Title (EN) TRANSITION PIECE
(FR) RACCORD DE RÉDUCTION
(JA) トランジションピース
Abstract:
(EN) This embodiment of a transition piece introduces combustion gas that is generated inside a liner inner tube of a combustor liner, which has a double pipe structure comprising the liner inner tube and a liner outer tube, into a turbine. The transition piece comprises: an inner tube that is connected to the outlet side end of the liner inner tube and that introduces the combustion gas discharged from the liner inner tube to the turbine; an outer tube that is connected to the outlet side end of the liner outer tube and that is provided so as to cover the outer circumference of the inner tube with a gap therebetween; and a rib that projects from the outer circumferential face of the inner tube toward the outer tube side wherein the surface of the outer face thereof abuts the inner circumferential face of the outer tube, and that has a through-hole that circulates a cooling medium discharged from the combustor liner side and flowing in the gap.
(FR) Selon un mode de réalisation, l'invention concerne un raccord de réduction destiné à introduire un gaz de combustion, produit à l'intérieur d'un tube interne d'une chemise de chambre de combustion comportant une structure à double tuyau comprenant le tube interne de chemise et un tube externe de chemise, dans une turbine. Le raccord de réduction comprend : un tube interne relié à l'extrémité côté sortie du tube interne de chemise et servant à introduire le gaz de combustion, évacué du tube interne de chemise, dans la turbine; un tube externe relié à l'extrémité côté sortie du tube externe de chemise et agencé de façon à recouvrir la circonférence externe du tube interne avec un écartement entre les deux; et une nervure faisant saillie à partir de la face circonférentielle externe du tube interne vers le côté tube externe, la surface de sa face externe venant en butée contre la face circonférentielle interne du tube externe, et comportant un trou traversant permettant de faire circuler un agent de refroidissement évacué du côté chemise de chambre de combustion et coulant dans l'écartement.
(JA) 実施の形態のトランジションピースは、ライナ内筒およびライナ外筒で構成される二重管構造を有する燃焼器ライナの前記ライナ内筒内で生成した燃焼ガスをタービンに導く。前記トランジションピースは、前記ライナ内筒の出口側端部に接続され、前記ライナ内筒から排出された前記燃焼ガスを前記タービンに導く内筒と、前記ライナ外筒の出口側端部に接続され、間隙空間を介して前記内筒の外周を覆うように設けられる外筒と、前記内筒の外周面から前記外筒側に突出すると共に、その外面側の表面が前記外筒の内周面に当接し、前記燃焼器ライナ側から排出されて前記間隙空間を流れる冷却媒体を流通させる貫通孔を有するリブとを備える。
