Impact of Degradation on the Operational Behaviour of a Stationary Gas Turbine and in Detail on the Associated Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
Degradation of stationary gas turbines is a quite often observed burden and can impact financial revenues of end-users significantly. In addition to the well-known occurrence of increased pressure losses in the intake ...
Experimentally Based Statistical Forced Response Analysis for Purpose of Impeller Mistuning Identification
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
A Root Cause Failure Analysis (RCFA) for repeated fourth stage impeller blade failures in a five stage centrifugal propane compressor used in Liquefied Natural Gas service is expanded upon by examining the amount and effect ...
POLYMER SEAL USE IN CENTRIFUGAL COMPRESSORS – TWO USERS’ EXPERIENCES OVER 15 YEARS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
For over 20 years now, the efficiency and reliability of centrifugal compressors has been enhanced by the application of engineered thermoplastic materials to the eye, shaft, and balance piston labyrinth seals. Traditionally ...
Effectiveness of Windage Features on High Speed Couplings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
Following the changes to API 671, there is a requirement
to reduce temperature around guarded coupling designs.
Existing features used in high performance (HP) couplings
involve various methods of shrouding and covering ...
Train Performance - Evaluation and Monitoring by Torque Meter Applications and Process Gas Compressor / Steam Turbine Train Fouling and Washing Mitigation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
The systematic monitoring and evaluation of
turbomachinery is an important diagnostic tool in the execution
of a long-term maintenance plan as well as the prevention of
unexpected outages due to machinery breakdown. ...
