烧结烟气循环技术研究进展与展望

Research progress and prospect of sintering flue gas recycling technology

随着环保对钢铁企业的约束日益加强,人们环保意识的日益提高,烧结工序的节能减排工作势在必行。烟气循环技术是一种集节能与减排于一体的烧结技术,近年来在国内得到快速发展。文章综述了烧结烟气循环技术的发展史、工艺、节能减排效果及其对烧结生产的影响,对烧结烟气循环工艺的投建及运行有一定指导意义。最后对使用烟气循环过程中需要注意的事项和发展趋势做了阐述。

With the increasing restriction of environment protection on iron and steel and the increasing awareness of environmental protection,the energy conservation and emission reduction of sintering process is imperative.Sintering flue gas recycling technology,as a technology for energy conservation and pollutant emission reduction,has developed rapidly in china in recent years.The history of sintering flue gas recycling technology process,energy conservation and pollutant emission reduction,and effect on sintering production were introduced in detail,which has certain guiding significance for the construction and operation of sintering flue gas circulation process.Last,the matters needing attention in the process of using flue gas circulation and the developing trend were expounded.
