718,657. Gasifying solid fuel. KOPPERS GES., H. July 7, 1952 [July 13, 1951], No. 17063/52. Class 55 (1) In a process for the continuous generation of combustible gas from finely divided solid fuel, the fuel is suspended in oxygen and is injected from nozzles 13 into conical reaction chambers 9 and 10 which open tangentially into the upper part of a cylindrical vessel 1 provided with a cooling water jacket. The fuel is ignited near each nozzle and forms an exothermic reaction zone 16. Steam or carbon dioxide is admitted from an annu'ar nozzle 15 to form an envelope around each zone 16. The reactants travel in a straight path through chambers 9 and 10 and into vessel 1, the exothermic reaction being substantially complete before they impinge on the, vessel wall at 17. Due to their inertia and the effect of centrifugal force, the velocity of the highly heated, unburnt particles is 'greatly reduced as the reactants pass around the wall of the vessel, the resulting relative movement between the steam or carbon dioxide and the particles facilitating the endothermic reaction. The generated gas and the fuel residue discharge through water cooled outlets 6 and 8-respectively.
