摘　　要：围绕某电力集团燃煤机组的汞排放量估算,建立了该集团燃煤电厂汞排放量估算模型。依据机组类别和实际汞排放测试结果,确定典型燃煤机组的排放影响系数。对该集团的燃煤机组汞排放量估算表明,2011年该集团所有机组汞排放都能满足国家环保要求。根据评估结果提出了符合目前燃煤机组实际情况的最有效的汞控制策略:改进汞吸附剂和利用现有污染物控制装置对汞进行联合脱除。Centred on the estimation of mercury emission from coal-fired power plants of one energy group in China, a model for estimating mercury emission from coal-fired power plants of the energy group in China has been established. According to classified kinds and practical results of mercury emission test, the emission-affecting coefficient TFi of partial coal-fired boilers in typical power plants has been primarily determined. All the coal-fired power plants in the group can satisfy the state environmental protection requirements in 2011. According to the mercury emission status,the improvement of mercury absorbents and efficient utilization of the existing air pollution control devices are so far considerd to be practically effective for mercury emission control in coal-fired power plants at present.
