摘　　要：某地区为使循环流化床锅炉的SO2排放浓度达到GB13223-2011和当地政府100 mg/Nm3限值要求,结合福建无烟煤含硫量低的特点,比较分析中小型循环流化床锅炉常用的石灰石/石膏湿法(FGD)、烟气循环流化床干法(CFBFGD)、炉内喷钙-尾部加湿活化法(LIFAC)等脱硫方式的优缺点,并介绍了多炉一塔湿法脱硫装置在中小型循环流化床锅炉中的应用情况。In order to meet the requirements of GB13223-2011 SO2 emission concentrations and 100 mg / Nm3 local government limitation for the Circulating fluidized bed boiler,the advantages and disadvantages of some commonly used desulfurization methods for the small and medium sized CFB were compared and analyzed,such as the wet limestone / gypsum（ FGD）,flue gas circulating fluidized bed dry（ CFB-FGD）,and spraying calcium inside the furnace tail humidification activation method（ LIFAC）,combining with the lowsulfur content of Fujian anthracite. And the application of the wet desulphurization device for multi-furnace with one tower in the small and medium sized CFB also presented in this paper.
