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.
How many types of Rankine Cycles are there?
Name | Summary |
Process 1–2 | Isentropic compression |
Process 2–3 | Constant pressure heat addition in boiler |
Process 3–4 | Isentropic expansion |
Process 4–1 | Constant pressure heat rejection in condenser |
What is the difference between Rankine cycle and modified Rankine cycle?
It simply a modification on the standard Rankine cycle. It reduces the volume of the condenser(i.e., material saving) by sacrificing small amount of work in the turbine. In modified Rankine cycle, steam is expanded to a pressure slightly less than the condenser pressure.
