摘　　要：烧结工艺排放的SO2量约占钢铁生产的60%,传统上采用低硫原料配入、高烟囱扩散稀释等控制方法,已不能适应脱硫减排新形势。福建三钢在CFB-FGD半干法脱硫工艺基础上大胆创新,在设计上采用了双大烟道、双主抽风机工艺配置的烟气选择性脱硫技术方案,为解决钢铁行业烧结脱硫难题提供了参考。The amount of SO_2 from sintering process is over 60% of iron and steel production.The traditional control methods are not suitable for the new situation of desulphuration and reduction of pollution.A new technique of desulphuration of flue gas,where double-flue and twin suction fan are used,is developed by Fujian Sanming Steel Group,based on CFB-FGD semi-dry process,which provides a new example for solving the difficult problem of sintering desulfuration in iron and steel industry.
