The main goal of present article is to see how adding graphite powder and black paint to the absorber plate can increase solar still yield. Therefore, two identical in size solar stills called modified solar still (MSS) and Conventional solar still (CSS) have been fabricated and tested in Patan district, Gujarat, during October 2019. MSS used graphite powder mixed with black paint, and CSS used as reference still in current research work. The current research was done with tap water as the raw water. Graphite powder concentrations have varied from 20% to 40% found 10.5 to 17% enhancement in yield. Mixing carbon powder with black paint shows improvement in a rise in water temperature and heat transfer rate than CSS. According to the results, the yield of MSS was higher than the yield of CSS during experimental days. It is concluded that the payback time of MSS with 20% weight concentration and CSS found 117 days and 121 days.

太阳能蒸馏器吸收板上的石墨粉与黑色涂料混合以提高产量:一项实验研究

本文的主要目的是了解在吸收板中添加石墨粉和黑色涂料如何提高太阳能蒸馏器的产量。因此,2019 年 10 月在古吉拉特邦帕坦地区制造并测试了两个大小相同的太阳能蒸馏器,称为改良型太阳能蒸馏器 (MSS) 和传统太阳能蒸馏器 (CSS)。MSS 使用石墨粉与黑色油漆混合,CSS 用作在目前的研究工作中仍可参考。目前的研究是用自来水作为原水进行的。石墨粉浓度从 20% 到 40% 不等,发现产量提高了 10.5% 到 17%。碳粉与黑色涂料的混合比CSS在水温上升和传热率方面有改善。结果表明,实验期间MSS的产量高于CSS的产量。
