Abstract (en)
[origin: EP1739194A1] Operating a melting furnace by supplying charge material, fuel and an oxidizing agent to a melting zone comprises injecting the oxidizing agent through peripheral ultrasonic injectors in supersonic pulses and adjusting the on/off ratio of the injectors and the number of injectors in use as a function of a predetermined or continuously determined oxidizing agent supply so that the supply is continuously maintained and a flow pattern that uniformly covers the melting zone is produced.
