Analysis Of Hot Section Failures On Gas Turbines In Process Plant Service.
(Texas A&M University. Turbomachinery Laboratories, 1999)
In-service failures of process plant gas turbines can have major economic consequences in terms of repairs and downtime. Following such an incident, steps need to be taken to avoid a recurrence. This is best accomplished ...
Improvement Of Centrifugal Compressor Reliability Handling High Pressure And High Density Gas.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Centrifugal compressors handling high pressure and high density
gas can sometimes encounter trouble such as rotor instability and
impeller resonance vibration while in operation. In order to eliminate
these problems, ...
Influence Of Oil Injection Method On Thrust Bearing Performance At Low Flow Conditions.
(Texas A&M University. Turbomachinery Laboratories, 1999)
The advantage of operating a thrust bearing in an evacuated cavity has been well documented in the literature. By draining the
oil from the bottom of the housing and eliminating standing oil around the thrust collar, ...
High Frequency Fatigue Failure In Silencer/Pulsation Dampers For Oil Free Screw Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Oil-free screw (OFS) compressors are capable of producing
high-pressure pulsations in the discharge gas stream, over a
frequency range of 200 to 3000 Hz. The fundamental pressure
pulsation is due to the opening cycle ...
Use Of Metal Bellows Noncontacting Seal And Guidelines For Steam Applications.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Steam turbines are used throughout the process industries and
provide a reliable means of driving pumps, compressors; and other
rotating equipment. Carbon rings are currently the most common
way

Gas Turbine Power Augmentation By Fogging Of Inlet Air.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Gas turbine output is a strong function of the ambient air temperature with power output dropping by 0.3 percent to 0.5 percent for every 1 F rise in ambient temperature. While this characteristic is inherent in any gas ...
Practical Methods For Field Performance Testing Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Detailed performance analysis of centrifugal compressors in the field essential to evaluate their existing condition. The current performance of a compressor can also be a valuable tool in evaluating its reliability. A ...
High Temperature Coatings For Industrial Gas Turbine Users.
(Texas A&M University. Turbomachinery Laboratories, 1999)
High temperature coatings are used for protecting the high temperature turbine components from environmental attack due to
oxidation and hot corrosion. These coatings have developed from simple aluminide coatings to complex ...
Steam Turbine Governing Systems And Electronic Governor Retrofit.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Steam turbine retrofitted governing systems are being designed with today’s technology to operate a turbine in a safe and reliable manner. The design is completed with an extreme amount of effort being concentrated in the ...
Rotordynamic Stability Tests On High-Pressure Radial Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1999)
This paper describes extensive measurements on high-pressure radial compressors with rated discharge pressures of more than 400
bar (5800 psi). The purpose of the measurements was to deterine m the damping behavior of the ...
