PLANT AND METHOD FOR THE THERMAL TREATMENT OF SOLIDS

A method and its related plant for the thermal treatment of iron containing oxide, in which fine-grained solids are heated in a preheating calcining stage and are exposed to a reduction gas in a subsequent reduction stage. Off-gas from the reduction stage is guided through a separation device wherei...

Beschreibung
Zusammenfassung:	A method and its related plant for the thermal treatment of iron containing oxide, in which fine-grained solids are heated in a preheating calcining stage and are exposed to a reduction gas in a subsequent reduction stage. Off-gas from the reduction stage is guided through a separation device wherein the water originating from the reduction stage is separated. The off-gas from the preheating calcining stage is guided through a venturi scrubber and a packed bed section downstream of the venturi scrubber to condense water vapor.
