Abstract

Bei einer Gasturbine (10) leitet eine erste Mehrzahl von konzentrisch zur Drehachse in einer regulären Anordnung angeordneten Brennern (22a, b, c) jeweils durch einen zugehörigen Brennkammerauslass (11) Heissgas (12) in eine Turbine ein, an deren Eingang eine zweite Mehrzahl von Leitschaufeln (15; 15a, b, c, d) in einem Kranz um die Drehachse herum gleichmässig beabstandet angeordnet sind, wobei über den Umfang verteilt Kühlöffnungen vorgesehen sind, durch welche Kühlluft in den Heissgasstrom am Brennkammerauslass (11) eingedüst wird. Bei einer solchen Gasturbine wird eine Verbesserung der Strömungsverhältnisse im Heissgas, dadurch erreicht, dass die Kühlöffnungen in erste Kühlöffnungsgruppen (20a, b, c, d) und zweite Kühlöffnungsgruppen (21') aufgeteilt sind, dass die Anordnung der ersten Kühlöffnungsgruppen (20a, b, c, d) der Anordnung der Leitschaufeln (15; 15a, b, c, d) entspricht, und dass die Anordnung der zweiten Kühlöffnungsgruppen (21') der regulären Anordnung der Brenner (22a, b, c) entspricht.
