Results & Inferences

The experimental observations of the behavior of Fresnel lens concentrator alone as pre-heating device can improve the performance of desalination system. The experiment reveals a maximum temperature of 64 ?C in the heater tank at an average irradiance of 750 W/m2. The yield was increased by reducing the water level in the desalination tank and the increased yield was 2.8 liters with 15 liters of water in the desalination
