ABSTRACT:
A recuperative heater for heating the heater heads of an external combustion machine includes a recuperative heat exchanger having an axial pass section partially surrounding the combustion chamber. Combustion products pass from the recuperative heat exchanger to a condensing exhaust gas heat surrounding the axial pass section and comprising a cylindrical exhaust gas passage ringed externally by a water jacket. Water from the water jacket may be circulated to a thermal load. A top cover of the heater opposes the heater heads or hot end of the engine. Inner and outer plenums are formed between the combustion chamber wall and the top cover and inlet air is heated in stages as its enters the outer plenum, passes into the axial pass section, into the inner plenum, then into the combustion chamber.
