摘　　要：影响烟气脱硫 (FGD)经济性的因素有FGD工艺的类型 ,建设FGD的电厂和机组的状况 ,现有机组FGD的改造因子。FGD经济评价的指标有 :工程总投资、单位容量造价、年运行费用、脱硫成本、售电电价的增加、改造因子。计算改造因子时 ,影响因素有 :范围调整、工艺因子、地点因子、改造难度。The factors influencing on the economy of FGD include the type of FGD process, conditions of power plant construction and unit with FGD, the FGD reforming factors of the existing units. The indexes for FGD economic appraisal include the total engineering investment, unit capacity cost, annual operation cost, desulphurization cost, increment of electricity sale price and reform factor. For calculating the reform factors the influence factors cover the range of regulation, process factor, location factor, difficulty of reform. A detailed description is given for the economic appraisal method.
