Organic Rankine Cycle

ORC scheme

Organic Rankine Cycle (ORC) is a key technology used for generating electricity from decentralized heat sources. Thanks to its
efficiency and flexibility, the ORC technology can be used to profitably recycle unused thermal energy at temperatures between 90 and 600 °C.

ORC technology by Dürr Cyplan

The ORC process is a steam cycle that uses heat to generate electricity. First, hot exhaust gas flows from the heat source (e.g. combustion engine) into the ORC module. There, the working medium is evaporated by the thermal energy. The pressurized steam is led into a turbogenerator, where part of its thermal energy is converted into electricity. Thereafter, the vapor is condensed by cooling. A pump injects the liquid working medium back into the evaporator.
