Abstract

Generator Air Cooler is a main component in system of PLTA with the water is used as working fluid for cooling the hot air. Cooling water containt of sediment or soluted particle risk to influence heat transfer. The main purpose of this research is to determine the influence of soluted particle (SiO2) in water on the effectiveness of generator air cooler in system of PLTA. The research on the effectiveness of generator air cooler (GAC) with 5 varies of concentration SiO2 in water and 5 varies of volume rate for each concentration is held in Laboratorium of Power Plant System II of Machine Department of State Polytechnic of Ujung Pandang. The temperature of air to GAC is kept constant with the value of 950C. Then recording the temperature of water in and out GAC, the temperature of air in and out GAC. As a result, it was founded that the maximum value of effectiveness was 6% at concentration SiO2 of 4% and at the lowest volume flow rate of 0,54 l/min, then the value of effectiveness decreases along the increasing value of volume flow rate and concentration SiO2.
