“Apparatus And Method For Manufacturing Molten Iron”
Abstract: The present invention relates to an apparatus and method for manufacturing molten iron while reusing an offgas of the packed bed reduction reactor and improving energy efficiency. A method for manufacturing molten iron includes i) charging fine ore into at least one fluidized-bed reduction reactor and manufacturing reduced iron; ii) compacting the reduced iron and manufacturing compacted reduced iron; iii) charging the reduced iron into a packed bed reduction reactor and reducing the reduced iron again; iv) charging the re-reduced iron into a melter-gasifier; v) charging lumped carbonaceous materials into the melter- gasifier and forming a coal packed bed in the melter-gasifier; vi) injecting oxygen into the melter-gasifier and combusting the coal packed bed, thereby melting the re-reduced iron and manufacturing molten iron; and vii) supplying an offgas that is discharged from the packed bed reduction reactor to the fluidized-bed reduction reactor.
