Introduction of natural gas burner unit for boiler

1. Brief introduction of natural gas burner unit for boiler

The unit is mainly composed of natural gas valve group, burner,  automatic ignition device, flame monitoring device, fire protection device, high-temperature flue gas heat recovery device, load regulating mechanism and air supply unit system.
It is designed according to boiler load, furnace structure, furnace pressure, low calorific value of gas, pressure, density, temperature, white number and other parameters.

2. Main functions of natural gas burner unit for boiler

1）Energy conversion function: the unit can convert the internal energy (chemical energy) of natural gas into heat energy for boiler heating.
2）Automatic flameout protection function: the unit suddenly flameout during normal operation (such as flameout caused by sudden absence of gas source or power failure), then the highly sensitive flame monitor will give an alarm signal to the programmable controller, and the unit will automatically shut down.
3）Protection function for low or high gas pressure: the unit can automatically shut down when the gas supply pressure is lower than the lower limit value or exceeds the upper limit value to ensure system safety.
4）Low air supply pressure protection function: the unit can automatically shut down when the air supply pressure is lower than the set value.
5）Automatic furnace purging function: when the unit is running, it will automatically purge the furnace first, and then ignite a small fire. After the flame is established, open the main fire again, without deflagration, and the combustion is stable.
6）Interlock protection function with boiler operation: interlock protection with boiler through automatic control system.
