Flue gas desulfurization(FGD) is an effective technique to remove SO2 gases of coal-fired plants. Limestone is usually used as desulfurizing agent. In this study, we use the limestone sludge which is a by-product of steel industry in order to replace desulfurizing agent of FGD process. Physical and chemical characteristics analysis of desulfurizing agent was conducted.

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998. Get Price
