Abstract
A new design of a stepped solar desalination system with flashing chamber is experimentally investigated. The main objective of the investigation was to study the performance of step—wise water basin coupled with a spray water system by augmenting desalination productivity through using two air heaters. The effect of using the spray system for seawater is investigated experimentally at different velocities of the water sprays holder and Flow rates on the performance of the solar still in a previous article by the authors [ll. in the present article the effect of the inlet raw water temperature (at motor speed of 250 rpm and watt flow rate of`•¢l l/h) and the power consumed by the two air beaters (at both 100 and 250 rpm and water flow rates3.635 4.0 and 9.333 l/h) on the performance of the proposed solar system are investigated. It was found that the productivity and performance of the system were significantly positive dependent on both inlet impure water temperature and the power consumed. They decrease with the increase of inlet impure water temperature. At 250 rpm the productivity and efficiency increases with the power consumed to a certain limits after which they begin to decreases gradually while at l00 rpm the productivity and so the efficiency decreases with the power consumed gradually
