ABSTRAKT
Thermal efficiency of a reheating furnace was predicted by calculating radiation heat transfer to the slabs and the furnace wall. The entire furnace was divided into fourteen sub-zones. Each sub-zone was assumed to have the homogeneous wall temperature and medium temperature. Temperature was computed for the medium and the wall of each sub-zones through overall heat balance. The radiation heat transfer was solved by the FVM radiation method. The blocked–off method was applied to the treatment of the slabs inside which intensity has no meaning.
