Abstract：China energy structure decides that the power supply in China will depend on coal-fired power plants in long-term,therefore,pollutants control is the problem to be solved urgently in the coal-fired power plants.Under the premise of pollutant emission standards,improving the economic benefits of power plant is being focused on.For a comprehensive evaluation on the environmental and economic performance of a typical environmental protection engineering project in power plants,the evaluation index system was built,the index weight matrix according to the actual operation parameters and technical requirements was established,and the power plants typical pollutants control unit (FGD desulfurization,SCR denitrification,and electrostatic dust removal) of the comprehensive evaluation model of environmental and economic benefits were set up by using a fuzzy mathematics comprehensive evaluation method.Its evaluation results can reflect the pros and cons of environmental and economic performances of existing pollution control units,thus,the specific problems and its causes of the existing pollution control units are revealed,which is useful for the development direction of energy conservation and emissions reduction.
