Utility Steam Turbine Brush Seals

Utility Steam Turbine Brush SealLarge utility steam turbine applications pose one of the most challenging applications to implement a brush seal. These machines often require a system level transdisciplinary engineering approach that necessitates:

  • The evaluation of rotor-bearing system dynamics
  • Rotor system heat stability
  • Structural integrity analysis of components
  • Brush seal performance
  • Compact installation  concepts

Commonly, three locations of brush seal implementation are considered in utility steam turbines:

  • End-packing seals
  • Interstage shaft seals
  • Turbine bucket tip seals

Waukesha Bearings' engineering experience and breadth of in-house analytical tools enable us to provide comprehensive engineering studies to tackle such challenging applications.
