Claims

[Scope of utility model registration request]

A reheat header that is divided into a high temperature chamber and a low temperature chamber through a corner wall is provided on the outside of the tube wall, and a tube plate is installed so that one end of each of the many U-shaped heat exchanger tubes is communicated with the high temperature chamber. while the other end is connected to the tube sheet so as to communicate with the low temperature chamber, and the base heat vapor from the high temperature chamber is guided to the low temperature chamber through the U-shaped heat transfer tubes, and In a moisture separator reheater that performs reheating by guiding the steam to be heated to a U-shaped heat exchanger tube group by a guide plate surrounding the U-shaped heat exchanger tube group, A moisture separator reheater characterized in that the cross-sectional area of a passage for heated steam is changed in accordance with the heat transfer capacity of a large number of heat transfer tubes.
