Title (EN) STEAM TURBINE SYSTEM AND COMBINED CYCLE PLANT
(FR) SYSTÈME DE TURBINE À VAPEUR ET CENTRALE À CYCLE COMBINÉ
(JA) 蒸気タービンシステム及びコンバインドサイクルプラント
Abstract:
(EN) A steam turbine system (200) includes a steam turbine (60) in which a main flow path (C) through which main steam flows is formed, and a saturated steam generation unit (210) that generates saturated steam. The saturated steam generation unit (210) feeds the saturated steam to a wet region (C1), in which the main steam in the main flow path (C) is in a wet state, through a hollow section formed inside a stationary blade (650) of the steam turbine (60). The stationary blade (650) has a plurality of supply ports formed so as to communicate the hollow section with the main flow path (C) and so that the discharge amount of the saturated steam increases from the inner circumferential side to the outer circumferential side in the blade height direction.
(FR) L'invention concerne un système de turbine à vapeur (200) comprenant une turbine à vapeur (60) dans laquelle un trajet d'écoulement principal (C) à travers lequel s'écoule de la vapeur principale est formé, et une unité de production de vapeur saturée (210) qui produit de la vapeur saturée. L'unité de production de vapeur saturée (210) alimente la vapeur saturée dans une région humide (C1), dans laquelle la vapeur principale dans le trajet d'écoulement principal (C) est dans un état humide, à travers une section creuse formée à l'intérieur d'une pale stationnaire (650) de la turbine à vapeur (60). La pale stationnaire (650) a une pluralité d'orifices d'alimentation formés de façon à faire communiquer la section creuse avec le trajet d'écoulement principal (C) et de telle sorte que la quantité de décharge de la vapeur saturée augmente du côté circonférentiel interne au côté circonférentiel externe dans la direction de hauteur de pale.
(JA) 蒸気タービンシステム(200)は、内部を主蒸気が流通する主流路(C)が形成された蒸気タービン(60)と、飽和蒸気を生成する飽和蒸気生成部(210)と、を備える。飽和蒸気生成部(210)は、蒸気タービン(60)の静翼(650)の内部に形成された中空部を介して、主流路(C)における前記主蒸気が湿り状態となっている湿り領域(C1)に、前記飽和蒸気を送り込む。静翼(650)は、前記中空部と主流路(C)とを連通させ、翼高さ方向の内周側から外周側に向かうにしたがって前記飽和蒸気の放出量が多くなるように形成された複数の供給口を有する。
