What is the difference between Rankine cycle and organic Rankine cycle?
An organic Rankine cycle (ORC), is fundamentally the same as a steam Rankine cycle; however, it uses a lower boiling point organic fluid to better match its operation to lower temperature heat sources. ORC systems can achieve better efficiencies than steam turbines for smaller systems (less than a few MWe).
What is the difference between Rankine cycle and ideal Rankine cycle?
A real Rankine cycle or non-ideal cycle used in actual power plants do not undergo isentropic compression and expansion by pump and turbine respectively. These processes are irreversible compared to the ideal cycle, and there is an increase in entropy as shown in the T-s diagram below.
What is the difference between SRC and ORC?
... The ORC is similar to the conventional SRC but it uses an organic fluid (such as Freon) instead of water (steam) as a working fluid.
How many types of Rankine cycles are there?
The four main components of the Rankine cycle are the water pump, boiler, turbine, and condenser. There are four main stages to the Rankine cycle. Compression, heating, expansion, and condensation of the working fluid. The Rankine cycle can be represented by a pressure-volume diagram for each stage.
