摘　　要：我国是燃煤大国,汞污染严重,其危害性已被广泛关注。在大量文献调研的基础上,介绍了汞的形态分布和监测方法,重点分析了汞形态转化的影响因素如煤种、气体组分、烟气温度、燃烧方式、过量空气系数等。最后提出了燃煤电厂在废气处理设施设计和建设时预留汞控制设施的位置和空间的建议。China is a burning coal country, so mercury pollution is serious, which has been widely noted. Based on a lot of research on literature, this paper introduces the species distribution and monitoring methodologies of mercury and analyzes the affecting factors of mercury form transformation such as coal, gas component, flue gas temperature, combustion, etc. A suggestion of flue gas treatment facilities of coal-fired power plant should reserve the position of mercury control facilities and space at the time of design and construction is proposed at last.
