What is the organic Rankine cycle ORC process?
The ORC turbogenerator uses medium-to-high-temperature thermal oil to preheat and vaporize a suitable organic working fluid in the evaporator (4>5). The organic fluid vapor rotates the turbine (5>6), which is directly coupled to the electric generator, resulting in clean, reliable electric power.
How do you calculate Rankine cycle?
Formulas related to Rankine cycle –
1
Heat Addition(qa)=h1−h4.
2
Heat Rejection (qr)=h2−h3.
3
Work done by Turbine (wt)=h1−h2.
4
Work taken by Pump (wp)=h4−h3.
5
Thermal Efficiency ηthermal=wt−wpqa.

NetWork Output (wn)=wt−wp.
7
Back Work Ratio(BWR)=wpwt.
8
Specific Steam Consumption. h1 = Enthalpy at Turbine Inlet.
What is the maximum efficiency of ORC?
Efficiency. 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 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).
