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...

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...

in this paper, the amount of wasted heat from different parts of a 12 liter compression ignition engine and their potential for waste heat recovery were investigated. then, two-stage configuration of organic rankine cycle was introduced for simultaneous heat recovery from exhaust gases and coolant. finally, parameters like hybrid generated power, engine thermal efficiency and brake specific fue...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...
