750 MW each, UNUSED Gas Based Complete Combined Cycle Power Plants
2 units available
Technical Specifications:
The Project Details:
1. EACH 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%.
2. 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 and 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. Thus Net Combined cycle efficiency at Site condition
is approx 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.
