Use of fluid mixtures for increasing the electrical efficiency of ORC processes in selected fields of application

• Applicant: Professor Dr.-Ing. Dieter Brüggemann
• Subject Area: Technical Thermodynamics
• Term: from 2010 to 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 159298697

A main objective of the project continuation is to enrich the results already achieved for the use of zeotropic mixtures in ORC power generation from heat sources of 150 °C to 350 °C . Further prospective mixtures shall be studied as well as a supercritical operation. Experiments shall be performed to measure the heat transfer of selected mixtures in finned tubes. Data will be compared to theoretical correlations. Finally a low-power turbine will implemented to validate results and to evaluate the overall system.
