Organic Rankine Cycle (ORC)

OCR Process Diagram

What is “ORC”?

The Organic Rankine Cycle is a thermodynamic process where heat is transferred to a fluid at a constant pressure. The fluid is vaporized and then expanded in a vapor turbine that drives a generator, producing electricity. The spent vapor is condensed to liquid and recycled back through the cycle.

The Organic Rankine Cycle makes use of an organic fluid with a boiling point lower than water. The fluid enables recovery of heat from lower temperature sources such as BIO-Mass. The low temperature heat is used to drive a turbine and create electricity.
