Title
(DE) BRENNER FÜR GASTURBINENTRIEBWERKE
(EN) GAS TURBINE COMBUSTOR
(FR) PROPULSEURS POUR TURBINES A GAZ
Abstract
(DE) Der Brenner soll am Kopfende einer Brennkammer mindestens eine Brennstoffdüse (9) und mindestens eine für die Zufuhr von Verbrennungsluft lastabhängig regulierbare Dralleinrichtung (7) mit zwischen radialen Wandteilen eines düsenkoaxialen Ringkörpers radialen/tangentialen Durchbrüchen (3) aufweisen, in die über dem Umfang verteilte Finger (5) einer gegenüber dem Ringkörper verstellbaren Hülse eingreifen, dabei soll die Hülse (4) mit den Fingern axial verschiebbar am äußeren Umfang des Ringkörpers angeordnet sein und die Finger sollen jeweils parallel zu axial beabstandeten Wänden der Durchbrüche gegen die zentrale Brennerachse abgewinkelt sein und sich über die gesamte Durchbruchlänge erstrecken. Gegebenenfalls in Kombination mit mindestens einer stationären Dralleinrichtung (8) soll eine an Schadstoffen arme Verbrennung erzielt werden.
(EN) The combustor proposed has, located at the head end of the combustion chamber, at least one fuel-inlet nozzle (9) and at least one swirl device (7), which can be regulated as a function of the load, for the supply of combustion air, the swirl device having radial/tangential apertures (3) between the radial walls of an annular body disposed coaxially with the nozzle. Extending into these apertures are fingers (5) located round the end of a sleeve (4) which can be moved with respect to the annular body. The sleeve with its fingers is disposed so that it can be displaced longitudinally across the outside surface of the annular body, the fingers being angled with respect to the central combustor axis so that they are parallel to the longitudinally separated walls of the apertures and extending over the whole length of the apertures. The combustor proposed, optionally combined with at least one stationary swirl device (8), gives combustion with low polluant levels.
(FR) Un brûleur doit avoir à l'extrémité de tête d'une chambre de combustion au moins un gicleur (9) de combustible et au moins un dispositif à tourbillon (7) réglable en fonction de la charge pour assurer l'amenée d'air de combustion, ainsi que des passages (3) radiaux/tangentiels entre des parties radiales de la paroi d'un corps annulaire coaxial par rapport au gicleur. Des doigts (5) répartis autour de la circonférence d'un manchon (4) qui peut être déplacé par rapport au corps annulaire entrent dans lesdit passages. Le manchon avec les doigts est monté axialement mobile sur la circonférence extérieure du corps annulaire et les doigts, agencés parallèlement à des parois axialement espacées des passages, sont inclinés par rapport à l'axe central du brûleur et s'étendent sur toute la longueur des passages. On obtient ainsi une combustion émettant peu de substances toxiques, éventuellement en association avec au moins un dispositif stationnaire à tourbillon (8).
