Abstract:

The design of sealing air system of flue gas damper gate for thermal power plant FGD system was introduced and optimized. Taking 2×600MW unit as

example, two sealing modes for flue gas damper gate, in which the sealing air fan and the primary air of the boiler were used respectively, were analyzed,

and their energysaving effects were compared.
