 Performances of Rankine-cycle engines as functions of their expanders' efficienciesO. Badr, P.W. O'Callaghan and S.D. Probert Applied Energy, 1984, vol. 18, issue 1, 15-27 Abstract: There is a growing interest in the recovery and utilisation of low-grade heat (e.g. from waste exhaust gases of thermal power and industrial plants, [`]solar' collectors, as well as from geothermal sources) in order to produce mechanical work. Rankine-cycle engines, using organic working fluids, have proven prospects for these applications. In this investigation, the dependence of the performance of a low-grade energy Rankine-cycle engine, using refrigerant 113 as the working fluid, upon the efficiency of the engine's prime mover (i.e. the expander) is evaluated. For low-grade energy applications, the expander's efficiency is the most influential parameter dictating the overall efficiencies of both the simple and the regenerative Rankine-cycle engines. Therefore, for each proposed application, attention should be devoted towards the selection of the most appropriate expander type and then improving its performance characteristics in order to maximise the overall efficiency of the Rankine-cycle engine.
