Abstract:
A method of operating a power generation system having a turbine for receiving a stream of first working fluid and expanding the first working fluid to produce power, a regenerative heat exchanger for receiving a stream of the expanded first working fluid from the turbine and a stream of second working fluid and for transferring heat from the expanded first working fluid to the second working fluid to heat the second working fluid and condense the expanded first working fluid, and a vapor generator for receiving a stream of the condensed first working fluid and transferring heat from an external heat source to the condensed first working fluid to heat the condensed first working fluid for use in the stream of first working fluid, comprising the steps of:operating the system in a first state of substantial equilibrium with the stream of second working fluid being received at a first flow rate; andoperating the system in a second state of substantial equilibrium with the stream of second working fluid being regulated so as to be received at a second flow rate, different than the first flow rate.
