ABSTRACT:
The invention reveals a process and an apparatus for treating flue gas from sintering plants, in which dry additive consisting at least of adsorbent and recirculated material is added by the entrained-flow process to the flue gas from a sintering plant in a flue gas duct, and the additive is then separated out of the flue gas by fabric filters and at least partially recirculated. In this context, it is provided that additive is introduced at least one location in the opposite direction to the direction of flow of the flue gas.
