Abstract: The four plate types of GasGas Heater(GGH)heating element were introduced, and the influence of different plate type on the GGH selection was analyzed. Combining with the practical operation of domestic power plant FGD system, the relation between the plate type of GGH heating element and blocking in limestonebased wet FGD system was expounded, and some suggestions for solving the blocking problem were given.

Key words: Limestone-Based wet FGD, Gas-Gas Heater (GGH), heating element plate type, blocking
