Stationary booster reflectors for solar thermal process heat generation

摘要: The performance of a flat-plate collector with glass-foil double cover (LBM 4 GF) is compared to that the same one-sided external CPC booster reflector (RefleC-collector) for process heat generation up 150 °C. Efficiency curve measurements both variants are reported. Reference made simulation results annual energy gain in Wurzburg, Germany and Seville, Spain, at inlet temperatures 40 °C 120 In these simulations, novel model accounting anisotropy diffuse irradiance was used. Compared state-of-the-art simulations new calculates significantly higher additional gains reflectors. Both types were installed pilot plant Laundry Marburg, Germany. Monitoring one reference year overall system as well by reflectors given. It shown stationary highly increase efficient operation temperature range also covered flat-plates. Finally, simplified economic assessment carried out. Based on boosters, marginal costs an investment into assessed. estimated RefleC boosters should be below ca. 30 EUR/m² Wurzburg 55 Seville technology enter solar market.
