Experimental Investigation of the Effect of Basin angle on the Performance of stepped solar still coupled with parabolic concentrator
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
Water is one of the prime elements responsible for life on the earth. It covers three-fourth of the surface of earth. However most of the earth’s water is found in oceans which contain too much salt and cannot be used for drinking. Also the remaining minor part of fresh water, excluding glaciers, ice caps available on earth suitable for human requirements is getting polluted. In the present work it is suggested to purify the water using solar energy, which is available abundantly at free of cost. The device that purifies through evaporation with solar heat an energy source is known as solar still. Solar still is a simple device that purifies the water which is eco-friendly and economical. The performance of solar still depends on the rate of evaporation. Any attempt that improves the evaporation rate results in improvement of the performance of solar still. In the present attempt it is proposed to analyze the performance of single stepped solar still associated with parabolic concentrator which increases the feed water temperature and in turn evaporation rate. From this experiment it is obtained that the stepped solar still yields the maximum productivity when it is placed at the inclination (α) 120. Orientation of both stepped solar still basin and parabolic concentrator is also suggested to position in North-South direction to obtain maximum productivity.
