摘要： 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.

摘要： 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.

摘要： A gasification apparatus utilizing a molten metal bath is disclosed. The apparatus comprises:a gasification chamber of the closed type, which is provided with a product gas recovery port and at least one top-blowing lance, and which maintains said molten metal bath;a slag discharge chamber of the closed type, which is communicated with said gasification chamber;a means for allowing a molten slag on the molten metal bath in said gasification chamber to flow into said slag discharge chamber;a pressure controlling means for controlling the pressure of said slag discharge chamber so as to control the level of the molten slag in said slag discharge chamber;a means for discharging the molten slag from said slag discharge chamber when the level of the molten slag in said slag discharge chamber reaches a predetermined height; anda slag collecting chamber of the closed type which collects the slag discharged out of said slag discharge chamber, said slag collecting chamber being in fluid communication with said slag discharge chamber so that said molten slag in said slag discharge chamber may flow into said slag collecting chamber.
