Abstract

Taking good advantage of the diesel-exhaust with the Organic Rankine Cycle (ORC) System contributes to raising the thermal efficiency, saving fuel consumption and reducing the cost, since there is much energy carried by the diesel-exhaust. There come some problems on the match for the temperature of heat source when the ORC system uses pure fluids as working fluids, so we considered adopting zeotropic mixture working fluids to solve the problems and improving the comprehensive properties of thermodynamics. The zeotropic mixture performs better than the pure fluid at the thermal efficiency,exergy efficiency, net work and the expansion ratio in the regenerative cycle, while it has no superiority than the pure fluid in the basic process. The study of zeotropic mixture suggest that the higher the temperature of the heat source and the lower the temperature of the cold source is ,the higher cycle thermal efficiency and net work are. When taking cycle net work as target function, there is the optimal evaporation temperature and superheat degree. We should choose the suitable evaporation temperature first because its priority is higher than the superheat degree by comparing different influence factors on the cycle.
