High Pressure Transfer Pump Efficiency Calculation Before And After Reverse Engineering at PLTGU XYZ

Steam Gas Power Plant (PLTGU) is a power plant that uses gas as fuel and reuses exhaust gas from the gas turbine to heat the pipes in the HRSG (Heat Recovery Steam Generator) to produce steam and rotate the steam turbine. PLTGU XYZ is a Gas and Steam Power Plant which has 2,154 MW. One of the important components used in PLTGU is the high-pressure transfer pump. A high-pressure transfer pump is a pump that functions to move water from the low-pressure drum through the high pressure economizer to the high pressure drum, using an automatic system. The type of high-pressure transfer pump at PLTGU XYZ is Type MC100-300/9. To maintain the efficiency of the high-pressure transfer pump, components need to be maintained or replaced. high pressure transfer pump components have been replaced on the pump shaft using the reverse engineering method. Before reverse engineering the large pump shaft the efficiency was 66%, and after reverse engineering the large pump shaft the efficiency was 63%, so the comparison of pump efficiency before and after reverse engineering the pump shaft was 3%.
