| description | PROBLEM TO BE SOLVED: To provide a steam turbine capable of switching between a stable operation emphasizing power generation output and a stable operation emphasizing power generation efficiency.SOLUTION: A steam turbine includes an inner ring groove 36 provided in an inner ring 35, a planting part 32 provided in a stationary blade 31 and fitted into the inner ring groove 36, an outer ring groove 34 provided in an outer ring 33, and the planting part 32 provided in the stationary blade 31 and fitted into the outer ring groove 34. The inner ring groove 36 and the outer ring groove 34 extend toward a turbine shaft direction into an arc shape when viewed from a turbine radial direction, and the elevation angle of the stationary blade 31 is changed when sliding the stationary blade 31 along the inner ring groove 36 and the outer ring groove 34.
【課題】発電出力重視の安定した運用と、発電効率重視の安定した運用とを切り替えることができる蒸気タービンを提供すること。【解決手段】内輪３５に設けられた内輪溝３６と、静翼３１に設けられ、内輪溝３６に嵌合される植込み部３２と、外輪３３に設けられた外輪溝３４と、静翼３１に設けられ、外輪溝３４に嵌合される植込み部３２とを備え、内輪溝３６および外輪溝３４は、それぞれ、タービン径方向から見たとき、タービン軸方向に円弧状に延びており、内輪溝３６および外輪溝３４に沿って静翼３１をスライドさせると、静翼３１の迎角が変更されるものとする。【選択図】図２ |
