of ​​premises and height of ceilings;
• wall material and quality of thermal insulation;
• availability of space for installing a container with fuel in the boiler room or outside the building;
• the ability to install a vertical chimney of the required height;
• the need to organize hot water supply;
• ease of fuel delivery regardless of weather conditions;
• delivery and installation of the device;
• price of equipment and costs of further maintenance.

power rating

When selecting a boiler, it is necessary to take into account the area of ​​the room, where at least 1 kW of power is required for every 10 m² (the rule applies to a standard ceiling height of 2.5 m). Since the walls have different thermal insulation, a correction factor should be entered. For old buildings with poor quality materials, an index of 1.2–2.0 units is used, and for buildings with good protection and plastic windows, the coefficient is 0.6–0.9. Additionally, the ambient temperature is taken into account. When using the second circuit, a power reserve of up to 20% is introduced.

When selecting a boiler, its power is taken into account.

Economic efficiency

When calculating the parameter, take into account:

• price of equipment and additional elements;
• costs of installation and commissioning of the unit;
• cost of connecting to the electrical network;
• type and price of fuel (taking into account average consumption);
• service interval and boiler maintenance costs.

What characteristics should you pay attention to when purchasing a device?

Note! When choosing an oil-fuel boiler, the key parameters are:

1. Number of circuits. There are single-circuit and double-circuit models. The first are intended exclusively for heating rooms, the second allow you to solve the problem with hot water. Sometimes there are multi-circuit units that also provide heated floors.
2. Energy independence. Liquid fuel boilers can operate autonomously or connected to the mains. For people who live in populated areas with frequent power outages, it is better to opt for a non-volatile model.
3. Thermal power. This parameter is selected taking into account the square footage of the living space.
4. Control type. Mechanically controlled units are easy to maintain. Electronically controlled devices make it possible to program various settings and use liquid fuel economically.

List of popular manufacturers and models

There are several dozen models of liquid fuel boilers on the Russian market, suitable for installation in cottages or small industrial premises.

Self-installation of a liquid fuel boiler

The factory documentation supplied with the boilers contains a section describing the installation process.

The boiler is connected to the heating mains.

Before installation, it is necessary to level the floor or wall using solid heat-resistant material. The equipment is located in rooms with a temperature not lower than +10°C and is connected to the heating mains, fuel supply pipe, household network and chimney. Provide ventilation for the boiler room.

Free space is provided on the sides of the boiler body necessary for maintenance or repair of the installation.

Nuances of operation

The equipment is equipped with automatic control and does not require special operating conditions. It is necessary to periodically clean nozzles and dividers from deposits that negatively affect performance and stability. The owner must evaluate fuel consumption and promptly replenish the fuel supply. The tanks can be equipped with a level meter that shows the remaining diesel fuel or waste oil in the tank.

Features of fuel storage

The tank is installed in a separate room or buried in the ground next to the walls of the building. The second method is labor-intensive, but provides protection of the local area from the smell of diesel fuel. When installed above ground, plastic containers must be covered with a metal shell that protects the walls from damage and prevents fuel spills in the room. Several fire extinguishers with increased capacity (for example, OP-70) should be provided to quickly eliminate a possible fire of petroleum products.

How much fuel is required

Fuel costs depend on the power of the boiler, the area of ​​the room and the quality of heat-insulating materials. Information on fuel consumption is indicated by the manufacturer in the documentation. Under normal winter conditions, a building with an area of ​​170 m² will require up to 1.98 liters of diesel fuel per hour (using the example of Kiturami Turbo Hi FiN 13). With constant operation at maximum productivity, the consumption per day is 48 liters. In accordance with the obtained figures, a fuel tank of the required capacity is selected and timely delivery of fuel is ensured.

Fuel costs depend on the area of ​​the room.

Calculation of diesel fuel consumption by a heating boiler

To calculate the consumption of diesel fuel for heating a house, you need to know the rated power of the burner. On average, to generate 10 kW of energy, an average of 1 kg of fuel will be required, i.e. when operating in maximum mode, a 24 kW boiler will consume approximately 2.4 kg of diesel fuel per hour.

Therefore, you need to very carefully select the temperature regime for heating the coolant and, as a result, the degree of heating of an autonomous heating boiler using diesel fuel. If the equipment operates around the clock at maximum power, then at least 29 kg of diesel fuel will be required. Considering the increased cost of fuel, this is an unaffordable luxury. The following measures can be taken to reduce these costs:

• Purchasing a modular burner . It is able to accurately regulate the fuel supply level for optimal heating of the coolant;
• Selection of low temperature operating mode . This not only helps to reduce diesel fuel consumption, but will also allow you to create an effective water heated floor system;
• Buy radiators with maximum heat transfer . For them, a solar heating boiler will consume less energy to compensate for heat losses due to the passage of heat through the radiator material. It is best to install bimetallic models.

