MODIFIKASI AIR INLET FILTER COMPARTMENT GTG PLTGU PT. INDONESIA POWER TAMBAKLOROK SEMARANG MENGGUNAKAN COMPUTATIONAL FLUID DYNAMICS

Abstract

PT Indonesia Power UBP Semarang operates 6 Gas Turbine Generator (GTG)Combined Cycle units in PLTGU Tambaklorok, which each of them have power ± 100 MW. The working of GTG, influenced by some things one of them is Pressure Loss. Pressure Loss is one of the causes of the performance power down in Gas Turbine and Air Inlet Filter Compartment at GTG. The construction of Air Inlet Filter Compartment at GTG PLTGU Tambaklorok Semarang consist to Sudden Contraction and three elbow so that there is Pressure Loss which cause much Power Loss. Then Reduce the Pressure loss by modification at Air Inlet Filter Compartment GTG PLTGU Tambaklorok Semarang increase perform GTG power output. Minimize the Pressure Loss and increase power output GTG by doing Air Inlet Filter Compartment GTG PLTGU Tambaklorok Semarang modification by adding Airfoil as director. The modification of Air Inlet Filter Compartment GTG PLTGU Tambaklorok Semarang modeling by using Computational Fluid Dynamic. Modification at Air Inlet Filter Compartment GTG PLTGU Tambaklorok Semarang by adding Airfoil as air director for increase ± 7 W GTG power output. Key Word : Power Output, Air Inlet Filter Compartment GTG, Pressure Loss Airfoil, Computational Fluid Dynamic.
