Second generation sodium heat pipe receiver for a USAB V-160 Stirling engine: Evaluation of on-sun test results using the proposed IEA guidelines and analysis of heat pipe damage
- German Aerospace Research Establishment, Stuttgart (Germany). Inst. for Technical Thermodynamics
Dish/Stirling technology has demonstrated the highest conversion efficiencies of all solar thermal conversion systems. At the DLR a second generation sodium heat pipe receiver for the Schlaich Bergermann und Partner (SBP) 9-kW{sub e} dish/Stirling system has been developed and constructed. Long-term operation occurred from Oct. 1992 until Aug. 1993 at the Plataforma Solar de Almeria (PSA) in Spain, accumulating 950 operating hours. The performance of the SBP 9-kW{sub e} system with a sodium heat pipe receiver is evaluated according to the guidelines for dish/Stirling performance evaluation by Stine and Powel, as proposed to the International Energy Agency (IEA). Tests were stopped due to a leak in the receiver absorber surface. The analysis of this damage is reported.
