  • Applying Steam Turbines For Pump Drives (.pdf)
    losses. This can make the turbine a good choice for marginal NPSH applications as it can avoid drastic speed reductions. When operating at low speed, turbines reduce radial reaction in centrifugal pumps operating at low flows. TP002 TP002. APPLYING STEAM TURBINES FOR PUMP DRIVES. John Elmore
  • Condition Monitoring of Steam Turbines by Performance Analysis
    this leakage explained observed poor performance on two sets. Key Words: condition monitoring; optimisation; plant performance; predictive maintenance; steam turbines; testing; N2 packing INTRODUCTION Steam turbine generators are reliable machines, and often operate continuously for many months
  • Wet-Steam Turbines for Nuclear Power Plants
    Wet-Steam Turbines for Nuclear Power Plants. Presenting a survey of modern wet-steam turbines, this book explains in clear, but detailed language the design features of the world s leading wet-steam turbine manufacturers, including the subtleties of operation of these complex components.

  • Bolt Expansion Job on a Steam Turbine
    – ‘Hottopics’EventsPress releasesTechnical articlesNews archive Home / News / News archive / Boltexpansion. Bolt heating on a steam turbine. The use of induction heating for bolt expansion in high-pressure turbines is a powerful business tool. This case story from Italy illustrates the benefits --speed
  • Optimization of a Leading Edge Groove Tilting Pad Journal Bearing for Application in a Small, High Speed Multi-Stage Steam Turbine (.pdf)
    Optimization of a leading edge groove tilting pad journal bearing for application in a small, high speed, multi-stage steam turbine is described. Rotordynamics constraints to meet a design objective maximum operating speed of 18,000 rpm resulted in a rotor with a 5 1. 0 in. bearing span and 5. 0
  • Fatigue Damage of Steam Turbine Blade Caused by Frequency Shift Due to Solid Buildup-A Case Study (.pdf)
    The case history is presented of a large steam turbine that experienced blade damage after about eight years of service. The probable cause and subsequent solution to the problem are addressed. A discussion of the metallurgical analysis of the damage, Campbell diagram, SAFE diagram and modal test
  • Steam Turbine Water Washing (.pdf)
    Capability for full speed turbine water washing has become an increasing requirement, especially on mechanical drive units. Although load carrying capability will be somewhat reduced, essentially the overall plant requirements are maintained.
  • MR Steam Turbine Material Accelerator
    After completing installation of a fresh 2250 hp motor on the Fructose MR, initial quality check vibration readings showed a significant .17g spike at 2X line frequency (120hz) in the gse spectrum. This is indicative of rotor-stator rotation eccentricity. There was also a 1X spike in the ips
  • Performance Acceptance Testing of Steam Turbines (.pdf)
    Test details should be considered early in the plant planning process if a formal acceptance test is being considered. Dresser-Rand ST Technology Reports show the various measurements and instrumentation required for each specific thermodynamic cycle. Performance Test Codes and reports published by
  • Frequency Evaluation of a Steam Turbine Bladed Disk (.pdf)
    Unplanned and untimely shutdowns of critical turbomachinery is costly-for both the user and the original equipment manufacturer. Therefore, it is very important that the turbomachinery be designed and operated to assure trouble-free operation. This is not always easily accomplished. Because
