MELTING PROCESS USING THE COMBUSTION OF LIQUID AND GASEOUS FUELS

摘要

The invention relates to a process for melting a charge by means of oxy-fuel combustion burners in a furnace (1) that includes at least one upstream flue gas outlet (3), in which furnace, in the charge melting zone: the burners (41-44) placed close to the upstream flue gas outlet burn a liquid fuel; and at least one of the burners (51-54) placed far from the upstream flue gas outlet burns a gaseous fuel.
