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.

ORC: How it works Where heat pumps use electrical power to create thermal energy for various purposes, an ORC system uses heat energy to generate electricity. In a typical ORC design, a thermal energy source feeds an evaporator to drive an expander or “reverse compressor”, which in turn generates the electricity.

Waste Heat Recovery System The total heat that could potentially be recovered can be calculated using this formula: Q = V×ρ×Cp×△T×η Flow rate (V) of gas inlet to gas conditioning tower in m 3 /hr Density of gas(ρ) corresponding to the gas temperature in kg\m 3 Specific heat (Cp ) of gas corresponding to the temperature ...

The Organic Rankine Cycle's principle is based on a turbogenerator working as a conventional steam turbine to transform thermal energy into mechanical energy and finally into electric energy through an electrical generator.
