Abstract:
An apparatus for introducing and distributing solid fuel and a charge including a metal oxide, to a shaft furnace having a rectangular interior cross-section for the production of molten metal from said metal oxide, said apparatus comprising:a fuel distributor for distributing solid fuel into said furnace; a charge distributor disposed on opposite sides of said fuel distributor for distributing charge into the furnace; said fuel distributor distributing solid fuel into said furnace in a central region thereof to form a longitudinal, central column of solid fuel in said furnace; each said charge distributor including a respective tube journaled for movement in two planes perpendicular to one another, one longitudinally of the furnace, the other crosswise to the furnace, for distributing the charge on opposite sides of the solid fuel to form longitudinal columns of said charge on opposite sides of the central column of solid fuel thereby to maximize exchange of heat between ascending hot gas and said charge within said interior cross-section of said shaft furnace.
