METHOD AND A SYSTEM FOR PRODUCING DIRECT REDUCED IRON USING COAL-DERIVED GAS

摘要

ABSTRACT OF THE DISCLOSURE In a method of producing direct reduced iron with use of a coal-derived gas, coal is heated to lower the moisture thereof, and the moisture-lowered coal is gasified in a coal gasification furnace to produce a coal-derived gas containing a reducing gas. The reducing gas is then utilized to reduce iron ore in an iron ore reducing furnace. With use of an exhaust gas from the iron ore reducing furnace the coal is heated in the step of heating coal.
