A reactor for gasifying solid fuels, particularly coal, comprises with the fixed bed of fuel at least one stirring arm, which is rotatable about a vertical axis and is approximately triangular in cross-section. The forward knife edge and the rear crushing edge of the stirring arm are provided with replaceable armoring. The armoring at the knife edge consists of a plurality of armoring elements (7), which are approximately V-shaped in cross-section and are arranged one beside the other so as to define an expansion joint. The armoring at the crushing edge consists also of a plurality of elements (10), which are mounted on the stirring arm so as to be movable at ambient temperature. |
