Abstract: The surface area of raceway has great influence on the heat and mass transfer in raceway. Based on the physical simulation of COREX melter-gasifier, the Euclidean and the fractal theory are applied to determine the surface area of raceway. The results show that the surface area determined by fractal method is greater than that by Euclidean method. The surface area of raceway increases with the increasing of blast volume and discharging rate, while it decreases with the increasing of bed packing height.
