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 is the power output of the organic Rankine Cycle?
The low speed ORC process has an electricity output of 400–1100 kW and electricity to heat ratio of 0.18–0.22. The ORC-concept has two circuits, one for thermal oil and another for organic fluid.
What is the coefficient of performance of organic Rankine Cycle?
Compared to fossil fuel burners, it produces significant environmental and economic benefits given the high Coefficient of Performance (COP), between 3 and 4.
