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.
