Basic parameters for setting up a diesel burner. Diesel burner: how to install and configure

Service includes:

• Optimization of combustion mode settings.
• Cleaning burner elements.
• Replacement of worn burner parts.
• Cleaning or replacing filters.
• Analysis of combustion products.

Self-adjustment of the burner

After installation, setting up the diesel burner begins. Requirements for setting up the burner are indicated in its passport.

Let's consider self-configuration diesel burner Lamborghini ECO 3r. The entire setup process consists of several stages:

• Prepare tools and equipment: pressure gauge, gas analyzer, soot test, fuel injection pump and installation tool.

• Remove the burner cover.

• Install the nipple for connecting the fuel hoses so that the chamfer is on the outside, and aluminum gaskets must be used for sealing.

• Connect the hoses to the fuel pump.

• Remove the front panel of the burner from the body with the nozzle.

• Selecting the correct nozzle depends on the boiler power. The main characteristics of the nozzle: nominal flow rate, spray angle and intensity. High-quality operation of the injector should form a fuel cloud evenly distributed throughout the combustion chamber.

• To install the nozzle, the deflector is removed.

• Nozzle installation.

• Connecting the burner to the electrical network.

• It is necessary to install the ignition electrode so that the spark is at the very outlet of the fuel from the injector.

• On the solenoid valve, using the adjusting screw and pressure gauge, set required pressure from 9 to 14 bar.

• Pump fuel into the burner manually and perform a test run.

• The state of the burner can be determined by the readings of the burner control: red - emergency, yellow - warming up, green - normal.

• Install the burner on the boiler and adjust the air so that the quality of combustion products corresponds to the following values: CO up to 200 ppm; O2 from 3.5 to 5.5 ppm; CO2 from 11.5 to 13.5 ppm.

• Fine tuning is done by moving the diffuser. That is, the supply of secondary air is adjusted and the shape of the torch is adjusted, which increases the efficiency of the burner.

For the normal functioning of a diesel burner and timely detection of defects, it is necessary to carry out its prevention. If the boiler is in constant use, then inspection is carried out once every 6 months, and for seasonal use, preventive maintenance should be carried out once a year.

Setting up diesel burners

It is no coincidence that TEPLOENERGO specialists call the burner the heart of the boiler plant. And, it is this component that will determine how the entire thermal-hydraulic system in the house will behave during operation, and how safe the use of the boiler will be.

That is why, burner adjustment should be carried out exclusively by professionals and masters of their craft, and not by inexperienced self-taught people. The experience of the latter often has only a theoretical foundation (information is obtained from the Internet, from the same theorists) and is in no way supported by practical skills. But an error made in the process of setting the burner operating mode can not only damage the boiler itself, but also endanger the life and health of people in the room where it is installed...

Knowing full well that a diesel burner requires qualified maintenance, and it is also necessary to instruct the boiler owner on how to protect your unit from dust and dirt, and how to properly start the heating equipment itself, the specialists of our company TEPLOENERGO offer their services. We guarantee that the work carried out by us setting up diesel burners will allow you to enjoy the flawless operation of the equipment and not regret your choice.

Instead of trying to save money and trying to set up the burner yourself, contact the specialists of our company TEPLOENERGO straight away. Here they will take your order seriously and carry out all commissioning work efficiently, quickly and inexpensively.

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

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

Diesel burner options

Burners on diesel fuel– devices that prepare fuel for ignition in the combustion chamber. They are all divided according to the following principles:

• For fuel combustion - burners with nozzles that spray fuel into tiny particles with air, as well as burners with preliminary gasification and evaporative burners.

• By type of fuel burned: burners intended 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 operating mode of diesel burners: two-stage, single-stage, modulating.

Operating principle of the burner

The nozzle is one of the main components of the burner, through which fuel is sprayed into the burner. The operating principle 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 fuel lines thanks to a 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 removes various mechanical impurities, after which the purified fuel enters the preheating chamber. This procedure is important to reduce viscosity. The heating temperature is maintained automatically.

3).The process of burning fuel. Fuel is supplied from the heating chamber according to the injection principle: with the help of a strong flow of compressed air, a vacuum process is created in the fuel pipeline, and 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). Ignition of fuel. The process of igniting liquid fuel occurs automatically thanks to electrodes or ignition transformers.

