661,148. Gasifying powdered fuel. BADISCHE ANILIN- & SODA-FABRIK. Oct. 11, 1949 [Jan. 19, 1949], No. 26055/49. Classes 55 (i) and 55 (ii). In a process for the continuous production of fuel gas, particularly synthesis gas, granular or pulverulent fuel is gasified exothermically in one or more chambers a in which it is introduced tangentially, preferably with part of the oxygen-containing gasifying agent which also includes steam or carbon dioxide, the rest entering by an inlet d. Molten clinker runs into the sump i of an endothermically operated producer b into which the gases pass through a central outlet e and containing lump fuel, e.g. coal, briquettes, or low temperature distillation coke which may be charged from a communicating retort shaft. Small amounts of steam or other gasifying agents may be introduced through inlets f to regulate the temperature of the final gas composition. In an example, 7.5 metric tons of dry brown coal dust are gasified by 3850 cub. metres of oxygen and 3.7 metric tons of steam per hour and the gas at about 1700‹ C. passes into a charge of 3 metric tons per hour of mineral coal when in the other producer. 20,000 cub. metres of gas are obtained containing 54.5 per cent CO, 38.4 per cent H 2 , 5.7 per cent CO 2 , 1.4 per cent N 2 .
