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...

A dynamic organic Rankine cycle using a zeotropic mixture as the working fluid with composition tuning to match changing ambient conditions

Air-cooled condensers are widely used for Organic Rankine Cycle (ORC) power plants where cooling water is unavailable or too costly, but they are then vulnerable to changing ambient air temperatures especially in continental climates, where the air temperature difference between winter and summer can be over 40 C. A conventional ORC system using a single component working fluid has to be design...

Effect 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...

Comparative 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...

Analysis and Simulation of the Effect of Turbine Inlet Temperature on Thermodynamic Performance of the Water – Ammonia Combined Cycle

Due to the importance of power generation cycles including combined cycle, many studies have been done in recent years and many researchers have been tried to optimize these cycles by using of existing methods. In this study, the Water-Ammonia cycle is investigated in the combined-cycle of the Water-Ammonia, working dual Water-Ammonia mixture is used as the works fluid. This cycle can be used f...
