摘　　要：在对某 30 0 MW燃煤电站锅炉的煤、渣、底灰、飞灰进行取样后 ,通过对煤样、灰样、渣样中的汞进行定量测量 ,并借助于质量平衡分析方法计算烟气中汞的浓度 ,获得了煤在大型电站锅炉中燃烧时汞污染物的分布特征及其排放特性。图 5表 1参After coal, slag bottom ashes and fly ashes from a 300MW utility boiler at the loads of 300MW were sampled, mercury contents of those samples are measured. By means of mass balance methods, mercury distribution in coal and its combustion products can be calculated. Therefore, characteristics of mercury formation and emission in large scale utility boiler are discussed and analyzed.Figs 5, table 1 and refs 9.
