Heat Loss Measurements on Parabolic Trough Receivers

Eichel, Paul and Dreyer, Sebastian and Gnaedig, Tim and Hacker, Zdenek and Janker, Sebastian and Kuckelkorn, Thomas and Silmy, Kamel and Pernpeintner, Johannes and Lüpfert, Eckhard (2010) Heat Loss Measurements on Parabolic Trough Receivers. SolarPACES 2010, 21.-24. Sept. 2010, Perpignan.



A measurement set-up to determine the heat losses of single parabolic trough receiver components at steady state conditions has been developed at Schott. This paper describes the functionality of the set-up and a comparative campaign with three Schott receivers of 7.0, 8.9 and 11.1% emittance (400°C) including test stands at German Aerospace Center (DLR) and U.S. National Renewable Energy Laboratory (NREL). This campaign showed generally good agreement with deviations <10%. Additionally, results are compared to heat loss predictions derived from optical measurements of the absorber coating via a one-dimensional simulation. The general trend suggests good accordance with a systematical deviation at lower emissivities. Overall, this non destructive measurement technique provides a good possibility to determine an important receiver specification, its heat loss.
