摘要
介绍了烧结烟气通过湿法脱硫后,利用高炉煤气加热和GGH热交换系统,采用中低温催化剂,进行选择性催化还原,实现中低温脱硝和烟气消白的应用实例。对脱硝系统及设备作了详细的介绍。
After the wet desulfurization of fuel gas,the selective catalytic reduction of sintering flue gas is carried out by making use of blast furnace gas heating and GGH heat exchange system and adopting medium and low temperature catalysts,which realizes the application of medium and low temperature denitrification and flue gas whitening.The denitrification system and equipment are introduced in detail.
