Organic Rankine Cycle

 

Rankine cycle is a process of converting heat into shaft power. Organic Rankine Cycle (ORC) is a process of converting heat into shaft power using organic material as the working fluid.

 

The process consists of

(1-2) Pumping of working fluid

 

(2-3) Extracting of heat by the working fluid

 

(3-4) Expansion of the working fluid to generate shaft power

 

(4-1) Cooling of the working fluid

 

The ORC consists of :

1. Pump

2. Boiler / Evaporator

3. Turbine / Expander (generator)

4. Condenser
