A reactor for the pressure gasification of coal by treatment with oxygen and steam and, if desired, additional gasifying agents, at elevated temperatures and pressures, includes a water-cooled jacket and a rotary grate for moving the material to be gasified and for distributing the gasifying agents introduced into the reactor. The rotary grate is made of at least two concentric parts each of which rotates independly of the other part.

Reactor for the pressure gasification of coal

Lump fuels are continuously coked at a high temperature above 750.degree. C in a shaft oven with direct heating by a hot scavenging gas which is produced by a partial combustion of the coking gas and conducted through the shaft oven in a countercurrent to the lump fuel. A reactive carbonaceous material is added to the hot scavenging gas before it enters the high-temperature coking zone and reacts with the gasifying agents (carbon dioxide and water) contained therein before it is introduced into the shaft oven.
