Gasification process of solid carbonaceous material
Patent
·
OSTI ID:5859526
In a process for the 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, 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 the coal being gasified. The ratio l/lo of the depression depth L of the molten iron bath to the molten iron bath depth lo is maintained from 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 forming of an adhered mass in the furnace. A stirring gas is blown through a bottom nozzle to stir the molten iron bath.
