How does a gas boiler work?

As an efficient and environmentally friendly heating equipment, gas boilers are widely used in various fields. Its working principle can be divided into the following steps:

Fuel injection: The fuel (natural gas, coal gas, etc.) of the gas boiler enters the burner through the pipeline. Inside the burner, the fuel is atomized into tiny particles. This is to increase the contact area between the fuel and the air and improve the combustion efficiency.
Combustion process: In the burner, the atomized fuel is mixed with air and then ignited under the action of the ignition device. During the combustion process of fuel, a large amount of heat is released, which is transferred to the water in the boiler.
Heat transfer: The water in the boiler begins to heat up after receiving heat, gradually producing steam or hot water. In this process, heat is transferred from the burner to the water, which is heated and boils to produce steam, which can be used to drive a steam turbine or heat heating pipes.
Flue gas emission: The flue gas produced by combustion is discharged from the boiler through the flue. In the flue, part of the heat is recovered and utilized, improving overall energy efficiency.
Automatic control: Gas boilers are usually equipped with an automatic control system, which can control the temperature of the boiler by adjusting the flame size of the burner. When the temperature reaches the preset value, the control system will automatically turn off or reduce the burner flame to save energy.

In general, the working principle of a gas boiler is to generate heat by burning fuel to heat the water in the boiler, producing steam or hot water. This steam or hot water is then used to drive the steam turbine or heat the heating pipes to achieve energy conversion and heating. use. At the same time, during the operation of gas boilers, attention should be paid to safety and environmental issues, such as regularly checking the sealing of gas pipelines and properly arranging ventilation in the boiler room.
