Abstract:
This paper presents the design, development and performance characteristics of a low cost solar steam generating system which incorporates recent design and materials innovations of parabolic dish technology. The concentrator is a deep dish of rather imperfect optics, made of silvered polymer
refiectors fitted in the aluminum frame of a satellite communication dish. Conventional cavity receivers
tend to be inadequate for this concentrator. Semi-cavity and modified cavity receivers, thermally optimised, with the fuzzy focal image have, therefore, been investigated. Preliminary field measurements
and cost, as well as performance analyses of the system, indicate a solar to steam conversion efficiency of 70-80% at 4508C and a collector system cost of Rs 8000-9000/m2 (US$1=Rs, 40.0).
