Organic Rankine Cycle (ORC)

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.

Project Details

Construction of two plants, one in Fraser Lake BC and one in Chetwynd BC. Each plant consisted of two 6MW Turboden ORC powered turbines. Thermal Oil energy was achieved on both sites using furnace burners with twin reciprocating grate combustion systems. A multicyclone and electrostatic precipitator remove particulate matter from the exhaust gas stream, while a recuperator recycles heat back into the combustion chamber and boosts the system’s overall efficiency.
