摘　　要：围绕全国燃煤电站汞排放量估算,建立了全国燃煤电站汞排放量估算模型。根据锅炉基本特征,将全国燃煤电站划分为27类。依据划分类别和实际汞排放测试结果,初步确定部分典型电站燃煤锅炉的排放影响系数TFi。对全国燃煤电站的汞排放量估算表明,2005年除港澳台地区外,全国电站燃煤锅炉气态汞排放量约为147.014 t,固态汞排放量约为46.630 t,总汞排放量约为193.644 t,约为世界人为燃煤汞排放量的10%。Centred on the estimation of mercury emission from coal -fired power plants in China, a model for estimating mercury emission from coal - fired power plants in China has been established. Based on fundamental characters of boilers,27 kinds of coalfired power plants in China have been classified. According to classified kinds and practical results of mercury emission test, the emission - affecting coefficient Fij of partial coal- fired boilers in typical power plants has been primarily determined. The estimantion of mercury emission from coal - fired power plants shows that the gaseous mercury emission from coal- fired power plants in China was about 147. 014 t,and solid mercury emission was about 46. 630 t in 2005. The total mercury emission was about 193. 644 t, accounting for about 10% of artificial mercury emission in the world.
