Three-dimensional analysis of the walking-beam-type slab reheating furnacein hot strip mills

Three-dimensional analysis is performed for the turbulent reactive flow and radiative heat transfer in the walking-beam-type slab reheating furnace by FLUENT. A simplified burner is validated against the results of the actual burner with the detailed grid resolution to avoid an excessive number of g rids. The predicted temperature distribution in the furnace and global ener gy flow fractions are in reasonable agreement with available data. Distribu tion of the heat flux to the slabs, velocity vectors, and all major scalar variables in the furnace also are predicted This study shows that three-dim ensional analysis may be a useful fool to understand quantitatively the com plicated combustion and heat transfer characteristics in the furnace.
