Abstract

Apparatus for the gasification under pressure of bituminous coal, especially fine coal, comprising a generator which has a container to receive the coal to be gasified and a feed device which supplies the coal to the container, while keeping the container closed off so as to maintain the pressure in the generator. The feed device includes a briquette forming device located on the container, and a continuously operable screw conveyor which feeds the coal to be gasified through the briquette forming device and directly into the container in the form of briquettes. The feed device is encapsulated and, together with the fine coal and briquettes within it, forms a gas tight closure for the container to maintain the pressure therein.
