Description Overview The module has two gas turbines GE 9FA.03 (DLN2+) and one steam turbine GE D11. Each GT exhaust is directed to the triple pressure unfired, natural circulation horizontal, type CMI USA HRSG. This configuration helps turndown operation of station up to 45%. Specifications The station is based on robust design of GE gas turbine with high efficiency DLN2+ dry low NOx system. Each GT is site rated for an output of 235 MW. The triple pressure reheat GE D11 steam turbine with downstream exhaust is site rated at 266 MW. The HRSG is a triple pressure, natural circulation, horizontal design type with deaerator atop the LP drum. Net combined cycle efficiency at site condition is approximately 57% on LHV basis. The inherent design of the gas turbine reduced the NOx emissions < 25 ppmvd. Noise level of the station is below 85 dB. The machines operating frequency is 50 Hz and the power factor 0.85. Location And Ambient Conditions Site elevation above MSL: 27 meters. Ambient temperature: 29 deg C. Relative humidity: 70%. Major Operation Parameters Base load gas requirement per GT is 1.5 million standard cubic meter per day (MMSCMD). Base load gross heat rate on GCV basis: 1780 kcal/kWh. Nominal station auxiliary power consumption is < 3%. Major Equipment And Run Hours Run hours: nil (designed maintenance cycle hot gas path inspection (HGPI) 24000 hrs and major inspection (MI) 48000 hrs).
