<p>A method for producing a hot CO- and H2-containing reducing gas utilized for the reduction of lumpy metal ore, in particular iron ore, which comprises forming the reducing gas in a gasification zone by the gasification of carbon carriers, in particular coal, taking place in the presence of a supply of oxygen and subsequently cooling the reducing gas down to a reducing-gas temperature favorable to the reduction process, wherein H2O and/or CO2 is added to a reducing gas which has been subjectged to a cooling operation that does not effect an addition of H2O/CO2 in order to prevent the Boudouard and heterogeneous water-gas reaction and a resultant heating of the reducing gas, wherein the reducing gas is converted to a reducing gas that is thermodynamically more stable at the reducing-gas temperature.</p> |
