Abstract

A device for feeding granular and dust coal to a coal-gasifying reactor which operates under a pressure of 5 to 150 bars. A stationary housing is connected to the coal inlet of the reactor and a lock chamber member is rotatedly mounted therein. The lock chamber member is movable between coal-receiving position and a coal-discharging position. The lock chamber member has at least one chamber which is open only at one end and contains a displacing device which extends approximately to the entrance of the chamber. The displacing device substantially prevents an ingress of product gas into the chamber when in the discharge position.
