چکیده

Aiming at improving the performance of Organic Rankine Cycle (ORC) system with low-grade steam as heat source, this work studied and optimized main operating parameters ORC system. The effects evaporation temperature, superheat degree, condensation temperature regenerator pinch difference on were obtained. optimization for is based indicators specific net power output, waste pollution, cycle exergy efficiency, total UA value (the product overall transfer coefficient area exchanger). results show that increase decrease can improve general but lead to weaker economic performance. optimal are determined 139°C, 4°C, 36°C 8°C, respectively, reaching output 114.73 kW, efficiency 37.10%. Besides, it indicated regenerative reach 13.6% additional compared without regenerator.

Optimal Heat Source Temperature For Supercritical Organic Rankine Cycle

Organic Rankine Cycle (ORC) enables power generation from lowto medium temperature heat sources. In an ORC, the organic medium shows different performances for different heat source temperatures. For a range of heat source temperatures, one temperature can be always identified corresponding to the best thermal match between the heat transfer fluid and working fluid. This temperature is defined ...

Parametric Optimization of Regenerative Organic Rankine Cycle System for Diesel Engine Based on Particle Swarm Optimization

To efficiently recover the waste heat from a diesel engine exhaust, a regenerative organic Rankine cycle (RORC) system was employed, and butane, R124, R416A, and R134a were used as the working fluids. The resulting diesel engine-RORC combined system was defined and the relevant evaluation indexes were proposed. First, the variation tendency of the exhaust energy rate under various diesel engine...
