What is the supercritical Rankine cycle?
Technical options for Organic Rankine Cycle systems
A supercritical or transcritical cycle is a cycle with a maximum pressure higher than the critical one. Working fluid is heated up from subcooled liquid to superheated vapor with a smooth transition above the critical point.
What is the organic Rankine cycle?
Organic Rankine Cycles (ORC) are systems that can effectively recover low-grade heat for electric power generation. For ORC to be a viable technology, it should operate safely and efficiently under variable operating conditions due to exogenous and operating specifications changes.
What is the supercritical ORC cycle?
The supercritical ORC aims to enlarge the expansion in the turbine to generate more power such that the evaporation process occurs above the critical pressure of the working fluid. In a regenerative ORC, a heat exchanger is placed between the fluid exiting the turbine and that exiting the pump.
