Secondly, close the surface blowdown valve of the gas-fired boiler to prevent other faults of the boiler. Then, quickly close the main steam valve to prevent the gas boiler drum from losing water.

Thirdly, close the deaerator air supply valve, the main power switch and the natural gas valve. The air inlet of the gas-fired boiler burner should not be blocked to reduce the area of the air inlet, and the room ventilation should not be blocked to avoid the formation of toxic and harmful gases.
