Abstract: “A solar receiver system has been designed installed and tested under real conditions in the faculty of Engineering, Tula’s Institute, Dehradun. The system consists of a heliostats with a solar central receiver. The function of this arrangement is to heat the basin water in order to increase temperature and pressure thus increase the solar still productivity. The influence of coupling the heliostats with the solar central receiver is reported, especially concerning distilled water productivity. A simple transient mathematical model is presented. The model is based on analytical solution of the energy-balance equations for different parts of the model. Numerical calculations ave een arrie ut r li ati e ra un n iti ns latitu e, E longitude). It is observed that the use of the proposed solar desalination system is to improve the accumulative productivity of arrangement by up to 90% when using 28 heliostats in three circle.”
