Setting of sealing fan

1. In the flue gas system, each double baffle is equipped with a clean flue gas seal and an air seal. During the operation of the FGD, the bypass baffle on the same flue gas adopts a clean flue gas seal. During the maintenance of the FGD, the inlet double baffle and the clean flue gas outlet baffle adopt an air seal to prevent flue gas from entering the FGD.
2. Clean flue gas sealing is used for the original clean flue gas in GGH, and air sealing is used around GGH to prevent flue gas from leaking into the atmosphere.
3. Air sealing is used between the shaft and the casing of the booster fan to reduce the corrosion of the shaft and casing by smoke.
