摘　　要：针对一340 MW燃煤机组配置两种不同烟气处理方式(湿式电除尘系统与化学团聚强化除尘系统)的运行情况进行了对比分析,考察了两种烟气处理方式对尾部烟气运行参数(负荷、粉尘质量浓度、SO_(2)质量浓度、NO_(x)质量浓度、O_(2)体积分数、含湿量)的影响规律,并综合对比了两种烟气处理方式的优缺点,为燃煤机组超低排放改造选取合适的烟气处理系统提供了参考依据。The operation conditions of two different flue gas treatment methods of 340 MW coal-fired unit with the same configuration, wet electric dust removal system and chemical agglomeration enhanced fine particles removal system, were contrastively analyzed. The influence of two flue gas treatment methods on tail flue gas operation parameters(load, dust mass concentration, SOmass concentration, NOmass concentration, Ovolume fraction, moisture content) was investigated. Moreover,the advantages and disadvantages of the two flue gas treatment methods were compared comprehensively. The results provide a reference for selecting a suitable flue gas treatment system for ultra-low emission transformation of coal-fired units.
