Karakteristik Unjuk Kerja Kompresor Dan Turbin Pada Sistem Micro Gas Turbine Berbahan Bakar Liquified Petroleum Gas (LPG)

Abstract

There are so many remote areas in Indonesia that do not have electricity supply. As time goes by, oil prices are getting more expensive and also getting thinner. This is inversely proportional to the state of the industry in Indonesia which is developing and is followed by an increase in Indonesia’s population. A gas turbine is an energy conversion engine, which converts kinetic energy into mechanical energy. One of the gas turbine engine is a turbocharger. The performance of the turbocharger is to supply air with a density that exceeds the density of atmospheric air into the cylinder to be compressed in the compression stroke. Micro gas turbines are gas turbines designed with small power of about 25 kW to 500 kW. This study uses an experimental method to obtain empirical data. This research variation uses the equivalence ratio with a value of more than 1. The object of this research is compressor work and turbine work. The results of the study, it is known that the equivalence ratio has an effect on compressor work and the turbine work. The result of the equivalence ratio of more than 1, the highest compressor and turbine work values are 0.0044 𝑘𝐽/𝑠 and 1.93 𝑘𝐽/𝑠
