DETAILED PERFORMANCE ANALYSIS OF THE 10KW CNRS-PROMES DISH/STIRLING SYSTEM

Kurzfassung

The campaign to measure the optical and thermodynamic efficiency of the system will be presented. The optical quality was determined with a classical flux-mapping using a lambertian target and a CCD camera system, which also leads to the energy input to the PCU. For the thermodynamic analysis all the data necessary for a complete energy balance around the Stirling engine, i.e. efficiency of the Stirling motor, the cavity and the receiver as well as the parasitic losses were measured. Such a detailed performance analysis helps to quantify all significant losses of the system and to identify the most rewarding future improvements.
