The use of gas boiler in the process of ignition, point is the most common fault.Gas boiler in the use of the process, the most likely to fail to start fire, resulting in the gas boiler can not work normally, burritt boiler manufacturers for you to introduce the gas boiler can not start several common reasons.
Common reasons why gas-fired boilers fail to ignite:
I. igniter fault: if one of the impulse igniter and controller fails, the gas-fired boiler cannot be started.Set the boiler ignition pressure too high or too low, no longer within the ignition range.
Treatment: check the boiler pressure to see if the pressure is in the ignition pressure range of the burner, it can be operated in the control cabinet.
Gas fired boiler cannot fire
Two, the gas inlet pressure is too low or too high, the burner does not ignite.
Treatment: check the combustor inlet pressure gauge to see if the pressure is composite boiler ignition pressure
Iii. Water level problem: the water cannot flow through normally due to the blocking of the filter net at the inlet of the gas-fired boiler. The water level of the boiler is too low, which is lower than the ultra-low water level of the boiler
Treatment: check the boiler water level, whether it is lower than the boiler ultra-low water level, clean the filter plug.
Four, solenoid valve fault: if the gas boiler ignition only hear the ignition sound, no solenoid valve "click" magnetic absorption sound, may be the solenoid valve damage or aging, electromagnetic valve aging, will not be controlled, in the beginning of the fire can be absorbed under one, play fire, but then closed and shut off;Before confirming the solenoid valve good or bad to confirm the igniter control circuit can be normal, if there is a problem, can not control the solenoid valve suction.The burner is not reasonable to adjust the gas and control the air distribution.
Treatment: gas and air debugging ratio is not correct, the air into the air is too big, fire automatically after ignition
Five, natural gas leakage, combustion machine ignition.
Treatment: general combustion machines are equipped with leak detection device, can be monitored by themselves.
Vi. The smoke pipe cannot exhaust normally.Gas boiler smoke pipe has infarct, clearing smoke pipe infarct smoke pipe is too long, not the correct device.Exhaust temperature is too high, boiler automatic chain protection, combustion machine does not fire.
Treatment: check the boiler exhaust temperature, to see if it is higher than the boiler smoke temperature
Seven, water and gas linkage installation problems: gas boiler water and gas linkage valve drum aging or damage can not promote the micro switch;The micro switch is broken.
Viii. The emergency stop switch of the boiler is operated by mistake, and the burner is not ignited (the boiler is not running)
Processing method: at this time generally all the functions are not available, you can monitor their own.
