124 MW GE PG 6591 Gas Turbine Power Plant

The Advantages of the Frame GE PG 6 Gas Turbine:

  • The GE frame 6 turbine is used worldwide in in a wide range of applications; such as simple cycle, cogeneration, and combined-cycle.
  • The combustion supports low cost gas and liquid fuels, including process gases, low calorific gases, and up to 30 percent hydrogen, 50 percent ethane, 100 percent propane, and 50 percent nitrogen
  • The standard combustion supports heavy oils, naphtha, bioethanol, methanol, synthetic gases, and steel mill gases and capable up to 95 percent hydrogen, or heavy fuel oil with up to 200ppm vanadium
  • The GE frame 6 gas turbine is a heavy duty, rugged, durable and flexible gas turbine that provides long service between 32,000 hour maintenance intervals.

Brief description 124 MW GE PG 6591 Gas Turbine Power Plant

This Combined Cycle Power Plant consists of two (2) 42.3 MW GE PG 6591 Gas Turbines, 39.9 MW GE Steam Turbine, HRSG, Dual Fuel: Natural Gas Fuel or Diesel, 50 HZ, 11.5 KV, Commissioned in 2005, upgrades to the plant in 2012 and 2013. Hours run since major maintenance was performed: 8,000 to 10,000 hrs. Plant is in very good condition and has been very well maintained since new. Plant can be seen running at the time of inspection and all service records can be viewed on site.
