Title (EN) GAS TURBINE
(FR) TURBINE À GAZ
(JA) ガスタービン
Abstract:
(EN) This gas turbine comprises: a cooling air tube (19) for feeding cooling air to a cooling air main passage (8a) of a rotor main body (6), the cooling air tube (19) being disposed downstream of the rotor main body (6) without being in contact with the rotor main body (6); a bearing downstream-end shaft seal (27) disposed downstream of a bearing (29) for rotatably supporting the rotor main body (6), and also disposed in an annular shape around the external periphery of the rotor main body (6); and a recovery flow channel member having a leaked air recovery flow channel (30) for leading cooling air (A1), which has leaked from the bearing downstream-end shaft seal (27) toward the bearing (29), into an exhaust flow channel (13) through which flows combustion gas (G) that has passed through a final rotor blade stage (9).
(FR) L'invention concerne une turbine à gaz comprenant : un tube d'air de refroidissement (19) permettant d'envoyer de l'air de refroidissement à un passage principal d'air de refroidissement (8a) d'un corps principal de rotor (6), le tube d'air de refroidissement (19) étant situé en aval du corps principal de rotor (6) sans être en contact avec celui-ci ; un joint d'arbre d'extrémité aval de palier (27) situé en aval d'un palier (29) permettant de supporter en rotation le corps principal de rotor (6) et étant également de forme annulaire autour de la périphérie extérieure du corps principal de rotor (6) ; et un élément canal de flux de récupération comportant un canal de flux de récupération de fuite d'air (30) permettant d'acheminer l'air de refroidissement (A1), qui a fuit du joint d'arbre d'extrémité aval de palier (27) vers le palier (29), dans un canal de flux d'échappement (13) par lequel circule le gaz de combustion (G) qui a traversé l'étage final de pales de rotor (9).
(JA) 本発明に係わるガスタービンは、ロータ本体(6)の下流側にロータ本体(6)とは非接触で配置され、ロータ本体(6)の冷却空気主通路(8a)に冷却空気を送る冷却空気配管(19)と、ロータ本体(6)を回転可能に支持する軸受け(29)よりも下流側であってロータ本体(6)の外周側に環状に配置されている軸受下流端軸シール(27)と、軸受下流端軸シール(27)から軸受け(29)側に漏れた冷却空気(A1)を、最終動翼段(9)を通過した燃焼ガス(G)が流れる排気流路(13)中に導く漏れ空気回収流路(30)が形成されている回収流路部材と、を備える。
