<p>The present invention relates to an apparatus for manufacturing molten irons byinjecting fine carbonaceous materials into a melter-gasifier and a method formanufacturing molten irons using the same. The method for manufacturing moltenirons according to the present invention includes steps of reducing mixtures containingiron ores in a reduction reactor and converting the mixtures containing ironores into reduced materials, preparing lumped carbonaceous materials containingvolatile matters as a heating source for melting the reduced materials, chargingthe lumped carbonaceous materials into a dome-shaped upper portion of a melter-gasifierand forming a coal packed bed, preparing fine carbonaceous materials containingvolatile matters as a heating source for melting the reduced materials, injectingoxygen and the fine carbonaceous materials into the coal packed bed through atuyere installed in the melter-gasifier, charging the reduced materials intothe melter-gasifier connected to the reduct ion reactor and manufacturing moltenirons, and supplying reducing gas in the melter-gasifier made from volatile matterscontained both in the lumped carbonaceous materials and the fine carbonaceous materialsto the reduction reactor.</p> |
