4 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 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 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; Water Treatment Plant; It consists of two identical demineralized water production lines; one main and one stand by, with capacity 30m 3 /h each. In case of emergency situation both lines can operate in parallel with maximum production of 60m 3 /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 o o o Active Carbon Filter Cation Resin Filter CO2 De-gasifier Anion Resin Filter - 3 -

6 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 (2500m 3 ). The diesel fuel should pass through a centrifugal separator (ALFA LAVAL) before it is stored to the daily tank (500m 3 ) that feeds the units using an installation of feeding pumps and filters. Alfa Laval Manufacturer Alfa Laval Mid Europe GmbH Model Focus Type D Glinde Year of Manufactured 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. Fuel Gas Compressor Motor Voltage V Power kw Speed rpm Manufactured Year 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.
