摘要

The metering device (10) has solid fuel container (20) and a conveying element (30) for conveying solid fuel from the container to a feed device (60). The feed device supplies solid fuel to a combustion chamber of a combustion plant. The conveying element has pipe (31) which is vertically and rotatably mounted within the container. A wall (32) in the lower region of the pipe has a metering orifice (40). A driving element (50) for the solid fuel is arranged in the wall at a side edge (41) of the metering orifice.
