For collection of dust from gases at temperatures up to 900.degree. C. and under presssures up to 20 bars by means of gas-permeable two-dimensional filter elements, an apparatus is proposed which comprises a pressure-resisting cylindrical outer housing, which contains a gas-tight pear-shaped inner housing, which is movably mounted in the outer housing by a means of a heat-insulating carrying structure and is provided with a tubular gas-outlet port and comprises a cambered bottom, which contains cylindrical filter elements. A pressure-confining gas-tight compensator is provided between the tubular gas-outlet port of the inner housing and the outer housing. Because the 'pressure-confining' and 'supporting' functions are separate, the internal components, which will be subjected to temperatures up to 900.degree. C., can be joined to the pressure-confining wall of the outer housing, which must not be heated above 200.degree. C.

Apparatus for removing dust from gas

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.
