VERFAHREN ZUM ERZEUGEN EINES FÜR EINE REDUKTION VON METALLERZ DIENENDEN REDUKTIONSGASES
摘要:
In a process for producing a reduction gas containing hot CO and H2 for reducing lump ore, particularly iron ore, the reduction gas is formed by gasification of carbon containing materials, particularly coal, under the addition of oxygen in a gasification zone (8) and subsequently cooled to a reduction gas temperature conducive to the reduction process. To produce a reduction gas of greater thermodynamic stability, H2O and/or CO2 are added to eliminate the Boudouard and heterogeneous water gas reaction and the concomitant warming of the reduction gas.
