Abstract
An apparatus for charging a melting gasifier (2) with gasification media and with sponge iron discharged from a direct reduction shaft furnace (1) arranged above the melting gasifier is described. This comprises inlets and outlets in the lower part of the shaft furnace, connecting lines (4) in the form of downcomers between the shaft furnace and the gasifier in the upper region of the latter, symmetrically to the longitudinal axis of the shaft furnace and/or the gasifier and discharge means (7) for the sponge iron, such as screw conveyors or the like aligned radially to said longitudinal axis. The connecting lines at least approximately vertically issue into the lowermost, substantially horizontal base region of the shaft furnace. The discharge means are arranged at the melting gasifier inlets (9) in the discharge direction behind the connecting lines and the gasification medium inlet (3) is located in the longitudinal axis of the melting gasifier immediately adjacent to the sponge iron inlets. The sponge iron and gasification medium inlets are preferably located within a melting gasifier dome (5).
