ABSTRACT:
A two-stage harmonic reciprocating Stirling engine has a primary heater and a pair of regenerators with an intermediate heat exchanger disposed in the fluid flow between the two regenerators. High temperature heat above 5000.degree. F. is supplied to the heater head of the engine while lower temperature, otherwise wasted, heat between 500.degree. F. and 1500.degree. is supplied to the intermediate heat exchanger. The lower temperature heat can be from exhaust gases of the primary burner, or can be waste heat from another process for use in a cogeneration installation.
