摘要：

In this paper the situation of SO2 discharge and pollution in Chinese coal-fired power plants is briefly introduced, and it is described the advantage and disadvantage of eight kinds of flue gas desulfurization (FGD) method used in coal-fired power plants. Especially an economic FGD method which is called Wet limestone desulfurization and dust-removal facility (simply called PXJ)is discussed carefully. Its desulfurization principle,operational parameters,technological process are given in the paper. A 2 x 125MW power plant is illustrated as an example for this FGD method. Its investment is only one-tenth of imported FGD, its operational cost is only one-third of imported FGD, and its desulfurization efficiency is over 80%.
