Abstract

Abstract: An air-cooled organic Rankine cycle (ORC) is applied to condense turbine exhaust of the steam Rankine cycle, thus a combined thermal system is established to achieve the cascade utilization of the energy. As a result, the condenser of the steam cycle is simultaneously used as the evaporator for the ORC system, which is called the dual phase heat exchanger (DPHE), and then the working fluid, R245ca, from the ORC turbine is condensed by the ambient air. Obviously, the performance of the DPHE is critical for the characteristics of the ORC cycle and the combined thermal system. The performance of the combined cycle is calculated at different temperature difference of the TPHE, and the relevant principles are also demonstrated.
