Abstract

La invención se refiere a una turbina de gas (1) que comprende un rotor (2), que tiene dos hileras de álabes (5) con una pluralidad de álabes (6), y un blindaje térmico (7) de rotor, interpuesto, con una pluralidad de elementos de blindaje (12), y un estator (3), el cual tiene una hilera (8) de álabes de guía, con una pluralidad de álabes de guía (9) colocados axialmente entre las dos hileras de álabes de guía (5), adjuntas. Los álabes de guía (9) tienen una estructura de selladura (10) de estator radialmente sobre la parte interna. Los elementos de blindaje (12) tienen una estructura (13) de selladura del rotor radialmente sobre la parte externa, la estructura interactúa con la estructura (10) de selladura del estator para formar un sello axial (14). Además, entre dos álabes adjuntos (6) un sello (15) de álabe radial, y entre dos elementos de blindaje adjuntos (12), un sello de blindaje radial (16), están configurados, los cuales cada uno separan una trayectoria de gas (17) desde el rotor (2). Con el fin de incrementar la eficiencia, los elementos de blindaje (12) y los álabes (6) son acoplados uno al otro, tal que el sello (16) de blindaje radial realiza la transición sin interrupción hacia los sellos (15) de álabe radial de los dos álabes (6) axialmente adjuntos, de modo que es formado un sello radial continuo (21) desde un álabe (6) vía el elemento de blindaje (12) hacia el otro álabe (6).
