Wet flue gas desulphurization (FGD) plants with forced oxidation, installed at coal and oil fired power plants for removal of SO 2 (g), must produce gypsum of high quality. However, quality issues such as an excessive moisture content, due to poor gypsum dewatering properties, may occur from time to time.

In China, the resource utilization processes of FGD gypsum are mainly used for wallboard production and as cement retarder. For the wallboard production, FGD gypsum first needs to be dried (at temperatures < 128 °C) to remove any free moisture, and then to be calcined (128–163 °C), to produce β-CaSO 4 •1/2 H 2 O. Subsequently, it …
