METHOD FOR OPERATING A METALLURGICAL FURNACE

A method for operating a metallurgical furnace and a simplified way of providing synthesis gas for a metallurgical furnace, includes the following stepsperforming a combustion process outside the metallurgical furnace by combusting a carbon-containing material with an oxygen-rich gas to produce an offgas, which offgas is a CO2 containing gas;and combining the offgas, while having an elevated combustion-induced temperature due to the combustion process, with a hydrocarbon-containing fuel gas to obtain a first gas mixture having a temperature above a reforming temperature necessary for a reforming process, preferably a dry reforming process;the first gas mixture undergoing the reforming process, thereby producing a synthesis gas containing CO and H2, the reforming process being performed non-catalytically; andfeeding the synthesis gas into the metallurgical furnace.
