What are the steps in the organic Rankine cycle?
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 organic Rankine cycle?
An Organic Rankine Cycle (ORC) system is a closed thermodynamic cycle used for power production from low to medium-high temperature heat sources ranging from 80 to 400°C and for small-medium applications at any temperature level.

What is Rankine cycle steps?
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.
Organic Rankine cycles may play an important role in reducing these emissions since they can be operated by using industrial waste heat of renewable energies.
