Abstract: 

In this analysis an inclined basin type solar was fabricated and tested for desalination of water with and without biomass boiler as heating source. An Inclined type Flat plate collector is designed in a conventional type solar still to act as collector. This collector was experimented in solar and biomass modes for comparison. The inclined flat plate collector tray was of dimension 1m2 and 3 mm thick G.I. Sheet was painted black and was attached with biomass boiler the inclination of the plate is 30. Different water depths of 2cm, 3cm, were maintained in the conventional basin of the still and evaporation rates are analyzed. To enhance productivity of the still, sensible heat storage materials such as stone, iron scarps, sand were packed inside the wick and stretched at both ends and placed on the inclined flat plate collector. In order to improve capillary effects sponges of various sizes were placed on the inclined basin. Maximum evaporation rate was found for 2cm water depth 1530 kg/m2 with The maximum evaporation rate for conventional still with 2cm depth was 680kg/cm2 For the various packing materials used highest evaporation rate is obtained for 2cm water depth with iron scarp packed inside the wick having 1400kg/cm2 Maximum productivity was achieved for still coupled with biomass heat source.
