Abstract
An apparatus for manufacturing molten iron includes i) at least one fluidized-bed reduction reactor that reduces and plasticizes iron ore and converts the iron ore into reduced materials, ii) a melter-gasifier into which the reduced ore is charged and oxygen is injected, the melter-gasifier manufacturing molten iron, and iii) a reducing gas supply line that supplies a reducing gas discharged from the melter-gasifier to the fluidized-bed reduction reactor. The fluidized-bed reduction reactor includes a cyclone that is installed in the fluidized-bed reduction reactor to collect fine iron ore. A gas injector, which prevents the fine ore from adhering by injecting gas containing carbon, is connected to the cyclone.
