摘要
介绍了燃煤电站汞的排放状况,总结了前人关于燃煤电站汞的转化过程、不同排放形式及影响其形态转化的因素,介绍了当前燃煤电站汞排放控制技术的研究进展。分析表明:燃煤电站汞的排放及控制将引起越来越多的重视,成为国内外关注和研究的热点,而如何有效地将气相单质汞转化为易被吸收或吸附的二价汞,同时降低脱汞成本将是一个主要的研究方向。
This paper presents status of mercury emissions from coal-fired utility boilers, summarizes mercury transformation, different forms of mercury emissions and their physicochemical characteristics as well as factors that may affect mercury speciation, presents some mercury control technologies. It is clear that the emission control of mercury from coal-fired utility boilers will attract more attention and become a concern both in and abroad. Attentions on how to reduce cost at the same time effectively transform elemental mercury into mercury （ Ⅱ ） state （Hg^2＋ ） that can be easily removed by absorption and adsorption should be paid in the future R ＆ D.
