Abstract

Bei einer axialdurchströmten Gasturbine, im wesentlichen bestehend aus einer mehrstufigen Turbine (1), welche einen auf einer gemeinsamen Welle (13) angeordneten Verdichter (10) antreibt, bei welcher der zwischen der Turbine (1) und dem Verdichter (10) liegende Wellenteil eine Trommel (14) ist, die von einer Trommelabdeckung (15) unter Bildung eines Ringkanals (20) umgeben ist, wobei im Ringkanal (20) eine gegen die Trommelabdeckung (15) dichtende Labyrinthdichtung (21) angeordnet ist, und die Trommelabdeckung (15) zusammen mit der Stirnseite (18) des Turbinenrotors (3) einen radial verlaufenden Radseitenraum (19) begrenzt, bei der seperate Leitungen (22) zur Führung der Turbinenrotorkühlluft vom Verdichter (10) zur Stirnseite (18) des Turbinenrotors (3) angeordnet sind und die Verbindung zwischen diesen Leitungen (22) und dem Radseitenraum (19) jeweils über mindestens eine Dralldüse (23) erfolgt, bei der Kühleinrichtungen (24) für den Turbinenrotor (3) und seine Laufschaufelkränze vorhanden sind und die gesamte rotorseitige Kühlluft für die Turbine (1) dem Verdichter (10) im Bereich des Verdichteraustritts entnommen wird, ist im Bereich des Trommellabyrinths (21) mindestens eine Absaugvorrichtung (25) für die Leckageluft und einen Teil der Kühlluft angeordnet. Die Absaugvorrichtung (25) steht mit den Kühleinrichtungen der hinteren Turbinenstufen in Verbindung.
