Setting up a diesel burner. Diesel burner for a boiler: principle of operation

18.10.2019

With the help of liquid fuel boilers, it is possible to efficiently heat industrial and domestic premises. As a fuel, you can use: kerosene, waste oil from various industries, diesel fuel, etc. In our article, we will consider the principle of operation of burners for diesel fuel, as well as the types and settings of this device.

Principle of operation

The nozzle is a type of burner. She sprays fuel. Consider its principle of operation, which consists of several parts:

Fuel preparation. Any type of fuel becomes contaminated over time, and in order to prevent various impurities from entering the burner, a fuel filter is installed before fuel is supplied to the burner. The filter removes impurities from the fuel, and then the fuel enters the preheating chamber to reduce the viscosity. The fuel is heated at a certain temperature, which is in automatic mode;
Fuel supply. With the help of a fuel pump, fuel is supplied from the fuel tank through the fuel lines;
Ignition of fuel occurs with the help of an ignition transformer in automatic mode or electrodes;
Fuel combustion. According to the injection principle, fuel is supplied from the heating chamber. Thus, the fuel and the air flow are mixed and fed to the nozzle. And in it the process of spraying the liquid into small drops takes place, which in turn are distributed evenly over the volume of the combustion chamber. Secondary air is supplied by a fan, which is equipped with a damper for regulation.

Types of burners for diesel fuel

The burner is a device that prepares the fuel, as well as its ignition in the combustion chamber. Consider the types of burners for diesel fuel.

Burners can be divided according to the principle of fuel combustion:

Evaporative burners.
Nozzles that atomize fuel into fine particles mixed with air.
Burners with pre-gasification.

More burners are divided according to the type of fuel burned:

Combined burners for liquid and gaseous fuels.
Burners for liquid fuel.

Burners can be divided according to the mode of operation:

Modulating burners.
Double stage burners.
Single stage burners.

Burner device

Before buying a burner for diesel fuel, you need to pay attention to the following nuances: thermal power, fuel burned, operating mode, fuel consumption, dimensions and weight, passport requirements and power consumption.

After the installation of the heating boiler and chimney, you can install the burner. To install the burner, it is necessary to install additional equipment: a filter, a pump, a fuel tank with a float, a compressor, a piping system, a fan, a burner with an ignition system and a control unit. But there are burners that include everything necessary equipment and therefore do not require the installation of any additional devices.

The installation of the burner affects the efficiency and safety of the boiler. It must be installed taking into account all requirements. It is not recommended to install the burner on your own, so it is better to seek help from a specialist.

How to choose fuel for the burner

The passport of any burner indicates the requirements for fuel. Therefore, if you follow all the rules, you can increase the life of the burner.

How to set up your own burner

After installing the burner, you need to proceed to its configuration. In the passport of any burner, the requirements for setting it up are indicated. Consider the burner setting, which consists of several stages:

First of all, you need to prepare the necessary equipment and tools: a test for measuring soot, a pressure gauge, a fuel injection pump, a gas analyzer, and an installation tool.
Next, you need to remove the burner cover.
To connect the fuel hoses, you need to install the nipple so that the chamfer is outside. It is necessary to use aluminum gaskets for high-quality sealing.
Next, you can connect the hoses to the pump.
The front panel of the burner must be detached from the body with the nozzle.
To select the correct nozzle, you need to know the power of the boiler. Consider the main characteristics of the nozzle: the intensity and angle of spray, as well as the nominal flow rate. If the nozzle works efficiently, then a fuel cloud should form, which will be evenly sprayed throughout the combustion chamber.
To install the nozzle, you need to remove the deflector.
Then you can install the nozzle.
Next, you need to connect the burner to the mains.
The ignition electrode must be installed in such a way that the spark is located at the very exit of the fuel from the nozzle.
It is necessary to set the required pressure on the solenoid valve. This can be done using a pressure gauge and an adjusting screw. The pressure should be 9-14 bar.
Now you can pump fuel into the burner and make a test run.
According to the readings of the combustion machine, you can find out about the state of the burner. The norm should be green color if shown yellow, then this indicates warming up, and if it is red, then it indicates an accident.
Now you can install the burner on the boiler and adjust the air. The quality of combustion products must correspond to the following values: CO up to 200 ppm; O2 3.5-5.5 ppm; CO2 11.5-13.5 ppm.
By moving the diffuser fine-tuning is performed. In this way, the secondary air supply is regulated and the shape of the flame is adjusted, which in turn increases the quality and efficiency of the burner.

