COMBINED MELTING GASIFIER AND A DIRECT REDUCTION SHAFT FURNACE

摘要

In a combination of a melting gasifier and a direct reduction shaft furnace disposed 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.
