System Function of FGD

System Function

(1). Limestone granules are transported to the wet ball mills via weight feeder, and ball mill system grind the granules to make limestone slurry;

(2). Flue gas from the boiler will be inducted into the absorber and contact in counter direction with the limestone/gypsum slurry and remove most of SO2, HCL, HF and so on;

(3). The oxidation fan will forcibly oxidize the calcium sulphite into calcium sulfate(gypsum);

(4). The vacuum belt system will dewater the gypsum slurry into gypsum with water content <10%, which will be transported out after being collected;

(5). The absorber slurry quality can be kept, through discharging the wastewater.
