What is the efficiency of an organic Rankine Cycle?
The efficiency of current high temperature Organic Rankine Cycles does not exceed 24%. Typical steam Rankine cycles show a thermal efficiency higher than 30%, but with a more complex cycle design (in terms of number of components or size).
What are the steps in the organic Rankine Cycle?
The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, screw, scroll, or other expander), and then through a condenser heat exchanger where it is finally re-condensed.
How to find cycle efficiency?
To calculate cycle efficiency, divide Value-Added Production Time by the Total Cyle Time. For reference, Total Cycle Time is the summation of all activities associated with the work on a unit from start to finish.
