- 1 - Abstract: The invention provides a process for gasification of solid carbonaceous material such as coal. In this process the powdered coal is top-blown onto a molten iron bath located in a furnace through a non-submerged lance toward a hot spot formed by means of a jet of oxygen and steam also top-blown through a non-submerged lance. The coal is blown by means of a carrier gas, and flux is optionally blown toward the hot spot or added to the furnace in lump form. The ratio L/Lo of the depression depth L of the molten iron bath to the molten iron bath depth Lo is maintained within the range of 0.05 to 0.15, and the blowing velocity of the solid carbonaceous material is maintained within the range of 50 to 300 m/sec so as to suppress the formation of an adhered mass in the furnace. A stirring gas is blown through a bottom nozzle to stir the molten iron bath. In this way, coal gasification can be achieved with high efficiency for long production runs.
