Moisture separator and reheater

A moisture separator and reheater comprising:

• a cylindrical casing extending in a horizontal axial direction, with opposite ends in the axial direction being sealed;
• and
• a heat exchanger tube group that heats steam entering into said casing, wherein
• a steam receiving port for receiving steam from outside is formed in a lower part of said casing, and a steam discharge port for discharging steam to outside is formed in an upper part of said casing,
• inside said casing there are formed:
• a steam receiving chamber into which steam flowing in from said steam receiving port enters;
• a supply manifold chamber communicating with said steam receiving chamber and adjacent to said steam receiving chamber in the axial direction;
• a moisture separating chamber communicating with said supply manifold chamber and adjacent to a lower part of said supply manifold chamber for separating moisture from steam;
• a heating chamber communicating with said moisture separating chamber, adjacent to said steam receiving chamber in the axial direction, and housing said heat exchanger tube group;
• and
• a collection manifold chamber communicating with said heating chamber and said steam discharge port and adjacent to said heating chamber and an upper part of said steam receiving chamber, wherein
• said steam receiving chamber, said heating chamber and said collection manifold chamber are separated by a transverse partition panel, a shroud and a ceiling panel,
• said transverse partition panel extends in a vertical direction, said heat exchanger tube group penetrates said transverse partition panel in the axial direction, and said transverse partition panel is disposed between said steam receiving chamber and said heating chamber,
• said shroud covers said end of said heat exchanger tube group penetrating said transverse partition panel,
• said ceiling panel is bonded to said transverse partition panel, and is disposed between said steam receiving chamber and said collection manifold chamber,
• in said steam receiving chamber, a reinforcing panel is bonded to said shroud or is integrally formed with a part of said shroud,
• said reinforcing panel includes a stress diffusion part for dispersing a force applied by a pressure difference between said steam receiving chamber and said collection manifold chamber,
• said stress diffusion part is bonded to a corner where said ceiling panel and said transverse partition panel come into contact with each other,
• said shroud has a side shroud,
• said reinforcing panel is bonded to said side shroud or integrally formed with said side shroud,
• an edge of said reinforcing panel is located on a side of said reinforcing panel opposite to said transverse partition panel, said edge having a circular arc shape depressed toward said transverse partition panel, and
• an arc center of the circular arc shape of said reinforcing panel is positioned closer to said transverse partition panel than a remote position farthest from said transverse partition panel in said shroud to which said reinforcing panel is bonded.
