PENGARUH KONSENTRASI SILIKON OKSIDA (SiO2) DALAM AIR TERHADAP EFEKTIVITAS GENERATOR AIR COOLER PADA SISTEM PLTA

Abdul Rahman, Firman Firman

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.
