Abstract

Design and construction considerations are given for a 1.8 x 3.7 m cylindrical parabolic focusing collector having a concentration ratio = 28. Built of commonly available materials, this tracking collector is intended to feed, by the exchange medium of oil, an Abbot-type solar oven. At 80°C the collection efficiency is .33, declining to .05 at 260°C (500°F). The dependence of black coatings on receiver pipe efficiency is studied. The reflectivity of vacuum deposited aluminum, buffed aluminum plate and shiny aluminum foil are compared. The greatest improvement in performance has come about by placing the collector on a shade free roof. Abbot's mirror was shaded past 1 o'clock.
