Abstract
A method comprises heating a feedwater stream in a feedwater heater, boiling the feedwater stream in a boiler to produce a steam stream, superheating the steam stream in the boiler to produce a superheated steam stream, producing power using the superheated steam stream to produce an outlet steam stream, using a first portion of the outlet steam stream to provide heat for the heating step, and modulating the flow of the first portion of the outlet steam stream below a full flow to allow the superheated steam stream to meet a superheated steam set point.
