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.
What is the maximum efficiency of Rankine cycle?
Subcritical steam Rankine cycles are currently used in all operating solar thermal power plants. However, thermal efficiencies of these power cycles are limited to about 42%. New types of power cycles are required to generate power at higher efficiencies in order to drive down the cost of solar thermal electricity.
