A method and apparatus for gasifying a solid carbonaceous material such as coal is disclosed in which powdery coal is top-blown together with oxygen gas and steam onto a molten metal bath through a non-immersing multihole lance, said powdery coal is blown separately from the oxygen gas and steam, and the steam is commingled with the oxygen gas within the lance before they are injected out of the lance.

Coal gasification apparatus

A gasification apparatus utilizing a molten metal bath is disclosed. The apparatus comprises:

Apparatus for gasification of solid carbonaceous material

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.
