Since the flue gas medium transported by the boiler high-temperature exhaust fan contains a lot of dust, a lot of dust often accumulates in the high-temperature exhaust fan. At the same time, the large amount of dust can easily cause the impeller to stick and lead to insufficient dynamic balance of the rotor in the fan. Due to the insufficient dynamic balance of the fan rotor, the fan vibration will be aggravated, and the dust will cause the fan to trip, thus forcing the shutdown.
