摘　　要：对石灰石/石膏湿法烟气脱硫塔进、出口的SO3测试数据进行了分析,在此基础上讨论了石灰石/石膏湿法烟气脱硫系统对烟气中SO3的脱除作用以及脱硫后烟气中SO3的存在形式和来源,并分析了脱硫后续设备的腐蚀趋势。The test results of sulfur trioxide （SO3） measured in inlet and outlet of wet limestone/gypsum flue gas desulphurization system were analyzed. The sulfur trioxide （SO2） removal efficiency of wet limestone/gypsum flue gas desulphurization system was discussed. The existence form and source of sulfur trioxide （SO3） in flue gas streams after tower was analyzed. The corruption trend of the devices installed after the desulfurization scrubber was proposed.
