摘要： Systems and methods for recovering energy from waste heat are provided. The system includes a waste heat exchanger coupled to a source of waste heat to heat a first flow of a working fluid. The system also includes a first expansion device that receives the first flow from the waste heat exchanger and expands it to rotate a shaft. The system further includes a first recuperator coupled to the first expansion device and to receive the first flow therefrom and to transfer heat from the first flow to a second flow of the working fluid. The system also includes a second expansion device that receives the second flow from the first recuperator, and a second recuperator fluidly coupled to the second expansion device to receive the second flow therefrom and transfer heat from the second flow to a combined flow of the first and second flows.

摘要： Waste heat energy conversion cycles, systems and devices use multiple waste heat exchangers arranged in series in a waste heat stream, and multiple thermodynamic cycles run in parallel with the waste heat exchangers in order to maximize thermal energy extraction from the waste heat stream by a working fluid. The parallel cycles operate in different temperature ranges with a lower temperature work output used to drive a working fluid pump. A working fluid mass management system is integrated into or connected to the cycles.

摘要： Various thermodynamic power-generating cycles are disclosed. A turbopump arranged in the cycles is started and ramped-up using a starter pump arranged in parallel with the main pump of the turbopump. Once the turbopump is able to self-sustain, a series of valves may be manipulated to deactivate the starter pump and direct additional working fluid to a power turbine for generating electrical power.

摘要： Cascade thermodynamic energy conversion cycles use multiple power turbines in a working fluid circuit for conversion of waste heat energy, with each turbine inlet temperature optimized to operate in a temperature spectrum to use a greater amount of thermal energy from each cycle. Various accompanying recuperator arrangements are also disclosed, and working fluid mass management systems integrated with the cascade cycles.
