Title
(EN) STATOR AERODYNAMIC COMPONENTS WITH NOZZLES AND METHODS FOR CLEANING A TURBOMACHINE
(FR) COMPOSANTS AÉRODYNAMIQUES DE STATOR À BUSES ET PROCÉDÉS DE NETTOYAGE D'UNE TURBOMACHINE
Abstract
(EN)
A stator aerodynamic component (130, 250) is disclosed to be placed inside a flow path (500) of a working fluid of a turbomachine (1000); the component (130, 250) has one or more nozzles (135, 255) for ejecting a liquid into the flow path (500); the liquid to be ejected comes from a duct (134, 254) internal to the component (130, 250) and in fluid communication with a pipe (120, 220) that is external to the component (130, 250). Also disclosed is a method for cleaning a turbomachine by ejecting a washing liquid from one or more one stator aerodynamic components.
(FR)
L'invention concerne un composant aérodynamique de stator (130, 250) qui est destiné à être placé à l'intérieur d'un trajet d'écoulement (500) d'un fluide de travail d'une turbomachine (1000) ; le composant (130, 250) a une ou plusieurs buses (135, 255) servant à éjecter un liquide dans le trajet d'écoulement (500) ; le liquide destiné à être éjecté provient d'un conduit (134, 254) interne au composant (130, 250) et en communication fluidique avec un tuyau (120, 220) qui est externe au composant (130, 250). L'invention concerne également un procédé de nettoyage d'une turbomachine par éjection d'un liquide de lavage en provenance d'un ou de plusieurs composants aérodynamiques de stator.
