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?
An Organic Rankine Cycle (ORC) system is a closed thermodynamic cycle used for power production from low to medium-high temperature heat sources ranging from 80 to 400°C and for small-medium applications at any temperature level.
What are the steps in the organic Rankine cycle?
Similar to a simple Rankine cycle, a basic organic Rankine cycle (ORC) consists of four processes: increasing pressure of the working fluid through a pump, high temperature heat addition through an evaporator, expansion of the high temperature as well as high pressure fluid through a turbine, and low temperature heat ...
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.
