摘　　要：燃煤是汞最大的排放源,而汞又是煤中最易挥发的重金属元素之一,由于汞的剧毒性、积累性及停留时间等特点,汞污染问题引起越来越多人的重视。文中论述了汞的排放形态及其特性,并分析了燃烧前脱汞、燃烧中脱汞和燃烧后脱汞等方面的技术,燃烧后脱汞应用较广泛。The coal-fired power plant is the largest emission source of mercury. Mercury is one of the most volatile heavy metal in coal. Because of the highly toxin, the accumulation and the long residence time of mercury, the problem of mercury pollution attracts more and more peopleb attention. This paper described the shape and characteristics of the emission of mercury. It also analyzes control technology for pre-combustion, during-combustion and post-combustion. Among them, technology applied for post-combustion is being widely used.
