摘　　要： 通过对燃煤电厂湿烟囱条件下SO_x排放形态分析指出,烟气中SO_x在烟囱出口处基本以硫酸雾形态排放,硫酸雾和烟气中的细颗粒物是大气中硫酸盐气溶胶的重要来源物,也是致霾重要来源,采用GGH提高烟气温度能够有效控制烟气中SO_2转化为硫酸雾,深度脱硫是有效降低硫酸雾排放浓度的根本措施。 This paper analyzes the forms of SOx discharged from a wet chimney of a coal-fired power plant, deduces that SOx are almost in the form of sulfuric acid mist when discharged from the export of the chimney,and that the sul- furic acid mist and fine particles in flue gas are important sources of sulfate aerosol in the atmosphere, as well as haze and fog. It is also pointed out that by using GGH to raise the temperature of the flue gas, the concentration of dis- charged sulfuric acid mist,which is transformed from SO2 , can be reduced effectively. Deep desulfurization is the bas- ic measure to reduce the concentration of discharged sulfuric acid mist effectively.
