Paper Abstract

Front surface temperature measurements made on the receiver at the 10 MWe Solar Thermal Central Receiver Pilot Plant near Barstow, CA are described. The receiver consists of 24 panels, each 45 feet long by 35 inches wide. Each panel is comprised of seventy half-inch diameter Incoloy tubes painted with an absorptive coating. Solar radiation, focused onto these panels, produces steam from water flowing through the tubes. The panel surface temperatures are needed to verify thermal-hydraulic computer codes used for performance predictions. Indications of large temperature gradients and fluctuations on a panel are needed in determining thermal stresses. The measurements were made using a commercial infrared camera/detector coupled with a 30X telescope to provide adequate resolution over large distances. The telescope and detector were located 660 feet from the receiver. Temperatures of one receiver panel were recorded during quasi-steady receiver operation. The trends of the results are corroborated with data obtained from receiver panel back surface thermocouples. The transient behavior of a panel section was recorded during a receiver shutdown, during which the focused radiation was quickly removed from the receiver. Results of the quasi-steady panel scan and the transient observation are presented.
