As an application of Stirling Engine heated by waste heat recovering or biomass combustion flame with its working fluid composed by incondensable (He, N2, H2, etc.), gas and condensable fluid (H_2O, etc.), the relation between heat recovery ratio and partial pressure of the condensable fluid are investigated. In addition, combination effects with multi-stage heater along with heat source flow, working fluid circulating flow system by lead valves, are studied. Through a simple modeling of 2-stage, circulating flow Stirling Engine with 10% partial pressure of H_2O vapor, the heat recovery ratio on the heater part increases approx. 2.4 times, compare with single stage normal Stirling Engine.
