Abstract
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.
Claims11
A moisture separator comprising:
- a shell having a hollow shape;
- a steam inlet for introducing steam containing moisture into the shell;
- a moisture separating element that is provided in the shell, and separates the moisture contained in the steam that is supplied from the steam inlet and passes the moisture separating element;
- a steam outlet for discharging the steam after the moisture is extracted in the moisture separating element, the steam outlet being provided on an upper part of the shell;
- a drain outlet for discharging the moisture separated from the steam in the moisture separating element, the drain outlet being provided on a lower part of the shell;
- a first dividing wall for dividing a steam drift space from a drain path, the steam drift space causing the steam introduced from the steam inlet to pass the moisture separating element and to flow to the steam outlet, and the drain path leading the moisture separated in the moisture separating element to the drain outlet;
- a drain flow path for communicating between the steam drift space and the drain path to flow the moisture separated in the moisture separating element to the drain path;
- and
- a blow-up restraining unit for restraining the moisture of the drain path from reversing back through the drain flow path and from blowing up to a side of the steam drift space.
