Using liquid fuel boilers, you can effectively heat production and household premises. The fuel you can use is: kerosene, waste oil from various industries, diesel fuel, etc. In our article we will look at the operating principle of diesel fuel burners, as well as the types and settings of this device.

Principle of operation

A nozzle is a type of burner. She sprays fuel. Let's look at its operating principle, 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 supplying fuel to the burner. The filter removes impurities from the fuel, and then the fuel enters a preheating chamber to reduce viscosity. The fuel is heated to a certain temperature, which is in automatic mode;
• Fuel supply. Using a fuel pump, fuel is supplied from the fuel tank through fuel lines;
• Fuel is ignited using an ignition transformer in automatic mode or electrodes;
• Fuel combustion. Using the injection principle, fuel is supplied from the heating chamber. Thus, the fuel and air flow are mixed and supplied to the nozzle. And in it there is a process of spraying liquid into small drops, which in turn are distributed evenly throughout 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

A burner is a device that prepares fuel and ignites it in the combustion chamber. Let's consider the types of burners for diesel fuel.

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

1. Evaporative burners.
2. Nozzles that spray fuel into small particles mixed with air.
3. Burners with pre-gasification.

Burners are also divided according to the type of fuel burned:

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

Burners can be divided by operating mode:

1. Modulating burners.
2. Two-stage burners.
3. Single stage burners.

Burner device

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

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

How to choose fuel for the burner

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

How to set up the burner yourself

After installing the burner, you need to move on to setting it up. The passport of any burner indicates the requirements for setting it up. Let's look at setting up the burner, which consists of several stages:

1. 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.
2. Next you need to remove the burner cover.
3. To connect the fuel hoses, you need to install the nipple so that the chamfer is on the outside. It is necessary to use aluminum gaskets for high-quality sealing.
4. Next, you can connect the hoses to the pump.
5. The front panel of the burner must be disconnected from the body with the nozzle.
6. To choose the right nozzle you need to know the power of the boiler. Let's consider the main characteristics of the nozzle: intensity and spray angle, as well as nominal flow rate. If the injector works well, then a fuel cloud should form, which will be evenly sprayed throughout the combustion chamber.
7. To install the nozzle you need to remove the deflector.
8. Then you can install the nozzle.
9. Next, you need to connect the burner to the electrical network.
10. The ignition electrode must be installed so that the spark is located at the very outlet of the fuel from the injector.
11. You need 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.
12. Now you can pump fuel into the burner and do a test run.
13. Based on the readings of the burner control unit, you can find out about the condition of the burner. Should be normal green color, if shown yellow, then this indicates warming up, and if it is red, then it indicates an accident.
14. 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.
15. By moving the diffuser, you can fine tuning. In this way, the supply of secondary air is regulated and the shape of the torch is adjusted, which in turn increases the quality and efficiency of the burner.

In order to find and eliminate any problems with the burner in a timely manner, it is necessary to carry out periodic preventative maintenance. If you use your heating boiler regularly, then maintenance 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.

The choice of one heating equipment or another depends on the availability of the most accessible energy source. 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 the most profitable option would be a diesel burner as part of the heating equipment. The cost-effectiveness and energy efficiency of the boiler installation will depend on which design you choose.

Diesel burners

Diesel burners use liquid flammable substances as fuel - fuel oil, waste oil, diesel fuel. But, as a rule, in practice a mixture of these materials is used - this is how the most profitable economic effect can be achieved.

When the first diesel burners for boilers began to be used, a number of serious problems arose. The first of them is clogging of the chimney and loss of draft due to the release of large amounts of carbon monoxide, soot and soot when burning “combined” fuel. The second is the “solidification” of liquid fuel, a situation where the mixture becomes too viscous and cannot be ignited.

Design of diesel burners

To solve the first problem, an air fan is included in the diesel burner, which creates overpressure what is provided forced circulation air and constant draft. To prevent the fuel from “solidifying,” a heating chamber is built into the design of the heating equipment, which heats the mixture to the temperature required for spraying by nozzles.

Due to the heterogeneity of the fuel, its combustion temperature may be different. Therefore, before entering the combustion chamber, the diesel burner disperses the mixture using 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. The design can also include fuel lines and a filter system, as well as voltage rectifiers and sources uninterruptible power supply to provide battery life boiler

Principle of operation

The operation of a diesel burner can be roughly 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 supplied to the injectors.

It is worth saying that the design of fuel pumps includes a return line, which forces 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 fan creating an air vortex inside the combustion chamber. At the same time, the nozzle sprays the composition, and the electrodes ignite it. The air vortex maintains constant pressure in the system and determines the shape of the flame. Thanks to this, the diesel burner operates at the specified temperature.

Choosing the optimal burner

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

1. The maximum permissible power of the boiler, the so-called combustion power.
2. Combustion chamber dimensions.
3. Manufacturer's requirements for the burner.

The above parameters can be found from the data sheet or on the manufacturer’s website. The diesel burner you choose must comply with the specified parameters. But for optimal performance It is better that its power slightly exceeds the combustion power of the boiler. This will allow you to have an optimal range of flame temperature control.

To others important parameter is the type of fuel used. Here you need to focus on the sources available to you. It would not be amiss to think about an alternative version.

Types of burners

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

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

One- and two-stage installations

The 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 the single-stage system operates in only one mode - at 100% power.

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

1. Simple design, which ensures its durability and maintainability.
2. Low cost and low maintenance costs.
3. 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 operating principle of such structures is simple - when the coolant is heated to 100%, the automation gives a signal to reduce the flame intensity to 30% or 40%. After the boiler has cooled to a certain temperature, the burner begins to function normally.

The main advantages of such burners are efficiency and autonomy. Disadvantages - higher cost and higher maintenance costs, less 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 smooth-step installations, unlike two-stage ones, the flame temperature is controlled within a user-defined range. The increase in operating power occurs gradually as the boiler cools, and not abruptly. In this regard, fuel consumption is reduced and maintenance costs are reduced. The disadvantages of the systems are 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. The heating is regulated by microprocessor technology, which measures the air temperature in the room, the state of the combustible mixture and gives a signal when the flame power increases or decreases. Significant disadvantages are the high price, complex design, high costs for content.

Equipment setup

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

If adjusted incorrectly, the amount of sprayed mixture will be excessive, which will lead to its detonation and explosion of the heating equipment. Otherwise, the amount of fuel supplied may be insufficient to maintain the specified 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, you need to pay attention to the power, design, presence of a fuel heater, and only then to its cost. Only in this case you will not be disappointed in the purchase.
