This paper describes the advantages of operating a non-imaging collector in a mode where steam is generated directly in the collector, rather than using a heat transfer oil and a secondary heat exchanger. The predicted performance advantages from generating steam directly in the collectors are significant, and that performance was verified using a collector built and tested at Argonne National Laboratory. A description of the collec-tor and the test method used to test the collector while operating in a steam generating mode is also presented by this paper. Test results are included for a 6.4 m2 array of evacuated tube collectors with an advanced absorber coating, silver reflectors, and tubes oriented in a N-S configuration.
