口と動翼入口との間の外周部に蒸気中の水滴を除
去できる旋回室を設けた蒸気タービンにおいて、
動翼外輪との間に蒸気の通路となる間隙をもたせ
かつ動翼シユラウド前縁との間の間隙をほとんど
無くすように取付けた環状のドレン仕切板により
、水滴を分離・除去後の蒸気を反転させて動翼先
端外周部にもどすようにした蒸気タービン段落。 In a steam turbine that operates in a humid steam region and is equipped with a swirling chamber that can remove water droplets in the steam at the outer periphery between the stationary blade outlet and the rotor blade inlet,
The annular drain partition plate is installed so that there is a gap between the rotor blade outer ring and the leading edge of the rotor blade shroud, and there is almost no gap between it and the leading edge of the rotor blade shroud, and the steam is reversed after water droplets are separated and removed. A steam turbine stage in which the rotor blades are moved back to the outer periphery of the rotor blade tips.
