Description

Die Erfindung betrifft eine Brennkammer für Gasturbinen mit mehreren in selbständigen rohrförmigen Haltern angeordneten Brennern, die während des Betriebs auswechselbar sind.The invention relates to a combustion chamber for gas turbines with several in independent tubular holders arranged burners, which during operation are interchangeable.

Brennkammern der oben umrissenen Art sind bereits bekannt. Diese bekannten Brennkammern haben indessen wesentliche Nachteile. So ist bei einer der bekannten Brennkammern eine Einrichtung zur Einspritzung zusätzlicher Strömungsmittel zur Schuberhöhung von Strahltriebwerken mittels mehrerer in den Strömungskanal zwischen Verdichter und Brennkammer hineinragender, mit dem Strömungsmittel beaufschlagter Bauteile vorgesehen, wobei jedes Bauteil mittels eines durch den Einspritzdruck des Strömungsmittels beaufschlagten Kolbens in den Strömungskanal ausschiebbar und mittels des in dem Strömungskanal herrschenden Überdruckes nach Absinken des Einspritzdruckes in die Ausgangsstellung zurückbewegbar und in einem der äußeren oder inneren Gehäusewand befestigten Zylinder angeordnet ist. Hierbei wird allein durch den überdruck in der Brennkammer, entgegen dem druckfederbelasteten Ventil, die Öffnung zur Atmosphäre verschlossen. Ein Auswechseln des Bauteils ist jedoch nur unter sehr schwierigen Bedingungen, wenn überhaupt, möglich, wobei die ganze Anordnung kompliziert gebaut und dementsprechend schwierig zu warten ist.Combustion chambers of the type outlined above are already known. These well-known Combustion chambers, however, have significant disadvantages. So is with one of the well-known Combustion chambers a device for injecting additional fluid for Thrust increase of jet engines by means of several in the flow channel between Compressor and combustion chamber protruding, exposed to the fluid Components provided, each component by means of one by the injection pressure the piston acted upon by the fluid can be pushed out into the flow channel and by means of the overpressure prevailing in the flow channel after the injection pressure has dropped can be moved back into the starting position and in one of the outer or inner housing walls attached cylinder is arranged. The overpressure in the combustion chamber, against the pressure spring-loaded valve, the opening to the atmosphere locked. Replacing the component is very difficult, however Conditions, if any, possible, with the whole arrangement intricately built and therefore difficult to maintain.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Brennkammer für Gasturbinen zu schaffen, bei welcher der Brenner auch im Betrieb auf einfache Weise auswechselbar ist, wobei die Anordnung technisch nicht aufwendig und leicht zu warten ist.The present invention is based on the object of a combustion chamber to create for gas turbines, in which the burner also in operation on simple Way is exchangeable, the arrangement being technically not complex and easy to wait is.

Die Brennkammer für Gasturbinen ist dadurch gekennzeichnet, daß jeder der Halter mit einer durch eine Schließkraft, z. B. durch ein Gewicht belasteten Rückschlagklappe versehen ist, wobei in dem Mantel eines jeden Brenners ein Kolben derart angeordnet ist, daß er beim Herausnehmen des Brenners so lange in dem Halter dichtend gleitet, bis die Rückschlagklappe geschlossen ist.The combustor for gas turbines is characterized in that each the holder with a by a closing force, for. B. burdened by a weight Check valve is provided, with a piston in the jacket of each burner is arranged so that it is so long when removing the burner in the holder slides sealingly until the non-return valve is closed.

Durch diese erfindungsgemäße Ausbildung der Brennkammer ist gewährleistet, daß jeder einzelne Brenner während des Betriebs herausnehmbar ist, ohne daß nach dem Ausbau des Brenners durch die entstehende Öffnung der brennende Brennstoff herausschlagen kann. Eine solche Herausnahme und ein Einbau des Brenners kann auch während des Betriebs selbst bei hohem Druck vorgenommen werden.This inventive design of the combustion chamber ensures that that each individual burner can be removed during operation without having to When removing the burner, knock out the burning fuel through the resulting opening can. Such removal and installation of the burner can also be done during the Operation can be made even at high pressure.

Weitere Vorteile der erfindungsgemäßen Brennkammer ergeben sich aus der nachfolgenden Erläuterung der Erfindung an Hand der Zeichnung.Further advantages of the combustion chamber according to the invention result from the following explanation of the invention with reference to the drawing.

Der Halter 1 des Brenners 7, der in dem Raum 2 der Brennkammer 3 mündet, ist mit einer automatisch wirkenden Rückschlagklappe 4 versehen, die um den Zapfen 5 schwenkbar ist. Diese Klappe 4 ist mit einem Gegengewicht 6 verbunden, unter dessen Wirkung die Klappe an den Körper des Brenners 7 gedrückt wird. Dabei ist der Brenner 7 als dichtender Kolben 10 ausgebildet, welcher mit Dichtungsringen versehen ist. Beim Herausnehmen des Brenners 7 setzt sich die,' Rückschlägklappe 4 auf den im Halter 1 gebildeten Sitz 9 auf, bevor sich der dichtende Kolben 10 aus dem Halter 1 herausschiebt.The holder 1 of the burner 7, which opens into the space 2 of the combustion chamber 3, is provided with an automatically acting non-return valve 4 around the pin 5 is pivotable. This flap 4 is connected to a counterweight 6, under which Effect, the flap is pressed against the body of the burner 7. Here is the burner 7 designed as a sealing piston 10 which is provided with sealing rings. When the burner 7 is removed, the 'non-return valve 4' sits on the im Holder 1 formed seat 9 before the sealing piston 10 is out of the holder 1 pushes out.
