Location of Leaks in Pressure Testable Direct Burial Steam Distribution Conduits
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
Central steam is commonly distributed through direct burial lines protected by an outer conduit. These underground conduit systems are subject to electrolytic corrosion. Failure of the outer casing permits water intrusion ...
Demonstration of a Carbonate Fuel Cell on Coal Derived Gas
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
Several studies indicate that carbonate fuel cell systems have the potential to offer efficient, cost competitive, and environmentally preferred power plants operating on natural gas or coal derived gas (“syn-gas”). To ...
Insertion Paddlewheel Flowmeters: An Evaluation After Two Years of Use
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
Insertion paddlewheel flowmeters were removed from field installations after 12 to 24 months of service for inspection and calibration. The tests were designed to identify meter degradation because of scale and debris on ...
Case Studies In Turbomachinery Operation And Maintenance Using Condition Monitoring.
(Texas A&M University. Turbomachinery Laboratories, 1993)
With exceedingly high downtime costs and the need for efficient operation of turbo machinery, integrated condition monitoring, wherein a number of health parameters are analyzed, is becoming increasingly popular in process ...
Magnetic Bearing Retrofit Of A High Speed, Eight Stage Coker Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1993)
The design, integration, and implementation of a successful project to retrofit a high speed, eight stage centrifugal compressor with magnetic bearings and gas face seals is presented. The application is removal of light ...
Critical Speeds And The Importance Of Stiffness - A Case Study In The Design And Testing Of A Large Mechanical Drive Steam Turbine To API Standard 612.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Rotordynamics has long been one of the major considerations in the design of variable speed rotating equipment. Bearing support stiffness is a significant factor in the designer's ability to predict critical speeds and ...
Analysis Of Torsional Vibrations In Rotating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Predicting And Verifying Rerated Compressor Performance Through Single Stage Scale Model And Limited Field Testing.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Performance verification of centrifugal compressor rerates creates a unique challenge to turbomachinery users. It is not often practical to perform flange-to-flange performance tests on machinery already installed in the ...
Hydraulic Removal Of Coupling Hubs - Keyed And Keyless.
(Texas A&M University. Turbomachinery Laboratories, 1993)
In rotating machinery, torque is transmitted from shafts to coupling hubs (or vice versa) through keys, friction, or a combination of the two. As a rule; coupling hubs must be installed on shafts with a certain amount of ...
Test Of Process Turbocompressors Without CFC Gasses.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Increasing restrictions from environmental protection laws will necessitate at least partial substitution of chlorofluorocarbon (CFC) gases still in use today for performance tests of turbocompressors in closed loops. The ...
