Design, Construction and Testing of Parabolic Solar Oven

摘要

The work is on the Design, Construction and Testing of Parabolic Solar Oven with focused reflector. Heat from the sun was concentrated on a transparent glass located at the focal point; to the black casted Aluminum plate (absorber) which was located in an enclosed insulated space (Oven). The heat was absorbed by the Aluminum plate which could be utilized for baking or cooking. The sun tracking was made to be manual tilt of the parabolic reflector and a booster was mounted on top of the Oven which would focus the sun rays into the enclosed oven through the top glass layer. The frame was made using 50 mm×3 mm angle iron. The holder and its support were constructed out of 3 mm×12 mm flat bar and shaped round to accommodate the receiver holder. The principles of heat transfer were carried out to ascertain the efficiency of the oven. The system was tested in average sunny/cloudy conditions; the test results gave a higher temperature of 104°C.