In order to find and eliminate any malfunctions of the burner in time, it is necessary to periodically prevent it. If you use the heating boiler regularly, then prevention should be carried out every six months. If the boiler is used only for seasonal use, then it will be enough to carry out diagnostics once a year.

Water heating

physical characteristics

Choosing one or the other heating equipment depends on the availability of the most affordable source of energy. When there is no central gas supply, but there is access to a large amount of processed hydrocarbon raw materials - fuel oil, oil, diesel fuel, then a diesel burner as part of heating equipment will be the most profitable option. The cost and energy efficiency of the boiler plant will depend on which design you choose.

Diesel burners

Diesel burners use liquid combustible substances as fuel - fuel oil, waste oil, diesel fuel. But, as a rule, a mixture of these materials is used in practice - this is how it is possible to achieve the most beneficial economic effect.

When the first diesel burners for boilers began to operate, a number of serious problems arose. The first of these is the clogging of the chimney and the loss of draft due to the release a large number carbon monoxide, soot and soot during the combustion of "combined" fuel. The second is the "freezing" of liquid fuel, a situation where the mixture became too viscous and it was impossible to ignite.

The device of diesel burners

To solve the first problem, an air fan is included in the diesel burner, which creates excess pressure in the system, which ensures forced air circulation and constant draft. To prevent the "freezing" of the fuel, a heating chamber is built into the design of the heating equipment, which heats the mixture to the temperature required for spraying by nozzles.

In view of the heterogeneity of the fuel, the temperature of its combustion can be different. Therefore, before entering the combustion chamber, the diesel burner disperses the mixture with the help of a nozzle. Fine atomization of fuel accelerates and stabilizes the combustion process.

Thus, a diesel burner consists of at least three elements - a nozzle, a heating device and an air fan. It is also possible to add fuel lines and a filter system to the structure, as well as voltage rectifiers and uninterruptible power supplies to ensure autonomous operation of the boiler.

Principle of operation

The operation of a diesel burner can be conditionally divided into two stages - fuel preparation and combustion itself. At the first stage, diesel burners for boilers, using a fuel pump, "pass" the combustible mixture through the filter system and "pump" it into the heating chamber. Here the fuel is heated to optimal temperature and then fed to the injectors.

It is worth saying that the design of the fuel pumps includes a return line, which causes the mixture to continuously circulate between the tank and the combustion chamber - the nozzle takes only the amount that is necessary to maintain the flame.

The second stage begins with the creation of an air vortex by the fan inside the combustion chamber. At the same time, the nozzle sprays the composition, and the electrodes ignite it. The air vortex maintains a constant pressure in the system and determines the shape of the flame. Thanks to this, the diesel burner operates in a given temperature regime.

Selecting the optimal burner

The use of oil burners gives greater freedom for implementation various projects heating systems. And in order to achieve the creation of the most profitable option, it is necessary to determine the following parameters for the heating boiler you already have:

The maximum allowable power of the boiler, the so-called furnace power.
Combustion chamber dimensions.
Manufacturer's requirements for the burner.

The above parameters can be found in the data sheet or on the manufacturer's website. The diesel burner you choose must comply with the clarified parameters. But for optimal operation, it is better that its power slightly exceeds the furnace power of the boiler. This will allow you to have an optimal range of flame temperature control.

Another important parameter is the type of fuel used. Here you need to focus on the sources available to you. It is not superfluous to think about its alternative version.

Varieties of burners

The last thing to consider before making a purchase is the design, which determines whether the diesel burner will support the ability to regulate the temperature of the flame, work offline, as well as the cost of the device and its life. Currently, experts distinguish four categories of equipment - single-stage, two-stage, smoothly-staged and modulated.

As a rule, the presented types of burners are interchangeable, that is, if a single-stage design fits into your boiler, then you can easily install a modulated one. Each type of device has its own advantages and disadvantages, the knowledge of which will help you create the optimal heating system for your building.

One- and two-stage installations

A single-stage burner is a classic design installed in a diesel boiler. Heating through such an installation is not the most convenient, but the most reliable. The thing is that a single-stage system operates in only one mode - at 100% power.

To regulate the heating medium heating temperature, it is necessary to periodically turn on/off the burner. This leads to the main disadvantage - high fuel consumption. The main advantages of a single-stage design are:

Simple design, which determines its durability and maintainability.
Low cost and low maintenance costs.
Less dependence on automation systems.

