PRODUKSI ZAT BESI YANG MENYUSUT LANGSUNG DENGAN PEMAKAIAN BAHAN BAKAR SERTA PENGELUARAN MONOKSIDA KARBON YANG BERKURANG

摘要

A system for producing direct reduced iron wherein iron oxide material and carbonaceous material is passed successively through an oxidizing zone and a reducing zone of a furnace, each zone fired by oxy-fuel combustion, enabling a reduction in the amount of fuel needed to process the material while generating sufficient carbon monoxide to effect the reduction and ensuring that little or no carbon monoxide is emitted from the furnace.
