The Power of Yes

Can GE grow the efficiency of my steam plant?

YES. For more than a century, we have engineered and manufactured the latest technologies to provide highly efficient and reliable steam turbines for fossil, nuclear, and renewable applications. GE has supplied more than 30% of the world’s installed steam turbine capacity and 50% of the nuclear steam turbines, which are collectively generating more than 1,200 GW of power.

Advanced technology

Pioneering steam turbine features that have become industry standards

GE’s steam turbine platform offers a broad product portfolio of solutions that accommodate a wide range of site conditions, operational needs, advanced steam cycles, and applications. Our steam turbines share common features and components that enhance the reliability, efficiency, and availability of your plant.

Turbine ARABELLE 1750 mw

Steam turbine welded rotors

Introduced in 1930, our welded rotor technology has stood the test of time, with no ruptures reported in our large diameter steam turbine rotors-manufactured by welding together separate smaller forgings. This allows for:

  • Appropriate forging material selection, based on temperature level at each section of the steam turbine
  • Stress reduction during thermal transients for faster and more frequent load cycling capability
  • Better access for ultra-sonic testing equipment, resulting in higher reliability

Shrink ring design

  • Appropriate forging material selection, based on temperature level at each section of the steam turbine
  • Stress reduction during thermal transients for faster and more frequent load cycling capability
  • Better access for ultra-sonic testing equipment, resulting in higher reliability

Advance blading on GE steam turbines

Innovative blading technology is apparent in our:

  • Modern, three-dimensional profile that results in higher steam power 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

Low pressure module large last stage blades

Our enhanced last stage blade portfolio for steam turbines offers:

  • Dense staggered last stage blade sizes for project specific cold-end conditions and increased steam turbine efficiency
  • A robust module with stress-enhanced grooves and blade attachments for higher turbine reliability

Single bearing efficiency

Our multi-casing steam 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
