What is a gas boiler burner

The gas boiler burner is one of the core components of the gas boiler. Its main function is to mix gas and air in a certain proportion and ignite it to produce a stable flame, thereby providing heat for the boiler. It is a key component for the efficient and safe operation of gas boilers.

Basic components of gas boiler burners

Gas supply system

Includes gas pipelines, gas valves, pressure regulators, etc., which are used to control the flow and pressure of gas.

Air supply system

Includes fans, dampers, etc., which are used to provide the air required for combustion and adjust the mixing ratio of air and gas.

Mixing device

Fully mix the gas and air to ensure combustion efficiency.

Ignition system

Used to ignite the mixed gas, common methods include electric spark ignition, hot surface ignition, etc.

Combustion chamber

The mixed gas burns here to produce a high-temperature flame to provide heat for the boiler.

Flame monitoring system

Monitor the flame state to ensure stable combustion. If the flame goes out, the system will automatically cut off the gas supply to prevent gas leakage.

Control system

Used to adjust the flow of gas and air and control the combustion process, usually including sensors, controllers, etc.

Casing and bracket

Protect internal components and provide support.

Working principle of gas boiler burner

Gas enters the burner through the gas supply system.

Air enters the burner through the fan or natural ventilation.

Gas and air are mixed in proportion in the mixing device.

The ignition system ignites the mixed gas to form a flame.

The flame burns in the combustion chamber, releasing heat to heat the water or steam in the boiler.

The control system monitors the combustion state in real time, adjusts the flow of gas and air, and ensures efficient and safe operation.

Types of gas boiler burners

🔘Classification by combustion method

Premix burner: gas and air are fully mixed before combustion, with high combustion efficiency and low pollutant emissions.

Diffusion burner: gas and air are mixed during the combustion process, with a simple structure but low efficiency.

🔘Classification by adjustment method

Single-stage fire burner: only two states of on and off, suitable for small boilers.

Two-stage fire burner: there are two states of high fire and low fire, suitable for medium-sized boilers.

Proportional regulation burner: can continuously adjust the flow of gas and air according to load demand, suitable for large boilers.

🔘Classification by fuel type

Natural gas burner: uses natural gas as fuel.

Liquid petroleum gas (LPG) burner: uses liquefied petroleum gas as fuel.

Artificial gas burner: uses artificial gas as fuel.

Advantages of gas boiler burner

🔘High efficiency and energy saving

High combustion efficiency, high heat utilization rate, and significant energy saving effect.

🔘Environmental protection and low emissions

Full combustion, low emissions of pollutants (such as CO, NOx).

🔘High degree of automation

Equipped with advanced control system, it can realize automatic ignition, adjustment and monitoring.

🔘Stable operation

The flame monitoring system ensures safe and reliable combustion process.

Application field

Gas boiler burners are widely used in the following fields:

🔘Heating system: such as heating boilers for homes, office buildings, and schools.

🔘Industrial boilers: such as steam boilers in factories and power plants.

🔘Hot water supply: such as hot water boilers in hotels and hospitals.
