Compressor Discharge Pipe Failure Investigation With A Review Of Surge, Rotating Stall, And Piping Resonance.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Rotating stall, even with multiple cells, can contribute to piping excitation due to acoustic energy traveling down the pipe as a plane wave. The main objective of the paper is to describe causes and solution of fatigue ...
Rotordynamic Tests Of A Flexible Rotor On Flexure Pivot Journal Bearings And Stability Correlation With Frequency Dependent Characteristics.
(Texas A&M University. Turbomachinery Laboratories, 2002)
A series of performance, unbalance response, and stability tests were performed on a flexible rotor incorporating two flexure pivot tilt-pad journal bearings, followed by a theoretical correlations using synchronous and ...
Engineering Fundamentals Of Multi-MW Variable Frequency Drives - How They Work, Basic Types, And Application Considerations.
(Texas A&M University. Turbomachinery Laboratories, 2002)
A brief historical overview of the conversion from mechanical systems to electrical systems at low power levels is presented to gain an understanding of what is occurring at multiple megawatt (MW) power levels in industry. ...

New Technologies Of Synthesis Gas Compressor Drive Steam Turbines For Increasing Efficiency And Reliability.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Recently, synthesis gas compressor drive steam turbines have required upgrading to increase efficiency and reliability for saving both operation and maintenance costs in many ammonia plants. This paper introduces the latest ...
Compressor Seals For Hydrogen Recycle Service.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Hydrogen recycle service has presented a special challenge for centrifugal compressors and particularly the casing seals. Typical problems include the presence of liquids (condensables and water), hydrogen sulfide, chlorides, ...
Troubleshooting Turbine Steam Path Damage Mechanisms.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Steam path damage, particularly of rotating and stationary blading, has long been recognized as a leading cause of steam turbine unavailability for large fossil fuel plants worldwide. Turbine problems cost the utility ...
Dry Gas Seal System Design Standards For Centrifugal Compressor Applications.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Dry gas seals have been applied in process gas centrifugal compressors for more than 20 years. Over 80 percent of centrifugal gas compressors manufactured today are equipped with dry gas seals. Despite the 20-year trend ...
