Apparatus for gasification of solid carbonaceous material

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; and a 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.
