Claims

[Scope of utility model registration request]

In a steam turbine reheating device for flowing steam from a steam source or high-pressure turbine bleed air into a heat transfer tube through a reheat steam header to heat turbine cycle steam flowing outside the heat transfer tube, the tube sheet of the reheat steam header is A reheating device for a steam turbine, characterized in that a communication hole is provided with a throat for controlling the amount of steam flowing into the heat transfer tube to the maximum flow rate.
