Abstract of the Disclosure An improvement in the process for the gasification of a solid fuel wherein the solid fuel is at least partially oxidized at a temperature above the melting point of ash of the solid fuel and at a pressure of 10-200 bar where the resultant synthesis gas is thereafter cooled in the presence of combustion residues of the solid fuel, and the combustion residues are thereafter discharged directly, the improvement residing in carrying out the gasification in a gasification zone disposed vertically over and in fluid communication with a radiation zone comprising cooling surfaces, said radia- tion zone have disposed at the bottom thereof and in fluid communication with said radiation zone a water containing bath. The effluents from the gasifi- cation zone are directed into the radiation zone and into contact with the water containing bath, whereby combustion residues are retained by the bath. Synthesis gas can thereafter be removed from the radiation zone and further cooled in a convection chamber. Also disclosed is an apparatus for carrying out the process.
