Dry Sodium Bicarbonate Duct Injection FGD is suitable for the tail gas treatment of gas-fired boilers and hot stoves in iron and steel industries with sulphur content less than 1000mg/Nm, and the optimum reaction flue gas temperature is about 200 C. 2.Technological principle.
Read MoreBroadly, dry and semi-dry FGD processes include furnace/duct sorbent injection using sodium/calcium-based reagent and the spray drier absorber (SDA) technology using slaked lime or limestone as reagent. An SDA system uses a roof gas disperser, a central gas disperser for dispersing flue gas and an atomiser to spray the reagent slurry.
