Expansion port, leakage rivet joints; tube, the waterwall tubes, damage to the heating surface tube leakage; drum in contact with the flue gas, set top box, a heat insulating material off the downcomer; water supply system, a combustion system, the occurrence of breakage safety accessories . Shutdown of the gas boiler normal (full shutdown, maintenance shutdown) Step 1, in order to stop the burner, for closing the valve. At the same time feed water to the boiler, 2cm above the normal water level reaches the stop water supply, reduce the pressure. 2, close the main steam valve, open the traps, steam boiler, water cut off. 3, the electric boiler feed water control valve closed and the manual valve, boiler feed water cut. 4, steam pressure may be lowered to the water supply and drainage operations alternately 0, the pot water temperature is gradually lowered. When the temperature dropped to 50 ℃ (not hot when hand potshell head with or touch), the entire pot of water may be drained. Should be preceded by opening the drain valve or air valve above the boiler, this time into the furnace maintenance, shutdown must be kept slow cooling, rapid cooling is prohibited. From the shutdown to be able to enter the furnace maintenance, cooling time is not less than 24 hours. 5, sales of more than 24 shutdown, to total gas supply valve is closed, opens the gas pipe to completely drain the subjective dispensing gas.
