A vessel into which a solid fuel and an oxidant are introduced to be gasified therein and from which gasified fuel is discharged, has a bottom portion including a conical chamber communicating with a tubular port. A body of liquid medium is accommodated in the conical chamber and slag produced during the gasification is being entrapped therein. A tubular member has two tubular portions, one of which is accommodated in the tubular port and the other one of which is inclined with respect to the first-mentioned portion, extends into the chamber and is provided with openings connecting the interior of the tubular member with the chamber. The tubular member is driven to rotate about the axis of the port so that the second-mentioned portion cooperates with the interior surface of the chamber to comminute the slag lumps contained in the chamber. A grinding insert is rigidly attached to the port and projects into the chamber so as to enhance the comminuting process. A wear insert is removably attached to the interior wall of the chamber, and the edges of the openings are configurated as crushing portions, so that the comminuting process is further enhanced. |
