#2 Heat Recovery Boiler and #3 Steam turbine generator ( start-up date: January 2005).
#1 Gas Turbine
The gas turbine is a PG9171E gas turbine produced by GE, turbine number: 890040.
The gas turbine consists of a starter motor with a rated power of 1000KW, a 17-stage axial compressor, a combustion system consisting of 14 combustion chambers, and a 3-stage turbine rotor.
Axial compressor rotor and turbine rotor are connected by flange and have 3 supporting bearings.
The generator of the gas turbine is a synchronous generator with air cooling, three-phase, two-pole, alternating current of 3000rpm, frequency of 50HZ and solid cast iron rotor.
The output power of the generator is 120MW (running at base load).
The exciter is an AC exciter with rotating diode rectification, and the excitation method is brushless excitation.
