2. Technical Description of Power Plant Equipment.
Three aero derivative Gas Turbines, LM6000 PC- Sprint type, constructed and
supplied by General Electric (GE). The nominal power of the plant is 147.762 MW.
Water (demineralized) Injection System is installed in order to reduce the NOx
emissions and also increase the efficiency of the engine when the ambient
temperature is high. The GTs are dual fuel (Gas and/or Diesel).
The LM6000 gas turbine is a dual-rotor, concentric drive-shaft gas turbine. The
main components consist of a variable inlet guide vane (VIGV) assembly, a 5-stage
low-pressure compressor (LPC), a 14-stage variable-geometry high-pressure
compressor (HPC), an annular combustor, a 2-stage high-pressure turbine (HPT), a 5-
stage low-pressure turbine (LPT), an accessory gearbox (AGB) assembly, and
accessories.
The 14-stage HP compressor turns the 2-stage LP turbine (same shaft) until
10600 rpm. The 5-stage LP compressor turns the 5-stage LP turbine to 3600 rpm, using
the gear box the rotation speed is reduced at 3000rpm and it is transferred to the
generator.
2.1 BOP Systems;
2.1.1 Water Treatment Plant; It consists of two identical demineralized water
production lines; one main and one stand by, with capacity 30m3/h each. In case of
emergency situation both lines can operate in parallel with maximum production of
60m3/h of demi-water.
The quality of demineralized water that it is produced should satisfy the
following limitations; SILICATE < 100 ppb, CONDUCTIVITY < 1 µS/cm
Main Equipment (each line consist of):
o Active Carbon Filter
o Cation Resin Filter
o CO2 De-gasifier
o Anion Resin Filter

2.1.3 Fire Protection System; It consists of one Diesel pump, one Electrical
pump and one Jockey pump. Moreover, demineralized water is used as
mean for the fire protection of the transformers, so there is installed
another set of the same pumps for that purpose.

2.1.4 Liquid Fuel System (Diesel); Power Plant is designed to use both gas
as primary fuel or diesel as secondary fuel for power production. The
diesel fuel is stored on site at the storage tank (2500m3). The diesel fuel
should pass through a centrifugal separator (ALFA LAVAL) before it is
stored to the daily tank (500m3) that feeds the units using an installation of
feeding pumps and filters.

2.1.5 Gas Regulation Station (GRS); It is where the pressure and the
temperature of the gas fuel regulated and filtered. It consists of two lines;
the main line has a regulator and the stand by line has no regulator. In
GRS also it is installed the gas compressor which is needed to increase
the gas pressure at the inlet of each unit to 46 bar.

2.1.6 Hot Water System; It consists of two gas fuel boilers (2x100% capacity).
They can operate in parallel when ambient temperature is very low. Hot
water boilers supply hot water to the RMS in order to warm the gas that
feeds the units and also feeds the anti-icing system of unit 3 with hot
water.
