Abstract (en)

[origin: DE19739443A1] A device for producing sponge iron from iron oxide lumps consists of a reduction shaft in which a hot dust laden reducing gas is delivered. Said gas is produced in a gas generator by means of partial oxidation of solid carbon carriers and passes into the lower end of the reduction zone via lateral reduction gas inlets. The iron oxide lumps are fed to the upper area of the reduction shaft and are radially fed as sponge iron to the lower end of said reduction shaft via delivery organs (3). An additional delivery organ for sponge iron is provided within the middle area of the reduction shaft. The additional delivery organ is situated downstream from the surfaces in the reduction shaft base (2), said surfaces being configured between the inner ends of the delivery organ. In addition, a guiding device (6) is arranged between each of the two delivery organs and projects upwards above said organs in such a way that the sponge iron which is falling downwards is guided laterally to the delivery organs and radially to the additional delivery opening. Feed spirals are preferably used as delivery organs. One advantage of the guiding device is that it has an upper edge which runs in a diagonal manner from the additional delivery opening end up to the reduction shaft inner wall and it can be effectively enlarged downward and radially outwards to the width of the facing space between the delivery organs.
