Abstract
Burners are often used in ore fusing furnace and the propagation of the thermal energy is dominantly heat radiation. Since the initial ore temperature is low, it will be molten by radiation thermal energies. However, ore will not melt enough and affect product quality. The improvement of product quality can be desired if such a phenomenon in a furnace can be grasped in numerical analysis. Here general-purpose FEM analysis code ANSYS/FLOTRAN is used. Authors devised the analysis by separating radiation analysis and thermal fluid analysis and defining radiation boundary conditions using array variables.
