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 device for agglomerating the coal to be gasified located on the container, and a continuously operable screw conveyor which feeds the coal to be gasified to the agglomerating device which delivers the formed agglomerates, in a green condition, into the container. The feed device is encapsulated and, together with the fine coal and agglomerates within it, forms a gas tight closure for the container to maintain the pressure therein.
