APPARATUS AND METHOD FOR MANUFACTURING REDUCED IRON

摘要

The present invention relates to an apparatus and method for manufacturing reduced iron. The method for manufacturing reduced iron comprises: i) a step of drying ore in an ore dryer; (ii) a step of supplying the dried ore to one or more reducing furnaces; iii) a step of reducing the ore in the one or more reducing furnaces so as to produce reduced iron; iv) a step of releasing exhaust gas produced during the ore-reducing step from the reducing furnaces; v) a step of branching the exhaust gas to supply ore-conveying gas; and vi) a step of performing heat exchange between the exhaust gas and the ore-conveying gas to deliver the sensible heat of the exhaust gas to the ore-conveying gas. In the step of supplying the dried ore to the one or more reducing furnaces, ore dried by the ore-conveying gas is supplied to the one or more reducing furnaces.
