Title (EN) COMBUSTOR AND GAS TURBINE
(FR) CHAMBRE DE COMBUSTION ET TURBINE À GAZ
(JA) 燃焼器、及びガスタービン
Abstract:
(EN) Provided is a combustor comprising: a nozzle body (16) having a shaft body (24) extending along an axis, the shaft body (24) having a purge air flow passage (29) formed therein so as to extend along the axis to the front end of the shaft body (24), the purge air flow passage (29) allowing compressed air to be introduced therein, the shaft body (24) also having an air injection hole (39) formed at the front end of the shaft body (24) and connecting the purge air flow passage (29) and the outer surface of the shaft body (24), the nozzle body (16) also having a swirling blade (26) protruding from the outer peripheral surface of the shaft body (24) in the radial direction of the axis and swirling, about the axis, fluid flowing to the downstream side in the direction of the axis, the nozzle body (16) further having a fuel injection hole (38); and a sealing member (40) for sealing the air injection hole (39) and formed from metal having a lower melting point than metal which forms the nozzle body (16).
(FR) L'invention concerne une chambre de combustion, laquelle chambre comprend : un corps de buse (16) ayant un corps de tige (24) s'étendant le long d'un axe, le corps de tige (24) ayant un passage d'écoulement d'air de purge (29) formé dans ce dernier de façon à s'étendre le long de l'axe jusqu'à l'extrémité avant du corps d'arbre (24), le passage d'écoulement d'air de purge (29) permettant à de l'air comprimé d'être introduit dans celui-ci, le corps d'arbre (24) ayant également un trou d'injection d'air (39) formé à l'extrémité avant du corps d'arbre (24) et reliant le passage d'écoulement d'air de purge (29) et la surface externe du corps d'arbre (24), le corps de buse (16) ayant également une pale de tourbillonnement (26) faisant saillie à partir de la surface périphérique externe du corps d'arbre (24) dans la direction radiale de l'axe et faisant tourbillonner, autour de l'axe, un fluide s'écoulant vers le côté aval dans la direction de l'axe, le corps de buse (16) ayant en outre un trou d'injection de carburant (38) ; et un élément d'étanchéité (40) pour sceller hermétiquement le trou d'injection d'air (39) et formé à partir d'un métal ayant un point de fusion inférieur à celui du métal qui forme le corps de buse (16).
(JA) 燃焼器は、軸線に沿って延びる軸体(24)であって、軸体(24)の内部において軸体(24)の先端部まで軸線に沿って延びて圧縮空気が導入されているパージ空気流路(29)と、軸体(24)の先端部に形成されてパージ空気流路(29)と軸体(24)の外面とを接続する空気噴射孔(39)と、を有する軸体(24)、軸体(24)の外周面から軸線の径方向に張り出して、軸線方向の下流側に流れる流体を軸線回りに旋回させる旋回羽根(26)、及び燃料噴射孔(38)を有するノズル本体(16)と、空気噴射孔(39)を封止し、ノズル本体(16)を形成する金属よりも融点の低い金属によって形成されている封止部材(40)と、を備える。
