Claims (5)

1. Drallbrenner, mit einem ein Brennstoff-Luftgemisch zuführenden Brennerrohr beziehungsweise einem Brennerkopf, in dessen Ausströmöffnung ein die Gemischströmung verdrallender Leitschaufelkranz eingebaut ist, dadurch gekennzeichnet, daß die Drallwirkung des Leitschaufelkranzes (10, 28) zum Zweck der Flammenstabilisierung durch Verstellen von Leitschaufeln (16, 18, 32) variierbar ist.1. Swirl burner, with a burner tube or a burner head supplying a fuel-air mixture, into the outflow opening of which a guide vane ring which swirls the mixture flow is installed, characterized in that the swirl effect of the guide vane ring ( 10 , 28 ) for the purpose of flame stabilization by adjusting guide vanes ( 16 , 18 , 32 ) is variable. 2. Drallbrenner nach Anspruch 1, dadurch gekennzeichnet, daß der Leitschaufelkranz (10) aus zwei Gruppen (12, 14) von Leitschaufeln (16, 18) mit unterschiedlichem Anstellwinkel gebildet ist und jede Leitschaufelgruppe (12, 14) ein eigenes Tragteil (20, 22) hat, von denen mindestens eines beweglich gelagert und steuerbar ist.2. Swirl burner according to claim 1, characterized in that the guide vane ring ( 10 ) is formed from two groups ( 12 , 14 ) of guide vanes ( 16 , 18 ) with different angles of attack and each guide vane group ( 12 , 14 ) has its own supporting part ( 20 , 22 ), of which at least one is movably supported and controllable. 3. Drallbrenner nach Anspruch 2, dadurch gekennzeichnet, daß das Tragteil (20) der einen Leitschaufelgruppe (12) ein in das Brennerrohr beziehungsweise in einen Brennerkopf einsetzbarer, die Ausströmöffnung für das Brennstoff- Luftgemisch umschließender Ringkörper ist, von dem die Leitschaufeln (16) nach innen abstehen. 3. Swirl burner according to claim 2, characterized in that the supporting part ( 20 ) of one guide vane group ( 12 ) is an insertable in the burner tube or in a burner head, the outflow opening for the fuel-air mixture enclosing annular body, of which the guide vanes ( 16 ) stick out inside. 4. Drallbrenner nach Anspruch 2, dadurch gekennzeichnet, daß das Tragteil (22) der einen Leitschaufelgruppe (14) ein zentral im Brennerrohr beziehungsweise Brennerkopf vorzugsweise beweglich gelagerter und steuerbarer Nabenkörper ist, von dem die Leitschaufeln (18) nach außen abstehen.4. Swirl burner according to claim 2, characterized in that the supporting part ( 22 ) of the guide vane group ( 14 ) is a centrally in the burner tube or burner head preferably movably mounted and controllable hub body, from which the guide vanes ( 18 ) protrude outwards. 5. Drallbrenner nach Anspruch 1, mit einem Leitschaufelkranz, der durch entsprechende Krümmung der Leitschaufeln eine radial Drallkomponente erzeugt, dadurch gekennzeichnet, daß der Leitschaufelkranz (28) als ganzes derart axial verstellbar gelagert und steuerbar ist, daß seine die radialen Austrittsöffnungen (36) begrenzenden Leitschaufelkanten (38) mehr oder weniger weit über den Mündungsrand (40) des Brennerrohres (26) beziehungsweise Brennerkopfes hervortreten.5. Swirl burner according to claim 1, with a guide vane ring which generates a radial swirl component by appropriate curvature of the guide vanes, characterized in that the guide vane ring ( 28 ) as a whole is axially adjustable and controllable in such a way that it delimits the radial outlet openings ( 36 ) Guide vane edges ( 38 ) protrude more or less far beyond the mouth edge ( 40 ) of the burner tube ( 26 ) or burner head.
