摘　　要：针对火电厂烟气中烟尘、SO和NO的环保超低排放要求,本研究对全国80家火电厂、287台燃煤机组进行了大气污染防治现状调研,结果显示,73.7%机组SCR出口NO排放浓度在100mg/m^3以下,68.3%机组除尘器出口烟尘浓度在30mg/m^3以下,81.4%机组脱硫装置出口SO排放浓度在200mg/m^3以下;55台机组实施了超低排放改造。根据调研情况及现有工程案例,提出了火电机组实现超低排放采取的技术路线:SCR脱硝增效+ESP除尘增效+FGD脱硫增效+WESP除尘,最后给出了火电行业实施超低排放的建议。Based on the emission requirement of dust, SO2 and NOx from the flue gas of power plant, the researches on the current situation of air pollution control are conducted in 80 power plants and 287 coal-fired generating sets. According to the research situations and existing engineering cases, the technical route about ultra-low emissions of the power generating sets are put forward in this study. Finally, the suggestions for the implementation of ultra-low emission in power industry are proposed.
