Operating principle Cyplan® ORC
First, heat flows from a heat source into the ORC module, via a heat transfer fluid (gas, steam, thermal oil, water). There, the working fluid is transformed into pressurized vapor using the thermal energy of the heat source. The pressurized vapor is led into a turbo generator, where part of its thermal energy is converted into electricity. The vapor is expanded in the turbine, generating mechanical energy, which drives a generator coupled to the turbine. Thereafter, the vapor is condensed by a heat extractor. A pump injects the liquid working fluid back into the evaporator, where it is vaporized again. The heat to power transfer loop is closed. The extracted heat may be used as useful heat (up to 95°C) for follow up processes.
The demand for controllable, flexible technologies for generating power, such as CHP units, is rising in response to the need to stabilize electrical grids and to compensate for fluctuations caused by renewable energy production. Our Cyplan® ORC technology is a proven, economical way of boosting efficiency in combination with stationary gas engines (CHP units), and its innovative Flex-Plus technology ensures flexible routine operation thanks to an intelligent plant control system and components that can be subject to varying loads. This means the Cyplan® ORC solutions are perfectly equipped to deal with the future increases in requirements in the electricity market as profitable power-generating heat exchangers for gas engines.
