Materials Issues For Users Of Gas Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Material issues are of paramount importance for the reliable and
cost effective operation of gas turbine engines. Because of the high
turbine temperatures, the materials degrade over time, which
requires their repair ...
Fatigue Damage Of Steam Turbine Blade Caused By Frequency Shift Due To Solid Buildup - A Case Study.
(Texas A&M University. Turbomachinery Laboratories, 1994)
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 ...
Field Testing Of Gas Turbine Driven Centrifugal Compressor Packages - Test Procedures And Measurement Uncertainties.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Field testing of gas turbine compressor packages requires the
accurate determination of efficiency, flow, head, power, and fuel
flow in sometimes less than ideal working environments.
Nonetheless, field test results ...
Application Of Dry Gas Seals In Special Purpose Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Noncontacting dry gas mechanical face seals are being routinely
applied to steam turbines to reduce new construction project costs
and improve overall plant operating efficiencies. Historically, most
of the applications ...
Confirming Centrifugal Compressor Aerodynamic Performance Using Limited Test Data Combined With Computational Fluid Dynamic Techniques.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Facing increased market demands for improved aerodynamic efficiency, centrifugal compressor manufacturers must be able to predict and quote the best performance available from the machinery they produce. Confidence in these ...
Acoustic Fatigue Involving Large Turbocompressors And Pressure Reduction Systems.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Much work has been done over the years to predict the potential
for acoustic fatigue in piping systems associated with pressure
reducing systems in the design stage. However, an easily usable
screening criteria for ...
Increased Reliability And Reduction In Long Term Cost Of Ownership Through Proper Spare Rotor Storage, Inspection, Documentation, And Tracking.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Recently, a major chemical company put together a project to
specifically address the repetitive corrosion problem experienced
on the long term storage of critical rotors in a Texas facility.
However, as the strategy ...
Field Performance Testing Of Gas Turbine Driven Compressor Sets.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Field testing of gas turbine compressor packages requires the accurate determination of efficiency, flow, head, power, and fuel flow in sometimes less than ideal working environments. Nonetheless, field test results have ...
Redesign Of Large Steam Turbines For Increased Reliability.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Two similar large steam turbines in an ethylene plant are profiled. One drives the cracked gas compressor train and the other
drives the propylene refrigeration compressor. The two machines are similar and this paper ...
Retrofitting A Large Steam Turbine With A Mechanically Centered Squeeze Film Damper.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Reviewed is the application of a squeeze film damper to a large
steam turbine that addresses high vibration passing through the
first critical speed. The turbine was the fifth near identical machine
purchased over the ...
