Application Of A Heat Barrier Sleeve To Prevent Synchronous Rotor Instability.
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper explains how synchronous rotor instability can occur
in high speed turbomachinery due to differential heating of bearing
journals. Theoretical investigations have indicated that rotors
supported by fluid-film ...
High Speed Oil-Free Turbomachinery String.
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper is a discussion of the design, manufacture, test, and
field operation of a totally oil-free string of rotating equipment. The
turbomachinery string consists of a multistage centrifugal
compressor driven by a ...
Vibration And Eccentricity Measurements Combined With Rotordynamic Analyses On A Six Bearing Turbine Generator.
(Texas A&M University. Turbomachinery Laboratories, 1998)
This lecture discusses how the vibration characteristics and
eccentricity measurements were combined with rotordynamic
analyses to help improve the reliability of a turbine generator unit.
It also explains certain ...
Design Modifications And Active Balancing On An Integrally Forged Steam Turbine Rotor To Solve Serious Reliability Problems.
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper describes the design modifications and active
balancing on a 19,000 hp integrally forged steam turbine rotor to
improve its dynamic characteristics and reliability. The turbine was
purchased as a replacement ...
Starter Motor Sizing For Large Gas Turbine (Single-Shaft) Driven LNG Strings.
(Texas A&M University. Turbomachinery Laboratories, 1998)
The purpose of this paper is to describe how computer
simulation was used to size the main starter motors for single shaft
gas turbine driven compressor strings used in a large LNG plant.
The paper describes how the ...
Root Cause Analysis Of A Long Term Reliability Problem With Reciprocating Compressors In H2 Service.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Three large reciprocating compressors in H2 makeup service had
been a chronic reliability problem for 30 years. Unit revisions
greatly compounded this issue by eliminating builtin spare
capacity. A Root Cause Analysis ...
Thermal Comfort Study in a Naturally Ventilated Residential Building in a Tropical Hot-Humid Climate Region
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
This paper presents a thermal comfort study in a
naturally ventilated residential building located in a
tropical hot-humid climate region. The specific
objective of this study is to investigate whether
thermal comfort in ...
Owner's Guide to Understanding Methods and Terms of Performance Contracting
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
Performance Contracting is a method of making
improvements to a facility and using the savings
produced by the improvements to pay for the work
over a period of time, typically five to ten years.
Energy Conservation Measures ...
