摘要： In a moisture separator, a manifold that communicates with a steam inlet is disposed in a shell. A plurality of blowout outlets for steam is provided on a side of the manifold. A first support plate and a lower support frame are fixed to a lower part in the shell to compart a steam drift space and a drain path. A moisture separating element is provided corresponding to the manifold, and steam from which moisture is removed by the moisture separating element is heated by a group of heating tubes to flow as high-temperature reheat steam to the steam outlet. The moisture is led from the drain opening through the drain path to the drain outlet. A blocking plate blocks a part of the drain opening.