Selecting the burner operating mode

As a rule, burners have an automatic control unit that monitors 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 at both full 100% power and only 40%.
• In a two-stage intermediate mode - here the burner power smoothly switches between 40% and 100%.
• In modulated mode – i.e. adjustment of the coolant temperature occurs due to smooth switching of the burner power within 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 diesel fuel burners, you should pay attention to the following characteristics:

· Type of fuel used;

· Thermal power;

· Amount of fuel consumed;

· Operating modes;

· Power consumption;

· Parameters and weight;

· Passport requirements from the manufacturer.

How to install the burner

The diesel burner should be installed after the boiler and chimney are installed. The burner installation process also involves 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.

The efficient and safe operation of the entire heating boiler depends on how correctly the burner is installed. Therefore, for proper installation of the burner, you should adhere to the rules for installation work. It is better to seek the services of professional craftsmen.

Burner setup + servicing

Setting up a diesel burner should be done by the specialists who installed it. They are the ones who must configure it for a specific type of fuel. However, burners also require attention during operation. Their components experience strong temperature changes, clogging of fuel paths (from poor quality diesel fuel), which subsequently leads to equipment failure. Therefore, 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:

1. Optimization of combustion mode settings;
2. Cleaning burner components;
3. Replacement of worn burner parts;
4. Cleaning or replacing filters;
5. Analysis of processed products.

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

Once the burner is installed, it needs to be adjusted. Everything regarding the burner settings, all requirements and rules, you can find in its passport.

So, using the Lamborghini ECO3r diesel burner as an example, we’ll 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 measurement test, fuel pump, installation tool).

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

4).Connect the hoses to the fuel pump.

5).Now we disconnect the front panel from the body with the nozzle.

6).Select the nozzle taking into account the power of the boiler. Its main characteristics: angle, spray intensity, nominal flow rate. At quality work the injector should form a “fuel cloud”, which is evenly distributed throughout the combustion chamber.

7).Remove the deflector to install the nozzle.

8).Install the nozzle.

9).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 injector.

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

12).Finally, the time has come to pump fuel into the burner, first we do a test run.

P The burner display shows the state of the burner. In case of an accident – ​​red, when warming up – yellow, in normal condition – green.

13).When installing the burner on the boiler, the air should be adjusted so that the quality of the combustion products matches the following values: CO up to 200ppm; 02 from 3.5 ppm to 5.5 ppm; CO2 from 11.5 ppm to 13.5 ppm.

It consists of preparing the mixture and burning it. Exists a large number of various burners. Some are used in solid fuel boilers, others work with liquid fuel. It is the latter that we will talk about. Let's figure out what a diesel burner is, where it is used and what its key features are.

General information

A diesel burner is installed in heating equipment that uses liquid fuel. In particular, we're talking about about heavy oils, for example, waste oil or diesel. Typically, such burners work in tandem with floor-standing equipment for household and industrial purposes. Often this type of heating is installed where there is no gas main. This is due to the fact that it is much more expensive natural gas, which, in fact, limits the scope of its application and prevalence. In general, diesel boilers are no worse than conventional gas boilers. They have high efficiency, economical, good heat dissipation and can be fully automated. In order for the burner to operate efficiently, constant pressure must be maintained in the system. Therefore, a compressor is installed, and for it it is important to provide a stable source of energy, which is quite difficult for a number of reasons.

Diesel burner for a boiler: operating principle

Let's take a quick look at how the burner works. From the tank, diesel is supplied to the burner. To ensure the supply of fuel, a special pump is used, which is equipped with a return line, which is necessary for the circulation of fuel between the pump and the tank. In this case, the burner uses as much fuel as it needs, and the remainder is returned back to the tank. But before the diesel reaches it, it must pass through the filter and. At the first stage, mechanical elements are cleaned, and at the second, the fuel is heated to the optimal temperature.

Atomization in the combustion chamber is carried out using a nozzle. At the same time, air is forced through the burner pipe. The shape of the torch is controlled using special blades that create an air vortex. Electrodes are installed directly in front of the nozzle to ensure the mixture ignites. This is how a diesel burner for a boiler works. The entire process is controlled using automation devices.

