Abstract (en)
[origin: EP0299231A1] The equipment for charging a fusion gasifier (2) with gasifying agents and iron sponge discharged from a direct-reduction shaft furnace (1) arranged above the fusion gasifier consists of inlets and outlets in the lower part of the shaft furnace, connecting lines (4) extending in the upper region of the gasifier symmetrically to the longitudinal axis of the shaft furnace and/or of the gasifier in the form of drop pipes between the shaft furnace and the gasifier and of iron sponge discharge devices (7), such as screw conveyors or the like, aligned radially relative to this longitudinal axis. The connecting lines here lead at least approximately vertically into the lowest, essentially horizontally extending bottom region of the shaft furnace. The discharge devices are located at the inlets (9) of the fusion gasifier downstream of the connecting lines in the discharge direction, and the inlet (3) for the gasifying agent is located in the longitudinal axis of the fusion gasifier directly next to the inlets for the iron sponge. Preferably, the inlets for the iron sponge and gasifying agent are located within a domed top (5) of the fusion gasifier. <IMAGE>
