It is important to maintain a molten slag discharging from the slag-hole in order to make a stable operation of the coal gasifier. To discharge the molten slag constantly, a temperature of the molten slag has to be higher than the ash fluid temperature. The heat transfer in the coal gasifier, especially the radiative heat transfer, controls the temperature of the molten slag. In this paper, a numerical simulation of the heat transfer in the coal gasifier with radiation is carried out, and a heating value of the surface around the slag-hole is calculated. As a result, an influence of the slag-hole shape and coal burner arrangement on the heating value is predicted.
