Discussion on problems existed in carbide slag wet FGD system

Now the limestone-gypsum wet FGD is becoming the first selectable flue gas desulfurization technology in our coal-burning power plants.If the absorbent limestone can be replaced by more inexpensive carbide slag,the waste canbe reused.and the cycle economy is reached.The problem excisted in the operation of carbide slag wet flue gas desulfurization are described,and some suggestion are presented.
