Abstract

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.
