A new technology for separating and recovering iron and zinc from EAF exhaust gases is proposed. The process is composed of a coke bed filter and a new type of zinc condenser. Iron and slag components in the exhaust gas are collected in the coke bed filter. In this paper, the theoretical background and numerical analysis of the characteristics of the coke bed filter are introduced, and the experimental results concerning the collection of iron and slag components in a bench-scale coke bed filter are reported.
