Claim Text:
1. An injector apparatus ( 1 ) for the pyrometallurgical treatment of metals, molten metals and/or slags in a metallurgical unit or melting vessel, said apparatus comprising an injector device ( 2 , 3 ) for producing a high-velocity gas jet ( 5 ) from an oxygen gas jet ( 6 ) and an ignited combustible gas/air mixture jet ( 7 ), in which the injector device ( 2 , 3 ) comprises a de Laval nozzle element ( 8 ) disposed in a nozzle head part ( 41 ) for producing the oxygen gas jet ( 6 ), and in which the combustible gas/air mixture ( 7 ) can be mixed by means of a mixing element ( 9 ) for mixing combustible gas ( 32 ) and air ( 36 ), characterized in that the de Laval nozzle element ( 8 ) and the mixing element ( 9 ) are arranged jointly within and/or on the nozzle head part ( 41 ) along the center longitudinal axis ( 13 ) of the injector device ( 2 , 3 ), detachably from one another and one behind the other, so that between the nozzle head ( 41 ) and the de Laval nozzle element ( 8 ), an annular space ( 43 ) is formed into which a combustible gas channel ( 34 ) and an air channel ( 38 ) of the mixing element ( 9 ) open.
