Claim:
A generator comprising (I) a double-chamber lock comprising two tapered or vertical chambers lined with ceramics or plastics, as a charging device, (II) at least one tubular shaft furnace comprising a water-cooled double jacket of steel, (III) a double-walled, water-cooled inlet nozzle of pure copper for a gasification mixture, arranged centrally in the tubular shaft furnace just above the base, and (IV) a dry dust-removing device, wherein the double-chamber lock (I) is adapted to open one of the chambers when the lower chamber of the double-chamber lock (I) is flushed with inert gas after each charging operation and opening operation, and the inlet nozzle (III) is configured as a mixing member for the constituents of the gasification mixture, the inlet nozzle is curved in a direction of flow of the gasification mixture and is characterised by a radius of curvature of the surface of the cylindrical portion of the nozzle which continuously becomes smaller to the outlet opening, and the direction of flow of the gases leaving the inlet nozzle is directed vertically upwards.
