PROCESS FOR GASIFYING FINELY GRAINED SOLID FUELS
A process of gasifying fine-grained solid fuels for the production of a product gas that contains hydrogen, carbon oxides and methane comprises a treatment with steam, oxygen and/or carbon dioxide in two interconnected gasifying stages under a pressure in the range from 2 to 150 bars and at temperat...

| description | A process of gasifying fine-grained solid fuels for the production of a product gas that contains hydrogen, carbon oxides and methane comprises a treatment with steam, oxygen and/or carbon dioxide in two interconnected gasifying stages under a pressure in the range from 2 to 150 bars and at temperatures of 500 DEG to 1500 DEG C. In the first gasifying stage, the fuel is gasified in a circulating fluidized bed by a treatment with gasifying stage. The residual solids which become available in the first gasifying stage are fed to the second gasifying stage and are virtually completely gasified therein, except for residual ash, by a treatment with a gasifying agent which includes oxygen. At least one-half of the product gas from the second gasifying stage is fed to the first gasifying stage and used as fluidizing fluid therein. |
