The fuel is part-gasified in a reactor at 350 deg C-800 deg C under a pressure of 1-100 bar; producing coke, gas and steam. The fuel is preferably moved mechanically or pneumatically, mixing it into in a coking bed, cloud or conveyed stream at the operational temperature. Oxygen is added as air, air/steam mixture and/or as carbon dioxide, in quantities sufficient to maintain the operational temperature. Simultaneously, coke and gas/steam mixture are extracted from the reactor. Preferred Features: The temperature gradient in the gasification region is kept below 500 deg C by cyclic addition of oxygen over a large area, by the proportion of steam and carbon dioxide in oxygen or air supplied and by the intensity of mechanical and/or pneumatic mixing of the entrained fuel and coke. Before mixing-in the fuel, it is charged with liquid and/or gaseous wastes and/or pollutants. |
