ABSTRACT:
A method for modifying existing direct reduction processes and retrofitting existing direct reduction facilities so as to increase the capacity of the facilities without the need for increasing the capacity of external reformers associated with the existing facilities comprises mixing preheated air with the reformed reducing gas produced in the external reformers and containing said mixture with excess natural gas in a reduction-reaction zone of the direct reduction reactor.
