Gas Turbine Design Features
The Most Powerful 60Hz F-Class Gas Turbine in the World
Combustion
Lowest firing temperature in the market:
• Low NOx emissions
• Longer part life
• Conventionally cast turbine material
(no need for single crystal material)
• Wide Wobbe operation
• Sub 9ppm emissions
Compressor
• 13 stages
• 19:1 pressure ratio
High power output on hot days:
• Without peak firing or other power
augmentation
Turbine
• 4-stages
• Conventionally cast parts
Rotor
• Constant rotor cooling air temperature
• Steel discs w/ Hirth serrations
April 1-3, 2014 * Ernest N. Morial Convention Center
4-stage turbine:
• Reliable part life due to lower
aerodynamic loading when compared to a
3-stage turbine at the same power output
Constant rotor cooling air temperature:
• Predictable rotor life regardless of
ambient temperature
• 80 units in simple cycle

Combustion
Fuel Flexible, Reliable, Low Emissions
25 ppm Emissions on Fuel Oil
• “SGT6-5000F sets a new benchmark
in the industry demonstrating 25ppm
NOx emissions on fuel oil.”
• <9 ppm emissions on natural gas
from 40% to 100% GT load
Liquid and Gaseous Fuel Flexibility
• Diesel oil
• Syngas with a wide range of H2 content
• Light crude oils
• Natural gas + H2
• Bio-diesel
• Low-Btu natural gas w/ high N2 content
• Condensates
• Gases with a wide Wobbe Index variation
