Abstract

Apparatus for introducing solid fuels into a pressure gasification reactor comprising at least one conveyor worm turnable in a housing for conveying finely divided fuel, optionally mixed with a binder, and compacting the fuel into a gas-tight plug which is discharged through a discharge opening leading to the pressure gasification reactor. The discharge opening is provided with a closure member and the housing has an outlet opening also provided with a closure member near the discharge opening. The outlet opening is open to the ambient atmosphere. The closure members of the discharge opening and the outlet opening are alternatively actuatable such that when one is open the other is closed.
