摘要: 燃煤烟气中SO3的存在对于燃煤电站运行、周围环境及人体健康均具有严重危害。为有效降低燃煤烟气中SO3含量,在深入分析燃煤烟气中SO3来源及硫酸雾形成的基础上,介绍了国内外抑制燃煤烟气中SO3生成及有效降低其排放的控制措施,同时分析了各技术的优劣,认为优化脱硝系统操作条件及采用湿式静电除尘器是目前较为有效的2种控制SO3的技术。

Abstract: The SO3 in coal-fired flue gas is harmful to the operating conditions in coal-fired power plants, the environment and the human health. To effectively reduce the SO3 content in flue gas, based on the in-depth analysis on the sources of SO3 and the formation of sulfuric acid mist, the control measures employed both at home and abroad to inhibit the formation of SO3 and reduce its emissions are presented. Meanwhile, the pros and cons of the technologies are analyzed. With the technology analysis, the denitration operation condition optimization and the wet electrostatic precipitator are considered the better ones in effectively controlling SO3.

Key words: coal-fired power plant, flue gas, SO3, pollution control
