Analisis Exergy Mesin Gas Pusat Listrik Pltmg Balai Pungut 7 X 15 Mw

Abstract

PLTMG have an efficiency increase of between 30-50%. This value is still not optimal because the utilization is less efficient. The engine is more often operated, the engine need maintenance for better performance. The decrease in
engine performance produces wasted energy so that engine efficiency is not optimal. In addition, the maintenance process takes a long time until the engine can be operated again. This is a problem because the maintenance process is
carried out on all cylinder engines. The purpose of this research are for calculating, analysing and testing of exergy destroyed in the cylinder unit of the Balai Pungut PLTMG gas fuel unit 4. From the analysis, the biggest efficiency of
energy is before overhaul which is 46,3 %.
