摘要
A method of operating a power generation system is provided. The system includes a turbine, a regenerative heat exchanger, a boiler, and a superheater. The turbine receives a stream of first working fluid and expands the first working fluid to produce power. The regenerative heat exchanger receives a stream of the expanded first working fluid from the turbine and a stream of second working fluid, for example from the RHE or DCSS of a Kalina type system. The exchanger transfers 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. The boiler receives and vaporizes a stream of the condensed first working fluid. The superheater receives and superheats the vaporized stream of first working fluid and the heated stream of second working fluid to form the stream of first working fluid. In operating the system, first heat is transferred from the expanded first working fluid to the second working fluid to superheat the second working fluid and condense the expanded first working fluid. Condensed first working fluid from another stream of the condensed first working fluid is combined with and thereby desuperheats the superheated second working fluid. Second heat from the expanded first working fluid is transferred to and thereby heats the desuperheated second working fluid without condensing the expanded first working fluid to form the heated stream of second working fluid.
