What is the definition of a diesel burner?

A diesel burner is a burner that uses diesel fuel as its fuel and can be used in places that do not have access to city gas.

diesel burner performance:

Diesel burners, when the engine starts, the ventilation fan starts working. The ventilation fan in these burners is of centrifugal type.

In diesel burners, in addition to moving the ventilation fan, the electric motor is also responsible for turning the diesel pump.

The pump for diesel burners is a high pressure gear type.

In this way, the operation of the diesel pump and air are mixed together and ready for combustion.

The pump for diesel burners is a high pressure gear type.

In this way, the operation of the diesel pump and air are mixed together and ready for combustion.

Diesel burner components:

diesel burner fan
Electric motor (its function is to turn the axis of the diesel fan)
Damper or air regulation valve (controls the air inlet damper to the burner)
Air rotation plate (this plate rotates the exhaust air for better mixing with fuel and The screen used in it is equipped with turbine blades)

diesel burner working steps Forced evacuation stage:

At this stage, the relevant relay is connected to the engine and the engine starts working.

As a result, the fan starts working at the same time as the engine is turned on.

And it sucks the surrounding air into the diesel burner and transfers it to the boiler or combustion chamber.

On the other hand, the diesel pump is activated and delivers diesel to the back of the solenoid valve.

The duration of this stage is different in different relays and torches and it is about 30 to 90. As the air enters the combustion chamber by the fan, fuel vapor and harmful gases are left from the previous combustion through the chimney and the combustion chamber is filled with healthy air, this work is called riveting.

Confidence stage:

In the assurance phase, the relay also commands the solenoid valve and the ignition in addition to the engine.

Therefore, the solenoid valve starts working and allows fuel to pass; On the other hand, the igniter is also lit and a flame is formed at the tip of the diesel burner by providing three ignition factors.

If a flame is formed at this stage, the photocell enters the circuit and sends the message of the existence of the flame to the relay, and the diesel burner enters the next stage of its work.

Permanent work stage:

At this stage, upon receiving the photocell message based on the existence of the electric flame, the relay keeps the motor and solenoid valve connected and removes the spark transformer from the circuit.

In this case, the flame is stable and the diesel burner continues to work until receiving the command from the thermostat on the boiler.

By operating the thermostat, the input power to relay pin 9 is cut off and the diesel burner is turned off and goes to rest.

Application of diesel burner:

This burner is used for high efficiencies such as the following:

power plants
Refineries
Cement industries
Petrochemical units
Dairy products factories
For the use of small industries and steam boilers
For heating systems and hot water supply

Technical specifications of the diesel burner:

The technical specifications of the diesel burner based on the model are as follows:

diesel burner warranty and effective factors during its lifetime:

This product has 12 months warranty and 10 years after sales service.

The factors affecting the life time of a diesel burner are:

For better performance, the following are significant.

Adjust the electrodes.
Adjust the static pressure.
Use the right fuel.
Adjust the air-fuel ratio.
