Abstract:

Abstract:The limestonegypsum wet desulphurization technology is widely used in domestic large thermal power units, and its byproduct gypsum was used more and more widely. The water content of the gypsum is an important index for evaluating the desulphurization system operation. Taking the Qinghai Huadian Datong Power Generation Company Limited as example, the factors influencing on water content of gypsum in practical desulphurization system operation were analyzed. The result in this paper provides certain reference for improving the desulphurization gypsum quality.
