Design and Development of Double Exposure Solar Cooker With Finned Cooking Vessel
Abstract
The main objective of this study is to design, construct and investigate the performance of a modified box type solar cooker supported by parabolic reflector disposed under the cooker. Energy cost for cooking purpose, indoor pollution and the time spent in gathering fuel woods are the main problems that led us to study and develop the cooker. Moreover, the very slow heat up time of box type cookers and their limitation for widespread deployment due to their low operating temperature are motivating factors to design this cooker. The developed cooker under field test gives stagnation plate temperature of 152°C. The “First figure of merit” of the cooker is 0.127 which represents the cooker marked as grade-A solar cooker. A comparative experimental study of double exposure solar cooker with two different cooking vessels (finned and un- finned) was also conducted and results show that under the same climatic conditions; temperature of finned cooking vessel and power are higher.
