Abstract

Particulate molten iron is reduced in a shaft furnace 10 by gaseous reduction to form hot metallised iron particulates, and these are melted in a melter-gasifier vessel 30 into which solid fuel e.g. coal and oxygen are injected (inlet 40). The hot off-gases in the vessel 30 are recirculated to the shaft furnace 10, via 60, 69, to reduce the particular iron oxide therein. The hot off-gases may be cooled, by use of liquid water sprayed in at 55, to a temperature suitable for use in reduction.
