Data collected during the measurement campaign in Fall 1982 were used to determine the thermal efficiency of the Sulzer receiver as a function of power into the cavity, time of day, and beam irradiance. At an insolation of 900 W/m, receiver efficiency of about 87% and thermal efficiency of about 60% were measured. The thermal efficiency over time of operation (8’50”) on a clear day (October 7, 1982) comes to 57%. Converting this value to the total day from sunrise to sunset (11’25”) by 8’50” of operation, one gets an average efficiency of 50%.
