Abstract

El texto describe un segmento de acumulacion termica para la separacion local de un canal (K) de flujo dentro de una turbina, en particular una instalacion de turbina de gas, con relacion a una caja (2) del estator que rodea radial al canal (K) de flujo, con dos contornos (17, 18) de encajadura axialmente opuestos que en cada caso intervienen en dos componentes (4, 4') axialmente adyacentes a lo largo del canal (K) de flujo. La invencion se caracteriza porque un primero (17) de los dos contornos de encajadura tiene una cavidad (27) de orientacion radial, con una superficie (28) de contorno en la que se puede encajar radial un espiga (31) de fijacion que tiene un contorno (34) externo que se adapta a la superficie de contorno de la cavidad mediante la accion de fuerza por parte de un componente (4) adyacente al primer contorno (17) de encajadura, y el primer contorno (17) de encajadura tiene una seccion (23) de collar con una superficie de collar radial superior (24) e inferior (25), y esta seccion de collar puede formar una union encajada dentro de un contorno (26) de recepcion de contorno inverso del componente (4) axialmente adyacente mediante una fuerza de ancajadura que actua entre la espiga (31) de fijacion y la superficie (28) de contorno conica. (Fig. 1b).
