| 摘 要： | 从烧结过程燃料用量、混合料水分、烧结矿碱度及混合料含硫量研究烧结工艺参数对烧结烟气中SO2排放的影响，发现烧结过程SO2的排放不受烧结工艺参数及原料含硫变化的影响，在烧结终点前始终存在一个排放浓度峰值区间，揭示烧结烟气SO2排放的自持性规律是由于烧结料层有选择性吸附SO2作用所导致，SO2的排放遵循硫化物、硫酸盐热分解生成-料层吸附-再分解-解吸的迁移及循环富集排放机理。

| Abstract: | The effect of sinter technology parameters,including coke ratio,moisture,basicity and sulphur content in sinter mix,on the emission of SO2 in sintering flue gas was studied.The results show that the emission of SO2 rises to a peak value rapidly just before the sintering end point and declines dramatically no matter how parameters of sinter technology and the properties of raw material change.The self-sustaining characteristics of SO2 emission results from the selectively adsorbing SO2 by sinter bed,and the ... |
