What are the safety functions of the burners of gas boilers?

The burner is a combustion device of a gas boiler. A good burner can realize automatic ignition, monitoring of combustion status, protection against ignition, flameout protection, high and low pressure protection of gas pressure, protection against insufficient air pressure, and power failure protection. What role can these functions play? Listen to FANGKUAI Boiler to introduce you one by one.

1. Automatic ignition function
       The gas burner should be equipped with electric spark ignition, which is convenient for automatic control. The ignition time is generally between 2 and 5 seconds.

2. Combustion status monitoring function
       Mainly monitor the flameout state of the gas boiler burner, and the monitoring object is the flameout signal. Once the flame detector detects this signal, the burner will automatically cut off the air supply and the burner will stop running.

3. The burner does not catch fire, automatic protection function
       When the gas boiler burner is ignited. The ignition action occurs before the ventilation. After the ignition action occurs, if the human flame detector does not detect the flame signal, the burner automatically enters the protection state.

4. Burner flameout protection
       After the burner is turned off, the temperature in the furnace of the gas boiler is still relatively high, the burner will stop running in a short time, and the supply of the gas source is automatically cut off to prevent excessive gas from entering the furnace and causing an explosion.

5. Gas pressure high and low protection
       The gas boiler burner will operate within a certain range of gas pressure, above or below this range, the burner will enter the protection state.

6. Air pressure protection function
       When the gas boiler burner is running, if the amount of air in the furnace is insufficient, it will always be inhaled, which will cause the furnace to deflagrate, which is very dangerous. Therefore, once the air in the furnace is insufficient, the burner will automatically enter the protection state.

7. Burner power failure protection function
       When the gas boiler burner is in operation, if it is suddenly powered off, it will be very dangerous. Therefore, the burner is provided with power failure protection.
