Gas Turbine Performance - What Makes The Map?
(Texas A&M University. Turbomachinery Laboratories, 2000)
The power and efficiency characteristics of a gas turbine are the result of a complex interaction of different turbomachines and a combustion system. This tutorial addresses the basic characteristics of each of the components, ...
Critical Review Of Compressor Impeller Vibration Parameters For Failure Prevention.
(Texas A&M University. Turbomachinery Laboratories, 2000)
One of the most difficult diagnostic problems for centrifugal compressors is fatigue failure of an impeller, especially those with covers. The structure of a covered impeller is inherently resistant to alternating forces ...
Online, Continuous Monitoring Of Mechanical Condition And Performance For Critical Reciprocating Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2001)
This paper outlines the typical problems seen in reciprocating compressors and shows that the existing type of monitoring systems, consisting of vibration level, rod drop, rod runout, and valve cap temperatures, often ...
Short Courses for the Proceedings of the 30th Turbomachinery Symposium
(Texas A&M University. Turbomachinery Laboratories, 2001)
Multiple Resonance Vibration Mitigation On A 54,000 HP Parallel Shaft Double Helical Speed Increaser.
(Texas A&M University. Turbomachinery Laboratories, 2000)
Test stand vibration measurements on a partially loaded 54,000 hp, parallel shaft, double helical speed increaser revealed synchronous resonant vibrations near normal operating speed. Further testing confirmed the lateral ...
Innovative Gas Turbine Performance Diagnostics And Hot Parts Life Assessment Techniques.
(Texas A&M University. Turbomachinery Laboratories, 2001)
Traditional service and maintenance contracts are evolving to new form of relationship between providers and operators requiring deep changes in service offerings, with strong emphasis on high-tech contents. In gas turbine ...
Efficiency Improvements On Large Mechanical Drive Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 2001)
Many of the mechanical drive steam turbines in service in the world today were designed without the demands for optimum efficiency. In order to meet the changing economic requirements that plants face, technological solutions ...
Rotor Instability Problems In An Integrally Geared Compressor Supported By Tilting Pad Bearings.
(Texas A&M University. Turbomachinery Laboratories, 2001)
The appearance of a strong subsynchronous instability in an overhung compressor highlights the fact that rotordynamic instabilities are not restricted to high-pressure multistage between bearing compressors with overhung ...
Improved Steam Turbine Leakage Control With A Brush Seal Design.
(Texas A&M University. Turbomachinery Laboratories, 2001)
Brush seal designs offer improved leakage control over conventional labyrinth seals by applying a compliant bristle with very tight clearance over the rotating shaft. Originally developed for the aircraft engine industry, ...
