Utility Steam Turbine Brush Seals

Engineered for Performance

Large utility steam turbine applications pose one of the most challenging applications to implement a brush seal. These machines often require a system-level engineering approach that includes the evaluation of rotor-bearing system dynamics, rotor system heat stability, structural integrity of components, brush seal performance, startup and shutdown performance, and compact installation concepts.

The engineering expertise and in-house analytical tools at Waukesha Bearings enable us to provide comprehensive engineering studies to tackle such challenging applications.

Installation Locations

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

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