摘　　要：基于2012年江苏省10家典型燃煤电厂相关数据,分析了影响烟气中汞(Hg)排放浓度的因素。其中电厂负荷、烟气净化设施、燃烧炉类型等会直接影响烟气中Hg的排放浓度,而原煤中Hg的含量与烟气中Hg的浓度没有直接的关系。通过模型对江苏省现有300 MW以上燃煤电厂Hg排放量进行了估算,2012年Hg排放总量约为7.307 t。通过反距权重插值进行分析,发现在区域分布上江苏省整体呈现出南部高于北部的趋势。The impact factors in concentration of mercury emission from coal-fired power plants were analzied,based on the datas of 10 coal-fired power plants of 300 MW in Jiangsu province. The main impact factors were the load,the flue gas purification facilities,combustion furnace model, there were not obvious correlation between concentration of mercury and the mercury content of coal. Through the model to estimate the total mercury emission of more than 300 MW coal-fired power plant in Jiangsu province, the total mercury was emissions about 7.307 tons in 2012. By Inverse Distance Weighted analysis found that the total emission in southern higher than in the north in the regional distribution of Jiangsu province.
