Abstract

An energy recovery arrangement is disclosed for use with an engine. The energy recovery arrangement may include a closed circuit containing a high-pressure working fluid, a first boiler configured to receive waste heat from a first source on the engine, and a second boiler disposed upstream of the first boiler and configured to receive waste heat from a second source on the engine. The energy recovery arrangement may also include an energy extractor disposed at a location downstream of the first and second boilers, a condenser disposed at a location downstream of the energy extractor, and a pump disposed at a location downstream of the condenser and upstream of the first and second boilers. The energy recovery arrangement may further include a recuperator disposed in parallel with the second boiler and configured to transfer heat from working fluid exiting the extractor to working fluid exiting the pump.
