1 COMBINED NATURAL GAS POWER PLANT

2 POWER PLANT LAYOUT

3 OFFERING TO SELL ; - 6 ALSTOM Power Plant U.K. construction TYPHOON model gas turbines ( 5.08 MW ) - 1 ALSTOM Power s.r.o. construction ST3- C.V56 steam turbine ( Nom ; MW, Max: 16.3 MW ) - Build in 2003 and has been active since - Maintenance of the turbines are carried out by Siemens - 2 Boilers (heat recover steam generators) - 7 ALSTOM power transformers - Two bus-bar systems (34,5 kV) - Air filtering system for effective performance in polluted enviroments - The facility works with 43% efficency and has a total capacity of 45 MWh.

4 GAS TURBINES (6)

5 Technical Data of the Turbines (6) SGT-100-1S single-shaft turbine for Power Generation Power output 5.25 MW(e) Fuel: Natural gas / liquid fuel / dual fuel and other fuels capability on request Automatic changeover from primary to secondary fuel at any load Frequency: 50/60Hz Electrical efficiency: 30.5% Heat rate: 11,815kJ/kW-hr (11,199Btu/kW-hr) Turbine speed: 17,384rpm Compressor pressure ratio: 14.6:1

6 STEAM TURBINE (1)

7 Technical Data of the Steam Turbine (1) TURBINE : ALSTOM Brno/ Czech Repuplic TYPE : ST3-C, V56A ATP2 (Condensing) TURBOSE OUTPUT: (at generator terminals ) Rated:15,25 MW maximal:16,3 MW Speeds :5952 rpm Live steam Pressure : 45 Bar Temperature: 440 C Flow : 52,2 t/h LP admissio steam Pressure : 6 Bar Temperature :243 C Flow :12,6 t/h

8 Heat Recover Steam Generators/Boilers (2)

9 TECHNICAL DATA FOR BOILERS

10 TRANSFORMERS - To increase the output voltages of generators from 11 kV to 34.5 kV, 7 ALSTOM power transformers are used. - Gas turbine's power transformers are 11 / 34.5 kV and 6550 kVA the - The steam turbine transformer is 11/34.5kV and 20,400 kVA power. - In addition, for internal need we have 4 transformers. 2 of them are 0.4 kV / 1000 KVA, the other 2 are 0.4 kV / 1600 KVA power.

11 COOLING TOWERS

12 AIR FILTERING SYSTEM

13 LIQUID FUEL SYSTEM Gas turbines and natural gas alternative-fuel units, can operate with diesel and naphtha fuels. Fuel transitions can take place without interruption. If there is a drop in gas pressure, the liquid fuel passage is provided automatically.

14 PROCESS FLOW OF THE POWER PLANT
