Direct absorption receiver experiments and concept feasibility

Technical Report ·
OSTI ID:6927874

This report presents the results of recent experiments on the direct absorption receiver (DAR) concept using molten salt as the working fluid. These experiments were aimed at determining whether the DAR concept is technically feasible and were carried out at the Advanced Components Test Facility, Atlanta, Georgia. Results are based on several days of operating with solar flux ranging up to 50 W/cm/sup 2/ and also on a numerical model capable of predicting the thermal performance of the DAR salt film. Issues relating to thermal efficiency, absorber-to-salt heat transfer, and salt film stability are addressed.
