ORC technology – transforming waste heat into green powerThe ORC (Organic Rankine Cycle) is a cyclic thermodynamic process. It uses an organic working fluid that enables the generation of electric power at comparatively low temperatures.
The cyclic process: simple principle, amazing effect
ORC technology involves passing heat through a heat exchanger, transferring its energy to the working fluid in a closed cycle that creates high pressure vapour, even at low temperatures. This pressure is used to drive a turbine connected to a generator. The vapour is returned to its fluid state in a condenser, cooled and then fed back into the vaporisation cycle.
