Improve performance

• Our generators are optimized for up to 98.9% efficiency, with world-class stability during load changes and flexible operation. They are designed for a service life of 10,000 start/stop cycles, making them a cost-effective alternative to hydrogen-cooled or water-cooled generators for industrial applications up to 370 MVA.

Single bearing design

• Avoidance of load shifting for higher reliability.
• Efficient shaft alignment for reduced installation time.
• Shorter overall turbine shaft length for lower building costs.

Advanced sealing features

• Shaft and tip brush seals, developed in conjunction with our global research organization, improve leakage control when compared to more conventional sealing technology.
• Abradable coatings on stationary seals enable the reduction of radial clearances, decreasing long-term performance degradation.

High-efficiency last-stage blades

• Densely staggered last-stage blade sizes for project-specific cold-end conditions and increased efficiency—up to 60’’ for 50Hz and up to 50” for 60Hz.
• Robust blade-to-rotor design with high cyclic life capability for high reliability and availability.
• Features such as full tip shroud, enhanced tip section with low shock loss, aerodynamic part span connector, and increased root-reaction improve steam turbine generator performance.
• Advanced radial vortexing improves performance and hood integration over a range of loads.
• Industry-leading backpressure capability allows for smaller air-cooled condensers, lowering overall plant cost.

Advanced blading

• Modern, three-dimensional profile design that results in higher efficiency.
• High pressure (HP), intermediate pressure (IP), and low pressure (LP) front stage blades that are milled from a single forging for excellent mechanical integrity and higher reliability.
