-
(Texas A&M University. Turbomachinery Laboratories, 1982)This paper is intended to familiarize people, who are responsible for rotating equipment, with options in blade designs. The information is meant to be helpful in conjunction with blade specifications, design reviews, ...
-
(Texas A&M University. Gas Turbine Laboratories, 1975)This paper is meant to help with failure investigation, presenting a review of the causes and effects involved when blades fail. Included are descriptions of failure mechanisms (stress; resonance; environment) and of the ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)This tutorial paper discusses the basics of corrosion, steam and deposit chemistry, and turbine and steam cycle design and operation - as they relate to steam turbine problems and problem solutions. Major steam turbine ...

-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Overhaul intervals Maintenance practices Solid particle erosion Contract versus in-house maintenance Mechanical driver turbine issues - design et al Steam path repairs Turbine casing and alignment issues Steam turbine ...
-
(Texas A&M University. Turbomachinery Laboratories, 1984)This paper presents some recent technical innovations to improve mechanical drive steam turbine efficiency and presents a case study of a recent retrofit application of these features to a compressor driver. Various external ...
-
(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 ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)This is a case study of a new steam turbine installation in which pipe strain became an issue after commissioning and start-up. This case study will bring light to the use of shaft indicator movement vs. turbine casing ...
-
(Texas A&M University. Turbomachinery Laboratories, 2009)This is a case study of a new steam turbine installation in which pipe strain became an issue after commissioning and start-up. This case study will bring light to the use of shaft indicator movement vs. turbine casing ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Rubs in steam turbines can be especially difficult to diagnose because the vibration signature can manifest differently depending on the location, severity, rotordynamics, machine design and bear similarities to other ...
-
(Texas A&M University. Turbomachinery Laboratories, 1997)There are currently no-or at best, very limited-industry guidelines or requirements on which to quantify the risk associated with turbine inspection intervals. Insurance industry data indicate that steam turbines are a ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)This 15 MW steam turbine/gearbox/4-pole generator train, following a recent overhaul, was showing unusual phenomenon of high level 0.9X vibration during shutdown, as well as power limits due to vibration level increase. ...
-
(Texas A&M University. Turbomachinery Laboratories, 1985)Storage preservation of machinery makes economic sense fur as yet uncommissioned as well as temporarily deactivated ("mothballed") machinery. Storage preservation herein is divided into three main elements: turbomachinery ...
-
Strategies to Prevent Sudden Catastrophic Compressor Failures During Transient Operating Conditions (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Stray currents manifest in rotating machinery as a result of specific abnormalities in machines related to flux imbalance, residual magnetism, electrostatic build-up and induced voltages. Discharges of these voltages in ...
-
(Texas A&M University. Turbomachinery Laboratories, 1997)The LcR ultrasonic technique is ideally suited for stress measurement, since it is a bulk longitudinal wave that propagates just underneath the surface of the item being inspected. Additionally, it is most sensitive to ...
-
(Texas A&M University. Turbomachinery Laboratories, 1983)The disks and shafts of large steam turbines are subject to cracking from a variety of causes that may limit the service life of the rotor. These mechanisms include thermal-mechanical (low-cycle) fatigue resulting from ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)This case study demonstrates the steps taken to solve a structural resonance issue on a VFD driven vertical pump installed in the field. Topics discussed include problem validation, steps taken to solve the issue, the ...
-
(Texas A&M University. Turbomachinery Laboratories, 2007)Variable speed inverter motors are increasingly being used to drive compressors for petroleum, chemical and gas industry services. In the past, as this type of application of large inverters, it has been possible to apply ...
