Abstract: Solid fuel is acted on by a gasifying medium in a fluidized bed W. The resulting gas enters a cyclone 20 having an outlet for solid particles connected to a gasification chamber 30 in which the particles are gasified by a separate stream of gasifying medium supplied by an injector 25.

Abstract: A process and apparatus for material processing, in particular for producing gas from carbon-containing material, are disclosed. Feed material comprising particulate material is continuously formed into briquettes and is simultaneously introduced into a processing compartment. The feed material is formed into briquettes by one or more pressure wheels forcing the material through channels in a die.

Abstract: A single reactor is used for gasifying solid fuels of a wide range of particle sizes without first comminuting the particles to a common size. The larger particles are gasified on a fixed bed, and the smaller ones are gasified on a fluidized bed. In the reactor, the fluidized bed is arranged above the fixed bed and gases rising from the fixed bed help to fluidize the fluidized bed. In addition, a dust gasification region can be provided above the fluidized bed.

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.
