Blackstone completed a minor overhaul of a Turbodyne UE-18479 steam turbine (the driver of the train). This task was part of a larger outage, which included the same crew completing a major overhaul on a Dresser Clark 74-5B vertically split centrifugal compressor (the driven machine in the train).

Scope of Work

  • Complete “as found” alignment
  • Complete “as found” measurements (lift checks, axial float, oil baffle clearances, etc.)
  • Complete Drive End and Non-Drive End bearing inspections and record clearances (replaced NDE bearing due to damage)
  • Reassemble turbine and complete “as left” measurements (lift checks, axial float, oil baffle clearances, etc.)
  • Remove and disassemble governor linkage for modification
  • Replace cam follower bearings
  • Rebuild and reinstall power cylinders
  • Record “as left” cam follower gaps and trip paddle clearance
  • Adjust turbine linkage system

Customer Benefits

  • Peace of mind knowing that their turbine would run flawlessly until the next maintenance overhaul
  • Customer received a comprehensive Technical Report outlining all of the “as found” and “as left” measurements and condition of the turbine
