Increasing the Productivity of V-Type Solar Still Augmented with Biomass Heat Source
A. Senthil Rajan | S. Tharunkarthikeyan | A. Alaudeen
Abstract: A solar still with a 0.9 ? 0.8 ? 0.75-meter v-type stepped design was fabricated using galvanized iron sheet and tested with varying water depths from 2 to 4 centimeters, in combination with a biomass heat source. The one end of the basin becomes attached with a heat exchanger having zero.1/2 m diameter and 4.5 m duration, and having five numbers of bends. The feature of the warmth exchanger is to transfer high temperature electricity from biomass warmness supply to the saline water in the nevertheless at a consistent present day charge using circulate pump. Numerous strong, sensible, latent warmth garage materials and evaporative surface materials are used within the nevertheless alongside one of a kind colour dyes delivered inside the nevertheless to boom the saline water temperature. To convey down the glass cowl temperature, the outer glass become cooled using sprinkler manually at normal c program language period. Experiments have been conducted with biomass heat supply for non-stop circulates mode and sun warmth radiation mode. An inward slope of the glass cover was maintained towards the center of the nevertheless and the cover was cemented by using chemical adhesive to decrease air leakage An outlet is also supplied to empty out distilled water and a 2? slope is maintained for the water collection channel for easy outward float of distilled water. The performances of changed nonetheless have been compared with conventional nonetheless of the same size strolling underneath the equal meteorological situations. The tremendous, sensible heat garage materials produce 58% more productivity than traditional nonetheless. Also, evaporative substances produce 20% greater productiveness than traditional nonetheless. The performance of the v-still with continuous flow mode produces greater efficiency than solar mode. The performance of traditional still changed into depressed while as compared with all other sorts of operation. Black coloration dye performs well while compared with different colour dyes. Sprinkler, solar still 14% more than conventional still. The main objective of this work is to investigate the performance of the inclined flat plate solar still integrated with and without biomass boiler along with sensible heat storage materials and evaporation material. A biomass boiler supply heat in to the still through heat exchanger. Various water depths of 2cm, 3cm were analyzed. Various combinations of sensible, evaporative materials were used in the still to increase productivity. Glass cover cooling is provided with the help of wicks and manual cooling at regular interval of time to increase condensation rate. To increase evaporative area sponges, wicks were used along with sensible materials. Materials such as sand, metal pieces, stones, were used as the sensible heat materials. The performances of still with biomass boiler are compared with performances of still without biomass boiler.
