Abstract

La invención es concerniente con una turbina de gas que tiene una cámara de combustión secundaria (1) y una primera hilera de álabes de guía (2) de una turbina de baja presión, dispuesta directamente corriente abajo de la misma, en donde la delimitación exterior radial de la cámara de combustión secundaria (1) es formada por al menos un segmento de pared externo (4), que es sujetado a por lo menos un elemento de portador (5) dispuesto radialmente sobre el exterior, en donde la trayectoria de flujo de los gases calientes (3) es delimitada radialmente sobre el exterior con una plataforma externa (6) en la región de la hilera de álabes de guía (2) que es sujetada por lo menos indirectamente a por lo menos un portador de álabe de guía (8) y en donde hay una cavidad en forma de separación (9) que corre sustancialmente de manera radial y que tiene un ancho (B) en la región de entrada en la dirección axial en el intervalo de 1-25 mm, entre el segmento de pared (4) y la plataforma externa (6). La turbina de gas de acuerdo con la invención esta en particular caracterizada en que por lo menos un elemento de estribo es dispuesto en la región de entrada, que reduce el ancho citado (B) por al menos 10% en por lo menos un estribo (28) que corre sustancialmente de manera perpendicular a la dirección de flujo (11) del gas caliente en la cavidad (9).
