ABSTRACT:
A method of operating a power generation system is provided. The system includes a turbine, a regenerative heat exchanger, and a vapor generator. The turbine receives a stream of working fluid and expands the working fluid to produce power. The regenerative heat exchanger has a plurality of condensing heat exchangers which transfer heat from the expanded working fluid to condense the expanded working fluid. The vapor generator vaporizes the condensed portions of working fluid to form the stream of working fluid. In operating the system, a respective portion of the expanded working fluid is directed to each of the condensing heat exchangers, and the amount of condensed working fluid at at least one of the condensing heat exchangers is regulated.
