Desalination through diesel engine Exhaust Waste heat

Abstract

The aim of this work is to utilize the heat energy wasted in exhaust gas of an IC engine of low capacity for distillation desalination using a submerged horizontal tube straight pass evaporator and a condensing unit, without aid of any external energy use for pumping system. In this work a Horizontal tube Straight pass evaporator designed fabricated and experiments were conducted. The performance of the SHTE analyzed under various load condition. The work proven that 1.8 liter/hr of saline water can be desalinated from the 5 HP Engine Exhaust gas, without affecting the performance of the engine. By utilizing the heat energy in addition to increase in overall efficiency the thermal Pollution is also reduced considerably.
