apparatus for producing direct reduced iron using a melter gasifier and two reduction reactors in the first reduction reactor iron ore is prereduced using a reducing gas from a melter gasifier this prereduced iron ore is fed into the melter gasifier to produce pig iron a secondary reducing gas comprising hydrogen and carbon monoxide is withdrawn from the first reduction reactor and is reacted with water to produce carbon dioxide which is subsequently removed to produce a tertiary reducing gas that is used in the second reduction reactor to produce direct reduced iron from iron ore application_number US 52929295 A description the invention is herein described as applied to direct reduction systems having moving bed reactors but it will be understood that it can be adapted to plants having fixed beds or fluidized bed reactors with reference to fig1 in a melter gasifier 10 prereduced iron ore 22 from a first reduction reactor 12 is melted by the reaction of coal 16 and oxygen 18 which produces heat for melting the iron ore and also reducing gas 14 comprising hydrogen and carbon monoxide the melted iron is removed from the melter gasifier as pig iron 20 the reducing gas 14 is fed to the first reduction reactor 12 to reduce iron ore 24 introduced at the upper part of reactor 12 and top gas 26 which comprises reductants like hydrogen and carbon monoxide as well as oxidants like water and carbon dioxide resulting from the reduction reactions of iron oxides a portion of the top gas 26 exiting.
