ABSTRACT:
Particulate iron ore is reduced to sponge iron in a vertical shaft reduction reactor by forcing the ore upwardly in a moving bed counter-current to a descending stream of hot reducing gas produced by the gasification of coal in a gasifier, for example, a melter-gasifier, containing a molten iron bath and producing a hot dust-laden gas. The product sponge iron may be used as a feed material for the molten bath in the gasifier. The reactor is equipped with a gas outlet plenum containing a renewable body of ore to minimize clogging at the gas outlet.
