ELECTRICITY GENERATION FROM WASTE HEATORGANIC RANKINE CYCLE (ORC) TECHNOLOGY
2
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 ther mal energy at temperatures between 90 and 600 °C.
MAKE THE MOST OUT OF YOUR WASTE HEAT YOUR WASTE HEAT
ORC technology by Dürr Cyplan:
» CO2free electricity generation from waste heat
» Increase in energy efficiency » Conservation of resources » More independence through the use of
selfgenerated energy

ORC TECHNOLOGY BY DÜRR CYPLAN 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, and a pump injects the liquid working medium back into the evaporator.
COMBINED RECUPERATOR/CONDENSERYour benefits:» Compact system design» Minimal pressure losses» Ideal heat transfer
CONTROL PANEL/CONTROLLERYour benefits:» Fully automated operation» Remote monitoring» Compact module ready to connect
DIRECT EVAPORATORYour benefits:» Simple incorporation without intermediate circuit» Greater safety» Better energy utilization» Easy maintenance
HERMETICALLY SEALED TURBOGENERATORYour benefits:» No additional lubricating circuit» Swivel-mounted turbine support for simple maintenance» Greater efficiency through freely selectable operating speed» Ideal blades for high pressure conditions
Your benefits:» Combined heat and power production with feed line temperatures up to 90 °C
