随着中国煤炭消费量的快速增加，燃煤电厂的汞排放已经引起了全球的关注。本研究对中国煤中汞含量以及颗粒物、二氧化硫和氮氧化物控制装置的脱汞效果进行了深入的文献综述。为编制中国燃煤电厂汞排放清单，建立了燃煤电厂汞排放概率因子模型。对2008年中国燃煤电厂汞排放总量的最佳估计为96.5t(P50)，可信区间为57.3t(P10)至183.0吨(P90)。2005-2008年期间，二氧化硫控制措施产生的汞去除协同效益为33.9吨。开发了两个能源情景和三个污染控制情景，以预测中国未来汞排放的趋势。能源结构的变化和节能将在未来20年的汞减排中发挥重要作用。在..。
With the rapid increase of coal consumption in China, the mercury emissions from coal-fired power plants have drawn global attention. In this study, a literature review on the mercury content of coal in China and the mercury removal efficiencies of particulate matter, SO2, and NOx control devices was conducted thoroughly. A probabilistic emission factor model was established to develop the mercury emission inventory for coal-fired power plants in China. The best estimate for total mercury emissions from coal-fired power plants in China was 96.5 tons (P50) in 2008, with the confidence interval from 57.3 tons (P10) to 183.0 tons (P90). The synergetic mercury removal benefit from the SO2 control measures during 2005–2008 was 33.9 tons. Two energy scenarios and three pollution control scenarios were developed to forecast the future trend of mercury emissions in China. The change of the energy structure and energy saving will play an important role in the mercury emission reduction in the next 2 decades. Under...
