| Abstract: | The present disclosure is directed to a cascaded recompression closed
Brayton cycle (CRCBC) system and method of operation thereof, where the
CRCBC system includes a compressor for compressing the system fluid, a
separator for generating fluid feed streams for each of the system's
turbines, and separate segments of a heater that heat the fluid feed
streams to different feed temperatures for the system's turbines. Fluid
exiting each turbine is used to preheat the fluid to the turbine. In an
embodiment, the amount of heat extracted is determined by operational
costs. |
