摘要/Abstract

摘要： 为了解中国燃气电厂污染物排放现状及环保设施运行现状并掌握未来燃气发电的环保政策走向，通过调研国内典型地区的多家燃气电厂，从燃机本体控制、余热锅炉SCR控制以及外部因素控制等3个方面对比分析了燃气电厂的主要污染物-NO_x的减排技术现状和存在的问题，认为余热锅炉SCR控制技术的优化空间大、国内应用案例多，是燃气电厂未来降低NO_x的有效手段；基于国内外排放水平和技术现状，分析得出国内燃气发电的环保标准具有进一步加严的趋势；从电厂运行、科学研究和政策制定等多个方面提出了降低NO_x排放的意见和建议。

关键词: 燃气电厂, 氮氧化物, 排放现状, 减排技术, 环保标准

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
