Thermodynamic Efficiency Maximum of Simple Organic Rankine Cycles

Thermodynamic 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...

Thermodynamic Comparison of Organic Rankine Cycles Employing Liquid-Flooded Expansion or a Solution Circuit

Performance 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...

Thermodynamic Analysis and Optimization of a Novel Cogeneration System: Combination of a gas Turbine with Supercritical CO2 and Organic Rankine Cycles (TECHNICAL NOTE)

Thermodynamic analysis of a novel combined system which is combination of methane fired gas turbine cogeneration system (CGAM) with a supercritical CO2 recompression Brayton cycle (SCO2) and an Organic Rankine Cycle (ORC) is reported. Also, a comprehensive parametric study is performed to investigate the effects on the performance of the proposed system of some important parameters. Finally, a ...

تحلیل انرژی-اگزرژی و مطالعۀ پارامتری بازیابی گرمای اتلافی پیکربندی‏های مختلف سیکل توربین گاز با استفاده از سیکل رانکین آلی

Since ordinary gas turbine cycles in actual condition comprise simple cycle, regenerative cycle, reheat cycle and intercooler cycle between high pressure and low pressure compressors, these cycles include 16 combined cycles by combining with a Rankine cycle that consists of three organic fluids and steam. In the present work, the thermodynamic analysis of the above combined cycles with three or...
