Abstract
La presente invención se refiere a una protección térmica para estator (6) para una turbina de gas (1), que en estado montado presenta una trayectoria de gas caliente (9) del lado exterior adyacente a la turbina de gas (1), un lado interior (12) opuesto al lado exterior (11), varias nervaduras (13) formada en el interior (12), que en estado montado se extienden axialmente en relación a un eje de rotación (8) de un rotor (3) de la turbina de gas (1) y en la dirección periférica están separados, cuando menos una placa deflectora (14) montada en el lado interior (12), la cual se apoya sobre las nervaduras (13), cuando menos una ranura (16), que está formada en el lado frontal (15) que colinda en la dirección periférica con una protección térmica para estator (6), y en la cual puede introducirse cuando menos un elemento hermético (18), y varias perforaciones (19) que con un extremo desembocan en el lado interior (12) y con el otro extremo desembocan en el lado frontal (15) de la ranura (16) en dirección hacia el lado exterior (11) y están separadas entre si en dirección axial.
