Abstract

1,178,287. Blast furnace process. BAILEY INVENTIONS, Inc. Aug.16, 1967, No.37816/67. Heading C7D. [Also in Division F4] In a blast furnace process for extracting iron the solid carbonaceous fuel is encased in a multiplicity of individual gas-impervious containers made of metal having a melting point greater than 2200‹ C., so that the fuel remains out of contact with oxidizing agents until it reaches the hot reduction zone of the furnace. By this means the latent heat of the waste gases may be recovered in the furnace by combusting them with secondary air admitted to the upper preheating zone of the furnace. The containers may be made of iron, steel, or a metal which alloys with the iron produced. In the particular embodiment described and illustrated, the additional heat recovered by the invention is used in part to preheat both the primary and secondary air supplies by means of a double air heater surmounting the furnace.
