GASIFICATION OF COAL
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 combust...

| description | 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, the radiation zone have disposed at the bottom thereof and in fluid communication with the radiation zone a water containing bath. The radiation zone is cylindrical or conical, widens by 0 to 15 degrees towards the bottom, is made in a finned wall construction with a relation of height to diameter of |
