摘　　要：针对燃煤电厂烟气汞污染问题,分析了汞在烟气中的分布形态,并基于燃煤电厂对常规大气污染物烟尘、SO_(2)以及NO_(x)实施超低排放的背景,研究了脱硝、除尘、脱硫设备对不同形态汞协同控制的技术特点和效果,为燃煤电厂将来实施更为严格的汞排放标准后技术的选择和新型烟气脱汞技术的研发提供参考。Aiming at mercury pollution in flue gas of coal-fired power plants,the distribution patterns of mercury in flue gas were analyzed.Based on the background of ultra-low emission of conventional air pollutants such as soot,SO_(2) and NO_(x) in coal-fired power plants,the technical characteristics and effects of collaborative control of different forms of mercury by denitrification facilities,dust removal equipment and desulphurization system were studied,providing a reference for the selection of technologies after the implementation of more stringent mercury emission standards in coal-fired power plants and the research and development of new flue gas mercury removal technologies.
