The New Standard
The world’s first G Series turbines are also among the world’s best-performing turbines. Mitsubishi’s M501G (267MW, 60Hz) and M701G (334MW, 50Hz) achieve the highest inlet temperatures (~1500° C) and the highest efficiencies in their class.
Based on proven F Series technologies, Mitsubishi’s G Series turbines incorporate a wide range of design enhancements, including an improved compressor design, steam-cooled combustor, advanced internal cooling schemes for better cooling effectiveness of airfoils and advanced seals to prevent secondary losses.
