ANALISA SISTEM PENDINGIN PADA ALAT DESTILASI AIR LAUT BERBAHAN BAKAR GAS UNTUK MENDAPATKAN AIR BERSIH DAN GARAM

Abstract

Sea water becomes the greatest potential that we can take as clean water and salt. This research uses 3 kg LPG gas fuel, gas stove and cooler to get clean water productivity using distillation method. By varying the opening of 1/4, 2/4, 3/4, and 4/4 gas stove as a seawater heater in a pot, the performance of the device is as follows: at aperture ¼ obtained η heat efficiency of 42.99% with heat transfer rate q 161,68 watt with the highest achievement of clean water productivity 550 ml and gas usage equal to 416 gr, Aperture 2/4 obtained by heat efficiency η 37,29% with heat transfer rate q equal to 159,64 watt with highest achievement of clean water productivity 820 ml and gas usage of 746 gr. Aperture 3/4 obtained by heat efficiency η equal to 33,01% with heat transfer rate q equal to 160,26 watt with highest achievement of 900 ml clean water productivity and gas usage as much as 886 gr. Aperture 4/4 obtained η heat efficiency of 27.75% with a heat transfer rate q of 161,99 watts with the highest achievement of 1100 ml clean water productivity and 975 gr of gas usage. Keywords: Sea water, gas fuel, gas stove, coolant, efficiency, heat transfer rate, temperature.
