Selection of the optimum prime mover and the working fluid in a regenerative organic rankine cycle
A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...
متن کاملEffect of Working-fluid Mixtures on Organic Rankine Cycle System Performance: Heat Transfer and Cost Analysis
A thermodynamic limitation of single-component working fluids in organic Rankine cycles (ORCs) is the large exergy destruction (and, consequently, useful power loss) associated with evaporation and condensation. Due to their non-isothermal phasechange behaviour, non-azeotropic working-fluid mixtures have shown reduced exergy losses, leading to improved cycle efficiencies and power outputs. Thes...
متن کاملComparative investigation of working fluids for an organic Rankine cycle with geothermal water
In this paper, the thermodynamic investigation on the use of geothermal water (130 ◦C as maximum) for power generation through a basic Rankine has been presented together with obtained main results. Six typical organic working fluids (i.e., R245fa, R141b, R290, R600, R152a, and 134a) were studied with modifying the input pressure and temperature to the turbine. The results show that there are n...
متن کاملThermodynamic Performance of Regenerative Organic Rankine Cycles
ORC (Organic Rankine Cycle) has potential of reducing consumption of fossil fuels and has many favorable characteristics to exploit low-temperature heat sources. In this work thermodynamic performance of ORC with regeneration is comparatively assessed for various working fluids. Special attention is paid to the effects of system parameters such as the turbine inlet pressure on the characteristi...
متن کاملPerformance Benefits for Organic Rankine Cycles with Flooded Expansion
An organic Rankine cycle (ORC) is often used in waste heat recovery applications. These are typically small-scale applications where cycle thermal efficiency is low, and the benefits of traditional cycle enhancements (such as reheat stages or feed-water heaters) do not typically outweigh the costs required to implement them. An ORC with flooded expansion and internal heat regeneration is an alt...
