Comparative analysis of the use of flash evaporator and solar still with a solar desalination system

Abstract

The present research paper shows the use of a flash evaporator coupled with the solar desalination system to improve the distillate output. Here solar desalination system consists of a solar water heater coupled with evacuated tubes, a flash evaporator and a condenser. Also, two sets of experiments have been utilised for the use of a flash chamber with a solar desalination system and a solar still with a solar desalination system. Experimental set-up has been fabricated at Government Polytechnic Ahmedabad, Gujarat and tested for seven days 1st May to 7th May 2019. From the experimental days, it has been found that the distillate output of the solar desalination system with a flash evaporator obtained an average of 13.95 kg as compared with the solar still of 4.29 kg. From the experiments, it has been concluded that the flash evaporator is a possible solution to improve the distillate output of the solar desalination system.
