Title (EN) DEAD LEG DEBRIS EXTRACTOR FOR CONTINUOUS ON-LINE OPERATION
(FR) EXTRACTEUR DE DÉBRIS DE TRONÇON MORT POUR FONCTIONNEMENT EN LIGNE CONTINU
Abstract:
(EN) A system and a method for removing debris from a flow path of a cooling flow is provided. The system includes a turbine including at least one airfoil. A cooling flow is communicated to cooling holes (40) via piping (60) that includes a dead leg debris extractor (70, 80) in order to cool the airfoil. The dead leg debris extractor (70, 80) includes a means to capture and retain debris from the cooling flow continuously during online operation of the turbine.
(FR) L'invention concerne un système et un procédé d'élimination de débris à partir d'un trajet d'écoulement d'un flux de refroidissement. Le système comprend une turbine comprenant au moins un profil aérodynamique. Un flux de refroidissement est communiqué à des trous de refroidissement (40) par l'intermédiaire d'une tuyauterie (60) qui comprend un extracteur de débris de tronçon mort (70, 80) afin de refroidir le profil aérodynamique. L'extracteur de débris de tronçon mort (70, 80) comprend un moyen pour capturer et retenir des débris à partir du flux de refroidissement de façon continue pendant le fonctionnement en ligne de la turbine.
