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, ...
Turbomachinery Vision - 2000 (Getting the Most out of What You Got).
(Texas A&M University. Turbomachinery Laboratories, 2000)
The Historical Evolution Of Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 2000)
This paper presents a comprehensive treatise of the antecedents, evolution, developments, and inventions relating to turbomachinery from early paddle wheels to modern turbojets emphasizing the constant challenge, failures, ...
Low Emissions Combustion Technology For Stationary Gas Turbines Engines.
(Texas A&M University. Turbomachinery Laboratories, 2000)
The need to control exhaust emissions from stationary power sources is dictated by environmental regulations that limit the amount of smoke (particulates), sulfur dioxide, carbon monoxide, hydrocarbons, and oxides of ...
Rod Drop Monitoring, Does It Really Work?.
(Texas A&M University. Turbomachinery Laboratories, 2000)
In 1994, the Twenty-Third Turbomachinery Symposium featured the first session of Discussion Group 12, “Reciprocating Compressors.” Each year since its inception, there has been one consistent discussion topic brought up ...
Torsional Vibration Analysis Of Synchronous Motor-Driven Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 2000)
One of the foremost concerns facing turbomachinery users today is that of torsional vibration. In contrast to lateral rotordynamics problems, torsional failures are especially heinous since the first symptom of a problem ...