The two-stage burner operates in two modes. These can be modes of 30/100% power, or 40/100%. The principle of operation of such structures is simple - at 100% heating of the coolant, the automation gives a signal to reduce the intensity of the flame to 30% or 40%. After the boiler cools down to a certain temperature, the burner starts to function normally.

The main advantages of such burners are efficiency and autonomy. Disadvantages - higher cost and high maintenance costs, lower reliability and durability due to the presence of automation. A typical representative of this category of devices is the Lamborghini diesel burner.

Smoothly stepped and modulating equipment

In sliding-stage installations, in contrast to two-stage ones, the flame temperature is controlled within a user-defined range. The increase in work power occurs gradually as the boiler cools down, and not abruptly. In this regard, fuel consumption is reduced and maintenance costs are reduced. The disadvantage of the systems is the high cost and high requirements for the power grid - it must be stable.

Modular designs are the most economical and convenient options available for installation in a diesel boiler. Heating is regulated by microprocessor technology, which measures the air temperature in the room, the state of the combustible mixture and gives a signal to increase or decrease the power of the flame. Significant disadvantages are high price, complex design, high costs for content.

Hardware setup

The installation and adjustment of the diesel burner must be carried out exclusively by specialists. You should not do this on your own. The thing is that the master adjusts the nozzle for the diesel burner - how it will spray the combustible mixture.

If the amount of sprayed mixture is incorrectly adjusted, it will be excessive, which will lead to its detonation and explosion of heating equipment. Otherwise, the amount of fuel supplied may not be sufficient to maintain the set temperature.

Today, the most popular is the Lamborghini diesel burner from Italy. In second place are the companies Elco, Baltur, Ferroli. When choosing the optimal equipment, it is necessary to pay attention to the power, design, the presence of a fuel heater, and only then to its cost. Only in this case you will not be disappointed in the purchase.

Liquid fuel boilers are devices whose operation is highly efficient. They easily cope with heating both domestic and industrial premises. have their own design feature- the presence of a diesel burner. It is a diesel burner that ensures the operation of such equipment, keeping our house warm and cozy!

Liquid fuel used different types: diesel fuel, kerosene, recycled oil, etc.

Diesel burner options

Diesel burners are devices that prepare fuel for ignition in a combustion chamber. All of them are divided according to the following principles:

For fuel combustion - burners with nozzles that atomize the fuel into the smallest particles with air, as well as burners with pre-gasification, and evaporative burners.

By type of combustible fuel: burners designed only for liquid fuel, and combined burners, can be used for two types of fuel (liquid and gaseous, i.e. gas-diesel burners).

According to the mode of operation of diesel burners: two-stage, one-stage, modulated.

How the burner works

The nozzle is one of the main components of the burner, with the help of which fuel is sprayed into. The principle of operation of such a nozzle for diesel burners occurs in several stages:

1). Fuel supply. The fuel is stored inside the fuel tank. It is transported through the fuel lines thanks to the fuel pump.

2).Fuel filtration. Any type of fuel can become contaminated. Based on this, before the fuel enters the burner, it is cleaned using a fuel filter. This filter is necessary, it cleans from various mechanical impurities, after which the purified fuel enters the preheating chamber. This procedure is important to reduce viscosity. The temperature for heating is maintained automatically.

3). The process of burning fuel. Fuel is supplied from the heating chamber according to the principle of injection: using a strong flow compressed air a rarefaction process is created in the fuel pipeline, fuel is sucked in. As a result, the air flow and fuel, mixing, enter the nozzle. Inside the nozzle, the liquid is sprayed into tiny droplets, filling the entire volume of the combustion chamber. A strong, compressed air flow is created by the compressor. Secondary air is supplied by a fan equipped with a special damper for adjustment.

4). Fuel ignition. The process of ignition of liquid fuel occurs automatically due to ignition electrodes or transformers.

Selecting the burner operating mode

As a rule, burners have an automatic control unit that controls the safety of the equipment and its temperature.

The burner can operate in the following modes:

In single-stage mode, i.e. always at 100% power. In this case, the temperature of the coolant is regulated by constantly turning the burner on and off.
In two-stage mode, the burner operates both at full 100% power, and only at 40%.
In two-stage intermediate mode - here the burner power smoothly switches between 40% and 100%.
In modulated mode - i.e. the coolant temperature is adjusted due to the smooth switching of the burner power in the range from 10% to 100% of its power.

