1 x Frame 6B combined cycle Power Plant

History

Power plant was erected in 1994 and had the first commercial operation in February 1995.

Power plant will remain in stand by operation up to end of October 2010 (available to the local grid only for peaking expected during summer 2010), date when the plant should go out of operation, be de-commissioned and available for sale.

Brief description of main features

1 x GE Gas Turbine model Frame 6B

Frame 6B already incorporates latest GE upgrading packages like: upgraded brush seals for better efficiency, higher firing temperature for increased power output, upgraded IGV, Extendor Kit on combustion components to optimize maintenance and extend inspection intervals.

Gas Turbine Combustion system is Dual Fuel (Natural Gas + Distillate Oil).

Starting System is based on Electric Motor.

At date Frame 6B Gas Turbine accumulated 110.538 Firing Hours.

Second major Inspection to the Gas Turbine was completed last year.

45 MVA Alstom Generator (for GT), model T190 – 240. Spare stator for this generator is available at stock.

Mark V Control System.

Emission control by Steam injection on gas turbine: at 15°C ambient temperature, with GT full power output around 40 MW and about 2 Kilogram / sec of steam injection, emission levels are roughly:

80 to 90 ppm of Nox
1 to 1,5 of CO

Present owner confirms that the gas turbine already completed the second major overhaul before the end of commercial operation.

1 x 23 MW Ansaldo Steam Turbine, model CDI 635 R

1 x 23 MVA Alstom Generator (for ST), model GSCR – 1000 Z4

Steam turbine accumulated 108.906 firing Hours.

DCS Control System for thermal plant (boiler and steam turbine)

ST cross section is reported below:

2 x Gas Compressors

Power Plant is also equipped with two alternative compressors model 2HM/1, for natural gas: one compressor able to boost the pressure from the 11 - 12 bars of the pipeline up to 19,5 Bars required for the correct operation of the gas turbine.

Second compressor works in stand by mode, to replace the first in case of failure or maintenance. If both compressors work simultaneously, they are able to boost gas pressure from 5 bars up to 19,5 Bars. Below pipeline pressure of 5 Bars, the two compressors trip.

Both Compressors are powered by electrical motors.
