Theoretical and experimental study of supersonic oxygen jets. Industrial application in EAF
Oxygen consumption in the EAF continues to increase, partly due to the development of various technologies based on supersonic lancing. This paper discusses the characteristics of supersonic jets and their industrial implementation. Based on fluid mechanics, numeric modelling and laboratory measurements, physical parameters which can act on the quality of the jet are reviewed. Alarc Jet supersonic injection technology has been designed to provide, in addition to high-standard burners and postcombustion tools, the best global efficiency of oxygen in the EAF. Application to the 160-t furnace of SAM Neuves-Maisons is described.
