Analisa Kerja Turbin dan Kompresor Pada Turbin Gas Mikro Berbahan Bakar Liquefied Petroleum Gas (Lpg)

Abstract

Micro-scale energy plants are alternative technologies that communities can use to meet their daily energy. Micro-scale energy plants can be applied to domestic, office, and rural communities. Micro-steam turbines, micro hydro turbines, and micro gas turbine. Micro gas turbine (micro turbine) are gas turbines designed to generate a small force in the 25-500 kW range. Micro gas turbine is also one of the developments of power plants from the Zero Energy Building (ZEB) concept. This study used experimental method with variations in Air Fuel Ratio (AFR) 2,25; 4,30; 5,33 by looking directly for cause-and-effect data through experiments, to get the empirical data. In this case research object observed is the compressor work, turbine work, compressor efficiency, and turbine efficiency of micro gas turbine. Air fuel ratio 5,33 has a compressor work, turbine work and the highest efficiency of the compressor at a rate of 0,0615 kJ/s, 1,737 kJ/s, and 72,75 %. The highest turbine efficiency, fueled by air fuel ratio 2,25 with a value of 47,39 %
