摘要
烧结烟气脱硫脱硝是近年来国内外脱硫脱硝技术研究的热点之一。介绍了循环流化床脱硫+SCR脱硝技术、密相塔半干法脱硫+臭氧脱硝技术在河钢唐钢烧结机的应用情况,分析了两种技术的主要特点及存在问题,对其技术经济及减排效果进行了比较。
Sintering flue gas desulfurization and denitrification is one of the hotspots in the research of desulfurization and denitriHcation technology at domestic and foreign in recent years.The application of circulating fluidized bed desulfurization+SCR Denitrification technology and dense tower semi-dry desulfurization+ozone denitration technology in sintering machine of Tangsteel has been introduced.The characteristics and key problems of the above two technologies has been analysed.And then the technical economy and emission reduction effects of the two technologies are compared.