Briefly about the classification of burners

Currently, manufacturers offer consumers three types of burners. They all have design features and differ in cost. Therefore, all burners can be divided into the following groups:

• single-stage - operate in 100% power mode without the possibility of adjustment;
• two-stage - you can set the operating mode to 100 or 50%;
• modulated - there are wide possibilities for adjusting power, usually in the range from 10 to 100%.

The last option is the most preferable. This is due to the fact that it is possible to smoothly regulate the temperature of the coolant. But at the same time, such devices are quite expensive and complex, so their repairs must be carried out by professionals. However, you no longer need to adjust diesel burners. And this is very important.

Setting up diesel burners

Often the adjustment is carried out by specialists, but if desired, adjustment work can be done with your own hands. If a single-stage burner is used, the work is done quite quickly and simply. All manipulations boil down to regulating the supply of air and fuel to ensure normal combustion. In this case, the mixture must be enriched. The quality of the flame is determined by eye. If the settings are completed, then you can use a gas analyzer, which will determine the content of CO and CO 2 in the smoke. If the burner is “standing”, then first of all it is necessary to check the contacts and operability of the components as a whole and each separately. But setting up diesel burners with the ability to adjust power (modulated) is quite difficult, and this will require special equipment.

How to start a new burner

If your old diesel burner is faulty and cannot be repaired, then a complete replacement will be required. This kind of work can be done with your own hands. To do this, you need to remove the old burner and check the integrity and quality of the nozzle. If it is clogged, it needs to be cleaned compressed air or a thin metal object. Next, the preliminary position of the electrodes is checked and the functionality is checked manually. During operation, there should be no unnecessary noise (friction, whistling), which will indicate normal operation. Don't forget to tighten the cotter pin on the impeller. On next stage it is necessary to inspect the boiler furnace. The burner is mounted on the door. All work must be performed in sequential order according to the instructions. Do not forget that when starting the burner on diesel fuel for the first time, you must remove the fuel hose and run it dry. Well, now let's move on.

Making a burner with your own hands

Typically, homemade burners are less economical than those made by professionals, so be prepared to increase fuel consumption by 5-10%. Before taking into account, sketch out a sketch and be sure to remember the dimensions of the firebox and vent. If you make a one-stage diesel burner with your own hands, then first a monoblock design with supercharging is made. It is advisable to purchase a package of mounting accessories with a housing and a cover for the burner. In this case, be sure to take into account the compatibility of the burner with the generator.

Making a burner with a compressor is more complex, but effective. An ordinary Chinese-made spray gun is suitable as a compressor. This way, fuel will be consumed economically, the quality of the mixture will be at the proper level, and you will have the opportunity to adjust the power of the equipment. If a DIY diesel burner is made with high quality and reliability, then it will not pose any danger to others.

Diesel burner repair

If you decide to spend renovation work with your own hands, then stock up on rags, since this is not the most clean work. First, make sure that oxygen is passing through the injector nozzle. It often happens that it gets clogged and the mixture turns out not enriched, as a result of which the quality of the torch decreases. If the injectors are clean, look at the filter. If it needs to be replaced, do so. In addition, if used oil is used, the channel may become contaminated. It must first be blown out with a hose. In principle, this is what repairs of diesel burners are limited to. Sometimes it makes sense to check the condition of the electrodes. If noticed mechanical damage or wear, it is better to change the part or assembly.

A few important details

Many experts advise paying attention to burners when purchasing them. In particular, their power matters, which must exceed the combustion power of the boiler. In addition, it makes sense to pay attention to the type of adjustment. For household use one thing is enough two-stage burners. But for a small boiler room, modulated options are better. Some burners cannot operate on multiple fuel types. That is why it is advisable to take care of reserve fuel when purchasing. Therefore, the burner should work equally well on diesel and, for example, good choice there will be a Lamborghini diesel burner, which is famous not only for its high reliability, but also for the ability to use a wide variety of fuels.

Conclusion

So we talked to you about the features of diesel burners. As you can see, if necessary, you can make them yourself. If necessary, you will always find a large assortment of equipment that interests you on sale. Diesel burner "Lamborghini" ECO series allows you not only to efficiently heat the room, but also to take care of environment.
