Experimental Investigation on A Modified Solar Still with Thermal Storage System

Authors(2) :-Sonu Prakash Yadav, Rajiv Varshney

The efficiency of conventional solar still is quite low and applications are only limited to sun shine hours. In this research a modified solar still with steps, external reflector and thermal storage system has been designed. The conventional and modified solar stills were designed and fabricated and their performance was compared. After performing experiments it was found that the maximum temperature of water in the steps of modified solar still (MSS) and in the basin of conventional solar still (CSS) was recorded as 65oC and 59oC, respectively. The CSS basin water temperature was found to be higher than MSS step water temperature up to 11:00 am. Afterwards, the trend shows the higher temperature range of MSS step water as compared to CSS basin water temperature till the end of experiment i.e. 06:00 pm. The hourly production of distillate for MSS is higher than that of CSS during the entire time period of experimentation. The maximum hourly distillate collected from MSS and CSS was 325 ml and 135 ml at 2:00 pm. The maximum increase in the hourly productivity of MSS was found to be 692% higher than that of CSS i.e. about 8 times.
