Abstract: The control of electrical damper of air and flue gas system concerns safety and stable operation of boiler. Especially, in fault treatment process of air and flue gas system, if the air and flue gas system electrical damper could not be closed correctly and timely to isolate the fault, the fault will be enlarged. The hidden hazard existed in air and flue gas system electrical damper control logic of 4×300MW+2×600MW units in Sichuan Guangan Power Generation Corporation Limited was analyzed, and an improvement suggestion was put forward.

Key words: air and flue gas system, electrical damper, control logic, improvement measure
