ABSTRACT:
A heat exchanger-combustion chamber construction includes a combustion chamber and a heat exchanger chamber. Disposed in the heat exchanger chamber is an array of inlet tubes, the outlets of which discharge into the combustion chamber. Combustion products discharged from the combustion chamber are flowed over the inlet tubes in heat exchange relation. An array of aspirator sleeves of larger inner dimension than the outer dimension of the inlet tubes is secured to divider structure between the heat exchanger chamber and the combustion chamber, each aspirator sleeve receiving the outlet end of a heat exchanger tube while permitting longitudinal movement of the heat exchanger tube within the sleeve (due to thermal expansion, for example). Inlet vapor flow through the tubes produces a reduced pressure effect in the sleeves to a value below the pressure of the exhaust gas in the heat exchanger chamber so that there is recycle flow of a small fraction of the combustion products through the aspirator sleeves back into the combustion chamber.
