- A new and novel means of combining solar energy with the Rankine engine is to use the collectors as the engine boiler. This report details the results of a test program where a small (288 square feet) collector field was installed and used for boiling-in-the-collector tests with R-113 as a working fluid. Two different types of parabolic trough tracking collectors were purchased and tested. There were two rows (128 sq. ft.) of Del Manufacturing collectors and one row (160 sq. ft.) of Solar Kinetics collectors. All three rows were installed at a 5 degree angle (inclined to the South) oriented North-South and tracking East-West on the roof at Barber-Nichols in Arvada, Colorado, a northwest suburb of Denver. These two types of collectors have distinct differences that made it worthwhile to test each type. A Rankine engine, less turbine expander, was installed and used to complete a solar power system. The major experimental results are that the collectors did heat the R-113, did provide a vapor suitable for turbine feed, and stable flow did occur under all conditions, thus proving the feasibility of the boiling-in-collector concept. Also, the 5 degree angle performed satisfactorily and is considered a reasonable angle for field use. Some unexpected problems were experienced in testing the collectors. The feasibility of the system concept has been demonstrated and areas for improvement have been determined. Methods to resolve these areas are proposed along with a plan to expand the system, complete the engine, and to gather operating experience and performance data for a year's operation. Budget and schedule are provided for this proposed follow on work. (WHK)
