The customer generates electricity and heat in a biogas-fired combined heat and power plant (CHP). The heat generated is fed into a district heating network, which also covers the heat demand of the biogas plant in addition to a school center and industrial plants. To increase the electrical power output, an ORC system is to be installed, which converts the thermal energy of the CHP flue gas partly into electrical energy. The challenge here was the integration of the ORC system while maintaining the existing heat concept.
For this project, we have installed a Cyplan® ORC 70 HT CHP as a suitable ORC module, which provides about 275 kWth. The flexible heat extraction up to 95° C leads to our untouched heat condenser. Another advantage is that this compact module is very space-saving. This project and the predominant innovation was supported by the Environmental Technology Award of the State of Baden-Württemberg.
The advantage of a Cyplan® ORC system, as in this case, is the great innovation due to the direct evaporation of the flue gas. The transmission losses of the ORC system are minimized by the simple integration, so that the system achieves the highest efficiency and the best efficiency. Due to the low number of wear parts, the customer will incur minimal maintenance costs, thus ensuring an overall economic package. This provides a basis for highest profitability. Furthermore, our systems have a heat extraction up to 90° C and a power-generating exhaust gas heat exchanger.
Without exception, in this performance class we are unrivaled in the Organic Rankine Cycle market.
