Abstract

Un anneau daube de stator pour le dernier étage dune turbine à vapeur à plusieurs étages comprend une pluralité de modules daube de stator définissant une chambre annulaire, chaque module daube de stator comprenant une partie daube allongée. La partie de lame allongée comprend en outre un passage longitudinal et une partie interne brasée à une première extrémité longitudinale de la partie de lame, la partie interne comprenant un trou traversant formant une partie de la chambre annulaire et un passage interne sétendant du trou traversant vers le passage longitudinal. Une partie externe est brasée sur une seconde extrémité longitudinale de la partie daube et en prise avec la turbine à vapeur. La partie externe comprend un passage externe ouvert sur une surface de la turbine à vapeur et le passage longitudinal.
