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 working principle of organic Rankine cycle?
The ORC-concept has two circuits, one for thermal oil and another for organic fluid. Heat from burning fuel or industrial waste is led in via the oil-filled circuit at a temperature of 250–300 °C to the heat exchanger, creating steam and super heating the organic silicon fluid.
What is Rankine cycle and its working principle?
The Rankine cycle or Rankine Vapor Cycle is the process widely used by power plants such as coal-fired power plants or nuclear reactors. In this mechanism, a fuel is used to produce heat within a boiler, converting water into steam which then expands through a turbine producing useful work.
What is Q in Rankine cycle?
η=WnetQin=1−QoutQin. The basic Rankine cycle is presented in terms of temperature and entropy change in Figure 10.2. The ideal state of this cycle is reflected in the vertical lines 1-2 and 3-4, when the fluid compressed and expanded. Those processes are shown to proceed isentropically, i.e., without entropy change.
