Abstract
In the case of an arrangement comprising a gasifier and a direct reduction shaft furnace positioned above it and which is connected to the gasifier by a connecting shaft, the direct introduction of the reduction gas obtained in the gasifier, even in the case of a high dust proportion, is made possible in that the sponge iron particles are discharged through several radially positioned screw conveyors and the reduction gas is fed to an annular zone formed above the screw conveyors.
