Exhaust gas waste heat recovery heat exchanger for use in heat recovery system, has working fluid flow path extending through housing between working fluid inlet and working fluid outlet

摘要

The exchanger has a working fluid flow path (246) extending through a housing (236) between a working fluid inlet and a working fluid outlet, where the path includes a portion adjacent to the working fluid inlet and another portion spaced apart from the working fluid inlet. The flow of the working fluid along the latter portion of the working fluid flow path is parallel to the flow of the exhaust along an exhaust flow path adjacent to the latter portion of the working fluid's flow path. Independent claims are also included for the following: (1) a heat recovery system comprising a turbine (2) a method for recovering waste heat from exhaust (3) an integrated heat exchanger comprising a recuperator.
