Abstract: The blockage of GGH by deposited dust of thermal power plant FGD system formed in long term operation seriously influence on the normal operation of the system and is harmful for energysaving and consumption reducing. In addition, serious blockage could damage the boost fan and cause the system accident tripping. The reasons of blockage of GGH by deposited dust in FGD system were analyzed, and some concrete measures for slowing the blockage of GGH by deposited dust were put forward.
