Analisis Kinerja Backpressure Steam Turbine-Generator Di PT. XYZ

Abstrak

Steam turbines are widely used in various industrial sectors, especially in the Liquefied Natural Gas (LNG) industry. The purpose of this research was to analyze the performance of three backpressure steam turbine units by calculating and comparing the isentropic efficiency under actual parameter conditions with the design parameter conditions. The effect of isentropic efficiency indicates the actual performance of the steam turbine, which is important for optimizing steam utilization. The highest isentropic efficiency was found in the PG-10 turbine unit at 58.27%, while the lowest was in the PG-09 turbine unit at 18.10%. The PG-13 turbine experienced the highest decrease in isentropic efficiency of 11.91%, followed by the PG-09 turbine at 8.98% and the PG-10 turbine at 4.94%. An unusual pattern was also observed in the steam flow rate and electrical power output profiles of the PG-13 turbine unit. Kata kunci: Backpressure Turbine, Isentropic Efficiency, Steam Turbine.
