In this apparatus, the burner of the gasification reactor is supplied with fuel via a proportioning vessel (1) which is associated with at least two lock vessels (2; 3), which are alternately filled with fuel while unpressurised and subsequently pressurised with suitable gas and then emptied into the proportioning vessel (1). The invention here provides that, in the lock vessels (2; 3) a pipe (4) is located which serves for the supply and discharge of gas and which consists sectionally of a porous material (6) and extends from the upper end of the lock vessels (2; 3) up to the vicinity of the outlet. For pressurising the lock vessel filled with fuel at the time, the same gas is used which is released when the lock vessel emptied at the time is let down. <IMAGE> |
