为提高烟气脱硫效率，在分析循环流化床脱硫工艺的基础上，根据煤质分析，选取了系统的烟气设计参数和脱硫剂参数并对脱硫效率进行分析。结果表明，循环流化床烟气脱硫技术与炉内喷钙法相结合可以达到90％的脱硫效率，SO2的排放浓度小于200 mg / m3，可以满足?锅炉大气污染物排放标准?的相关要求。与湿法脱硫技术相比，循环流化床烟气脱硫技术具有设备紧凑，投资少，占地小，特别适用于现有机组的改造工程，脱硫剂利用效率高，脱硫产物为干灰，不会产生二次污染等优点。但循环流化床烟气脱硫技术也存在着脱硫效率较湿法脱硫技术偏低，对锅炉负荷的变化适应性差，运行控制要求较高等不足。

In order to improve flue gas desulfurization efficiency,this paper first analyzed the desulfurization technology of circulating fluid-ized bed,then chose the system design parameters and desulfurizer based on the coal properties.At last,the authors analyzed the desulfu-rization efficiency.The results showed that the combination of the technique and furnace sorbent injection technology improved the desulfu-rization efficiency to 90%.The SO2 emission concentration was less than 200 mg/ m3 and met the Standards for Boiler Discharge of Atmos-pheric Pollutants.Compared with the wet FGD technology,the technique had the advantages of compact structure,small investment,high ef-ficiency,dry desulfurization product and without secondary pollutants.While its disadvantages also existed such as low desulfurization effi-ciency,poor adaptability dealing the changes of boiler load,higher operational control requirements.
