Using Modified Acoustic Emission Techniques For Machinery Condition Surveillance
(Texas A&M University. Gas Turbine Laboratories, 1978)
Acoustic emission is the release of high frequency sound energy in a material under strain. It is the result of microscopic changes in material structure and is associated with deformation and defect growth. Until about ...
Practical Design Solutions For Mechanical Drive Steam Turbines
(Texas A&M University. Gas Turbine Laboratories, 1976)
Following a review of possible alternative solutions regarding the choice of a mechanical driver; i.e., electric motor, gas turbine or steam turbine, it is demonstrated that the steam turbine as applied in industry is ...
Advanced Research Programs In Turbomachinery
(Texas A&M University. Gas Turbine Laboratories, 1976)
The objective of this paper is to acquaint the reader with the developments in the field of turbomachinery. The research conducted at the Gas Turbine Laboratories has two primary goals. First, to improve the efficiency of ...
Problems Encountered In Boiler Feed Pump Operation
(Texas A&M University. Gas Turbine Laboratories, 1976)
Although mechanical and hydraulic instabilities in centrifugal pumps caused a considerable amount of problems for large Nuclear and Fossil Generating Stations influencing "Power Plant Availability," a relatively limited ...
Efficiency In Mechanical Drive Steam Turbines
(Texas A&M University. Gas Turbine Laboratories, 1976)
With cost of energy in the $2.00 per 10^6 BTU range throughout the Western Industrialized World, the current value of one horsepower over a five-year period is in excess of $600. This high energy valuation is of relatively ...
Distortion Of Speed Changer Housings And Resulting Gear Failures
(Texas A&M University. Gas Turbine Laboratories, 1976)
Gear case distortion due to thermal effects has caused unique and costly failures at several of Union Carbide's process plants. The unusual nature of these failures has prompted us to make an in-depth logical investigation ...
Metal Diaphragm Coupling Perfomance
(Texas A&M University. Gas Turbine Laboratories, 1976)
The performance of a Metal Diaphragm Coupling is to a large extent determined by its endurance limit. The endurance limit can be estimated by calculations but must be confirmed through testing. The author cites data obtained ...
Control of Sulfur Dioxide Emissions from Pulverized Coal-Fired Boilers by Dry Removal with Lime and Limestone Sorbants
(Energy Systems Laboratory (http://esl.tamu.edu), 1979)
Over the past decade increasing concern over the potential environmental impact associated with the emissions of both gaseous and particulate pollutants has resulted in the promulgation of strict regulatory standards ...
Constrained Optimization Technology Based on Synthesis Concepts for Solving Complex Heat Recovery Problems
(Energy Systems Laboratory (http://esl.tamu.edu), 1979)
Simulation of complex heat recovery systems such as crude preheat trains using computer tools is now widely practiced. ChemDesign, Inc. has developed a computer tool which can perform this calculation but is also capable ...
Design Considerations for Industrial Heat Recovery Systems
(Energy Systems Laboratory (http://esl.tamu.edu), 1979)
High quality energy exhaust streams from U. S. industrial plants are estimated to have an energy equivalent of 2 to 3 million barrels of oil equivalent per day, or about 15% of total industrial energy consumption. The value ...
