A method was proposed to couple the heat source with ORCs (Organic Rankine Cycles). The integrated-average temperature difference, ΔTave, quantifies the thermal match in the evaporator. ΔTave decreases with increase in critical temperatures (Tc). The fluid with Tc approaching Tgas,in (flue gas...

The thermal performance of supercritical pressure ORCs (Organic Rankine Cycles) is related to the critical temperature of the organic fluids. The heat source in this investigation was flue gas with an inlet temperature of 150 °C and an outlet temperature of 70 °C. The working fluids were...
