ABSTRACT:
In a process for gasification of solid carbonaceous material such as coal, powdered coal is top-blown onto a molten iron bath stored in a furnace through a non-submerged lance toward a hot spot formed by means of a jet of oxygen and steam top-blown through a non-submerged lance, the coal being blown by means of a carrier gas, and flux is optionally added into the furnace by the lump or blown toward the hot spot, thereby resulting in the coal being gasified. The ratio L/L.sub.o of the depression depth L of the molten iron bath to the molten iron bath depth L.sub.o is maintained from 0.05 to 0.15, and the blowing velocity of the solid carbonaceous material is maintained from 50 to 300 m/sec so as to suppress the formation of an adhered mass on the upper part of the furnace, hood or lance.
