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 are the working fluids in the ORC cycle?
This study considered five different working fluids for ORC, such as R245fa, Benzene, Methanol, Ethanol, and Acetone. The ORC generates additional electricity of 9.91 MW e for R245fa, 14.11 MW e for Benzene, 13.71 MW e for Methanol, 14.04 MW e for Ethanol and 13.97 MW e for Acetone.
What is the fluid in the Rankine cycle?
The organic Rankine cycle (ORC) uses an organic fluid such as n-pentane or toluene in place of water and steam. This allows use of lower-temperature heat sources, such as solar ponds, which typically operate at around 70 –90 °C.
The organic working fluid has a lower boiling point and higher vapor pressure than water and is therefore able to use low-medium temperature heat sources to ...

Jan 13, 2010 · A Kalina cycle is a thermodynamic cycle that is similar to the Rankine cycle, but it uses a mixture of ammonia and water as the working fluid.
It is a variation of the Rankine cycle named for its use of an organic, high-molecular-mass fluid (compared to water) whose vaporization temperature is lower ...
