Title
(DE) BRENNKAMMER SOWIE VERFAHREN ZUR DAMPFKÜHLUNG EINER BRENNKAMMER
(EN) COMBUSTION CHAMBER AND METHOD FOR COOLING A COMBUSTION CHAMBER WITH VAPOUR
(FR) CHAMBRE DE COMBUSTION ET PROCEDE DE REFROIDISSEMENT PAR VAPEUR D'UNE CHAMBRE DE COMBUSTION
Abstract
(DE) Die Erfindung betrifft eine Wandstruktur (3), wobei die Wandstruktur (3) eine zwischen einer Innenwand (6) und einer Außenwand (7) angeordnete Zwischenwand (12) aufweist. Für Kühlfluid, insbesondere Kühldampf (11), münden ein Einlaß (9) in einen zwischen Außenwand (7) und Zwischenwand (12) befindlichen Außenkühlraum (13) und ein Auslaß (10) in einen zwischen Zwischenwand (12) und Innenwand (6) befindlichen Innenkühlraum (14). Die Zwischenwand (12) weist Öffnungen (15) zur Durchströmung mit dem Kühlfluid (11) auf. Die Erfindung betrifft weiterhin ein Verfahren zur Dampfkühlung einer Brennkammer (1) einer Gasturbine.
(EN) The invention relates to a wall structure (3) with an intermediate partition (12) between an inner wall (6) and an outer wall (7). An inlet (9) leading to an external cooling area (13) located in between the outer wall and the intermediate partition (12) and an outlet (10) leading to an inner cooling area (10) located in between the intermediate partition (12) and the inner wall (6) are provided for the cooling liquid, especially for cooling vapour (14). The intermediate partition (12) has openings (15) allowing cooling fluid (11) to flow through. The invention further relates to a method for cooling a gas turbine combustion chamber (1) with vapour.
(FR) L'invention concerne une structure (3) de paroi comportant une paroi intermédiaire (12) placée entre une paroi intérieure (6) et une paroi extérieure (7). Il est prévu pour le fluide de refroidissement, notamment de la vapeur de refroidissement (11), un orifice d'entrée (9) qui débouche dans un espace de refroidissement extérieur (13) situé entre la paroi extérieure (7) et la paroi intermédiaire (12), et un orifice de sortie (10) qui débouche dans un espace de refroidissement (14) situé entre la paroi intermédiaire (12) et la paroi intérieure (6). La paroi intermédiaire (12) comporte des ouvertures (15) pour permettre le passage du fluide de refroidissement (11). L'invention concerne en outre un procédé de refroidissement par vapeur de la chambre de combustion (1) d'une turbine à gaz.