The frequency of delivery of diesel fuel for heating also plays an important role. It is recommended to install a container with enough volume for the entire heating season. In our case, provided that the system operates for 12 hours, this will be 1.2*12*90=1296 liters.

Experts advise purchasing a container with a reserve of 1500 liters. In this case, diesel fuel for the heating system can be delivered once a year before the heating season.

Safety regulations

The basic requirements are indicated by manufacturers in the technical documentation and are as follows:

1. Safety of operation depends on compliance with the manufacturer's requirements.
2. Independent repair or modernization of the burner or furnace is not allowed.
3. Electrical circuits must be grounded in accordance with the “Rules for Installing Electrical Appliances”.
4. A packet switch should be provided in the power circuit.
5. It is prohibited to operate the equipment in rooms with high humidity or dust.
6. No flammable materials should be stored in the room in which the boiler is located.
7. Coolants approved by the equipment manufacturer can be used to charge the circuit.
8. If you do not plan to operate the boiler in winter, then you should drain the water from the heating and hot water supply lines.
9. When refilling tanks, do not leave the equipment turned on.

How to reduce diesel consumption

Let's look at how to reduce diesel consumption. First of all, you should pay attention to the thermal insulation of the house. Modern materials and methods of heat conservation will reduce the number of days when it is necessary to heat and retain the heat produced.

Increasing the sections in the radiators will also increase the efficiency. Thus, the required coolant temperature is reduced, saving diesel fuel. High-quality burner adjustment using software adds 10% savings. By installing a thermostat in the room, you will avoid excessive heating of the room and automate the control of the device.

To get the maximum benefit from using a diesel boiler, you should approach its installation in a comprehensive manner. By insulating the house, designing the heating system and setting up the automation properly, you will heat the room at minimal cost.

Advantages and disadvantages

The main advantages of liquid fuel boilers:

1. Versatility. The unit can be used to heat residential or industrial buildings.
2. Independence from centralized gas supply.
3. Possibility of autonomous operation with remote parameter changes.
4. Smooth operation supported by electronics.
5. Easy maintenance and repair.
6. Increased efficiency, reaching up to 95%.
7. Low noise level during operation.
8. Possibility to turn on the heating at any time of the year.

Ease of maintenance and increased efficiency are advantages.

In addition, a number of models can operate on natural gas (after replacing the burner).

Equipment disadvantages:

• organizing a place to store fuel;
• increased cost of boilers (compared to solid fuel installations);
• increased fuel costs;
• need for power supply;
• Regular cleaning of the firebox from deposits.

The best manufacturers

Many manufacturers from Europe and Asia are engaged in the production of liquid fuel boilers. Korean heat generators are especially popular in the CIS countries, the quality and characteristics of which fully comply with European standards.

Kiturami

The Kiturami manufacturer is known for its Turbo and STSO series diesel boilers. This equipment easily competes with well-known European brands due to its low cost and rich functionality.

The only negative side of these heat generators is the high noise level. But this problem can be solved with good sound insulation.

User reviews

Andrey, 44 years old, Penza

For the production premises I purchased a Kiturami Turbo 13R double-circuit boiler. The equipment is compact, but the kit included a chimney with a large diameter. Since at the time of purchase there was no official representative office of the company in the Russian Federation, it took several weeks to resolve the issue. The boiler works stably; to start you need to press the button. I consider the disadvantage to be high fuel costs due to the constant increase in the price of diesel fuel.

Igor, 38 years old, Bryansk

The country house has a Kiturami Turbo 17R boiler with a capacity of 19.8 kW. I buy fuel myself at gas stations; there have been no problems with loss of fluidity in winter. The equipment operates noisily, but extraneous sounds do not pass through the metal door of the boiler room. The output of the hot water supply circuit was connected to the input of the electric boiler. Fuel consumption varies from 10 to 19 liters per day, on average up to 3000 liters of diesel fuel are consumed per year.

Conclusion

Liquid fuel boilers are easy to operate and are suitable for heating houses in villages not connected to a centralized gas supply. Automation of combustion processes makes it possible to maintain a given temperature, but the owner needs to supply fuel in a timely manner and carry out regular maintenance. To ensure autonomous operation, it is necessary to provide a generator driven by a diesel engine to provide power in case of emergency situations.
