Abstract
A method of operating a power plant is provided. The method includes channeling saturated steam at a first pressure to a pressure control device, superheating the steam by decreasing the pressure of the saturated steam from the first pressure to a second pressure using the pressure control device, and channeling the superheated steam towards a steam turbine component to facilitate cooling the component.
Claims20
A method of operating a power plant, said method comprising:
- channeling saturated steam at a first pressure to a pressure control device;
- superheating the steam by decreasing the pressure of the saturated steam from the first pressure to a second pressure using the pressure control device;
- and
- channeling the superheated steam towards a steam turbine component to facilitate cooling the component.

A cooling system for use with a steam turbine, said cooling system comprising:
- a saturated steam source;
- and
- a pressure control device coupled in flow communication with said saturated steam source, said pressure control device facilitates reducing the pressure of saturated steam to form superheated steam, said pressure control device configured to couple in flow communication with the steam turbine for supplying superheated steam thereto.
A combined-cycle system comprising:
- a gas turbine;
- a steam turbine coupled to said gas turbine via a rotor shaft;
- and
- a steam turbine cooling system coupled in flow communication with said steam turbine, said cooling system comprising:
- a saturated steam source;
- and
- a pressure control device coupled in flow communication with said saturated steam source, said pressure control device configured to superheat saturated steam.
