The gypsum slurry discharged from the absorption tower is concentrated and dehydrated to make the water content less than 10%, then the gypsum slurry is conveyed to a gypsum storage bin by a conveyor to be stacked, the desulfurized flue gas is treated by a demister to remove fog drops, and the flue gas is heated by a heat exchanger to be heated and then is discharged into the atmosphere through a chimney.
