摘要：

The optical design of a fixed mirror line-focus solar concentrator, using curved mirror elements whose radius of curvature is matched to the radius of the reference cylinder of the concentrator, is presented. It is shown that this design leads to a considerable decrease in the transverse width of the focal intensity profile as compared with a fixed mirror solar concentrator of similar design made of flat mirror elements, and thus enables reduction in the cost of the heat receiver assembly. The development of a stretched tape construction of a 12 m x 3 m fixed mirror solar concentrator, conforming to the above design by using cold rolled steel tapes with constant levels of curvature across their width as substrates for the curved mirror elements, is briefly reported. Results from optical tests on the concentrator, which confirm the predictions from the theoretical model of the optics of the concentrator, are presented.