As for the choice of fuel, it has its own requirements, which you can find directly in the burner passport.

How to choose a burner

When choosing burners for diesel fuel, you should pay attention to the following characteristics:

The type of fuel used;

· Thermal power;

The amount of fuel consumed;

· Modes of operation;

· Power consumption;

· Parameters and weight;

· Passport requirements from the manufacturer.

How to install the burner

The diesel burner should be mounted after the boiler and chimney have been installed. The burner installation process also includes the installation of additional equipment, namely, a fuel tank with a float, a filter, a pump, a piping system, a compressor, a fan and a burner with control modes and an ignition system.

Some diesel burners have all the necessary elements and therefore such burners do not require the installation of additional equipment.

How correctly the burner is installed determines whether the operation of the entire heating boiler will be efficient and safe. Therefore, for a well-executed installation of the burner, you should follow the rules for installation work. And it is more desirable to seek the services of professional craftsmen.

Burner adjustment + service

The adjustment of the diesel burner must be carried out by the specialists who installed it. It is they who must adjust it to a specific type of fuel. However, burners also require attention during operation. Their components experience strong temperature fluctuations, clogging of fuel paths (due to poor quality diesel fuel), which further leads to equipment damage. Therefore, in order to extend the service life, as well as to avoid breakdowns of diesel burners, preventive maintenance should be done from time to time.

Service includes:

Optimization of combustion mode settings;
Cleaning the components of the burner;
Replacement of worn parts of the burner;
Cleaning or replacing filters;
Analysis of processed products.

So, now let's figure out how to set up a diesel burner:

After the burner is installed, it must be adjusted. Everything related to the settings of the burner, all the requirements and rules, you can find in her passport.

So, using the example of the Lamborghini ECO3r diesel burner, we will tell you how to set it up yourself. This setup consists of several steps:

1). Preparation of tools and equipment (pressure gauge, gas analyzer, soot test, fuel pump, installation tool).

3). Then we connect the nipple for connecting fuel hoses, taking into account that the chamfer is outside. Important! For better tightness it is necessary to use aluminum gaskets.

4). Connect the hoses to the fuel pump.

5).Now detach the front panel from the housing with the nozzle.

6). We select the nozzle taking into account the power of the boiler. Its main characteristics: angle, spray intensity, nominal flow. With the high-quality operation of the nozzle, a “fuel cloud” should form, which is evenly distributed over the combustion chamber.

7). Remove the deflector to install the nozzle.

8). Install the nozzle.

9). We connect the burner to the mains.

10). Now we install the ignition electrode so that the spark is close to the fuel outlet from the nozzle.

11). We set the required pressure from 9 bar to 14 bar on the solenoid valve, using a pressure gauge and adjustment screw.

12). Finally, it's time to pump fuel into the burner, first we make a test run.

P The display of the burner control shows the state of the burner. In case of an accident - red, during warming up - yellow, in normal - green.

13). When installing the burner on the boiler, adjust the air in such a way that the quality of the combustion products matches the following values: CO up to 200ppm; 02 3.5ppm to 5.5ppm; CO2 from 11.5ppm to 13.5ppm.

This service is available from 3500 rubles.

A necessary component of any boiler is a burner. It is on how the burner functions that the operation of the unit as a whole depends. Burners are:

gas;
diesel (liquid fuel);
pellet.

The main function for any type of burner is to burn the right amount of fuel. Burner failure threatens to reduce the life of the entire system. Therefore, it is important to do it correctly. Modern burners of the modern type have automatic systems. But, despite this, they tend to break. Repair and maintenance of burners is not recommended to be carried out independently. For such purposes, there are qualified employees of service centers.

Proper burner operation

For the smooth functioning of the burner, it is necessary to control the correct operation of the burner. There are a number of conditions for this:

It is necessary to ensure the appropriate level of voltage supply in the network, without drops. This is easy to do using voltage stabilizers, which will help the mechanism work smoothly and guarantee the safety of the owners;
It is recommended to install a relay to control the gas pressure in the gas pipeline;
Problems with the operation of the mechanism may arise due to a large accumulation of dust. To eliminate it, it is necessary to carry out wet cleaning in the room, as well as to clean the burner at least 2 times a year.

Failure can be caused by insufficient air flow in the room. This contributes to the fouling of the burner and the boiler. Contact our service center should be if you notice such manifestations: bad smell, unusual increased noise, increased fuel consumption.
