Abstract

Abstract: In order to understand the current situation of environmental protection and the environmental protection facilities in China's gas power plants and grasp the trend in future environmental protection policies, research and study have been conducted on multiple gas-fired power plants in typical regions of China . The status of the emission reduction technology on NO_x, which is the main pollutant from gas power plants, and its existing problems of are analyzed from three aspects of the control of gas turbine combustion, the control of waste heat boiler SCR and the control of external factors. It is concluded from the comparison that the waste heat boiler SCR control technology is more mature and cost-effective and could be one of the the effective nitrogen reduction means for gas power plants in the future. Considering the domestic and foreign emission level and technical status, it is clear that the environmental protection standards on gas power plants in China is tending to be more stringent. Finally, Opinions and suggestions on reducing nitrogen emission are put forward from the aspects of power plant operation, scientific research and policy formulation.

Key words: gas power plant, nitrogen oxides, emission status, emission reduction technology, environmental standards
