Abstract

Die Erfindung bezieht sich auf einen Brennkammerkopf einer Gasturbine mit einer ein Dämpfungsvolumen (207) einschließenden Berandung, bestehend aus einer brennkammerabgewandten Berandung (206) sowie einer brennkammerseitigen Berandung (210), dadurch gekennzeichnet, dass die brennkammerseitige Berandung (210) in Form einer perforierten Wand (210) ausgebildet ist, dass im Randbereich der brennkammerseitigen Berandung (210) durch Ausnehmungen (203) in der Berandung (206) Kühlluft auf die brennkammerseitige Berandung (210) leitbar ist, dass diese Kühlluft, welche entlang der brennkammerseitigen Berandung (210) fließt, den Kühlluftstrom durch die perforierte Wand (210) in die Brennkammer (101) kreuzt, dabei von dieser durch Wände getrennt ist und sich nicht mit ihr mischt.
