Abstract:
A device for producing sponge iron from iron oxide lumps in a reduction shaft, using a hot dust laden reduction gas which is produced in a gas generator through partial oxidation of solid carbon carriers and is guided via lateral reduction gas inlets at the lower end of the reduction zone into the reduction shaft, in which device the iron oxide lumps are placed in the upper region of the reduction shaft and are delivered radially at the lower end of the shaft as sponge iron by delivery organs, and an additional delivery opening for the sponge iron is provided in the base of the reduction shaft in the central region of the reduction shaft below the area formed between the inner ends of the delivery organs wherein the delivery organs are provided to convey the sponge iron only radially outwards and wherein below the additional delivery opening, there is located a shaft with a diameter which tapers downwards, remains the same or widens, wherein the shaft is closed at the lower end, and wherein at least one further delivery organ for the sponge iron, acting radially, is disposed above the base of the shaft.
