Banking fire is a special technical measure for large-scale CFB boiler to dispose defects appeared in the air and flue gas system under condition of boiler shutdown without stoppage of the steam turbine

thus

it can avoid the times of un-necessary non-scheduled outage of units.Banking fire has certain effects upon boiler

steam turbine

generator

and power grid etc.

it can result in tube-burst due to overtemperature of the water-wall

the superheater and the reheater in boielrs

leading to violent variation of steam temperature from turbine

and vibration of unit

as well as excessive low load of the generator

and the temperature of cooling water in stator can't be controlled

and resulting in low frequency oscillation within the network

seriously threatening safe and stable operation of the units.
