Abstract

Det beskrives en fremgangsmåte for injisering av oksygen inn i en smelte lokalisert i en metallurgisk ovn med en oppvarmet ovnsatmosfære der oksygen og brennstoff injiseres i en eller flere dyser med passasjer med konvergerende-divergerende konfigurasjon under strupte strømningsbetingelser for derved å gi én eller flere supersoniske stråler som slippes ut fra passasjene. Brennstoff injiseres i indre omkretslokasjoner i passasjene for å gi strålene som slippes ut en struktur som har et ytre omkretsornråde inneholdende en blanding av brennstoff og oksygen og et sentralt område inneholdende i det vesentlige oksygen. En slik strukturert stråle interagerer ved utslipp med ovnsatmosfæren og skaper en ytre skjære-blandesone der det ytre omkretssjiktet blandes med den oppvarmede ovnsatmosfæren og selvantennes for å gi en flammeomhylling som omgir den supersoniske oksygenstrålen. Strålen av oksygen og flammeomhylling kan så rettes mot en smelte som inneholdes i den metallurgiske ovnen for injeksjon av oksygen i smelten.
