Digital Solutions

A World Leader

We have supplied more than 30% of the world’s installed steam turbine capacity—totaling more than 930 GW of power production capability to date in operation.

For more than a century, we have consolidated the best available technology from numerous suppliers into core platforms that support our advanced, innovative, efficient, and reliable steam turbine solutions. GE boasts highly qualified and specialized engineering centers and factories in key markets around the world.

 

Increased Efficiency

Continuous improvements to the water steam cycle are supported by our broad rear stage portfolio.

Our cutting-edge 3D blading platform helps enhance the load grade and customize the flow path for project-specific conditions and increased performance.

High Availability and Reliability

Advanced lifetime assessment procedures reduce maintenance and increase turbine availability.

Our long-term testing program validates material behavior and ensures steam turbine component reliability.

Enhanced Operational Flexibility

Advanced fracture mechanic methods provide reliable lifetime assessment of the steam turbine components and increased cycling capabilities.

An enhanced blade groove design reduces thermal stresses for increased rotor life.

Our steam turbines are also a vital part of GE's "Smarter. Cleaner. Steam Power." initiative.

Advanced Technology 

GE has pioneered many core features that have become steam turbine standards.

Welded Rotors

We introduced our welded rotor technology in 1930. Since then, it’s stood the test of time with no ruptures reported in our large diameter rotors.

This generates:

  • Stress reduction during thermal transients for faster and more frequent load cycling capability
  • Better access for ultra-sonic testing equipment, creating higher reliability

Shrink Ring Design

Our shrink ring design allows for a rotationally symmetric inner casing resulting in: 
 

  • Reduced distortions while maintaining clearances during operation—providing sustained higher efficiency
  • A more compact design with smaller wall thicknesses for flexible load cycling and faster startup times

Single Bearing Design

Our multi-casing turbines have a single bearing between each turbine section for:
 

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

Advanced Blading

Innovative blading technology is apparent in our:
 

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