STEAM TURBINE WITH ROTATABLE STATOR BLADES

The steam turbine (200) has a plurality of expansion stages (261, 262, 271) and stator blades (221, 222, 231) upstream at least one of the expansion stages (261, 262, 271); in order to regulate steam flow inside the steam turbine (200) and maximize turbine efficiency, the angular positions of the st...

Beschreibung
Zusammenfassung:	The steam turbine (200) has a plurality of expansion stages (261, 262, 271) and stator blades (221, 222, 231) upstream at least one of the expansion stages (261, 262, 271); in order to regulate steam flow inside the steam turbine (200) and maximize turbine efficiency, the angular positions of the stator blades (221, 222, 231) are controlled for example by an external control unit through e.g. a command rod (289, 299) during operation of the steam turbine (200). 蒸汽涡轮(200)具有多个膨胀级(261、262、271)以及在膨胀级(261、262、271)中的至少一个膨胀级上游的定子叶片(221、222、231)；为了调节蒸汽涡轮(200)内部的蒸汽流并使涡轮效率最大化，在蒸汽涡轮(200)的操作期间，定子叶片(221、222、231)的角位置例如由外部控制单元通过例如命令杆(289、299)来控制。
