Shifting Critical Speeds Out Of The Operating Range By Changing From Tilting Pad To Sleeve Bearings.
(Texas A&M University. Turbomachinery Laboratories, 1993)
One property of heavily to moderately loaded sleeve bearings is the resulting asymmetric stiffness and damping coefficients. These asymmetric properties often result in split first critical speeds. Since the horizontal ...
Safety, Application, And Service Factors As Applied To Shaft Couplings.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Shaft couplings are rated by their manufacturers as to how much torque they can transmit, how much misalignment they can accommodate, and the maximum speed at which they can operate. Still, manufacturers, buyers, or various ...
Energy Conservation Opportunities in Commercial and Industrial Facilities: Energy Utilization Indices (EUI) in Texas LoanSTAR Buildings
(Texas A&M University, 1993-08)
The work described in this report was performed under the direction of the Energy Analysis and Diagnostic Center (EADC) at Texas A&M University. The EADC program is managed by University City Science Center under agreement ...
Saving Energy in Industrial Compressed Air Systems: Issues and Obstacles in DSM Program Design
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
Compressed air systems are among the most common and least efficient electrical end uses in industrial plants. Over 50% of plants use compressed air systems. According to various estimates, between 20% and 35% of the energy ...
Energy Conservation and Efficiency Improvement for the Electric Motors Operating in U.S. Oil Fields
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
Because of its versatility, electricity consumption continues to grow all over the world more rapidly than any other energy form. The portion of the United States' primary energy supply used as electricity has expanded ...
Automatic Tube Cleaning Systems for Condensers & Heat Exchangers
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
Condenser tube fouling contributes up to 50% of the total condenser tube heat transfer resistance. This fouling results in reduced heat exchanger performance, reduced production, increased operational cost, increased back ...
Heat Recovery Steam Generator Simulation
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
The paper discusses the applications of Heat Recovery Steam Generator Simulation. Consultants, plant engineers and plant developers can evaluate the steam side performance of HRSGs and arrive at the optimum system which ...
Insights into Industrial Energy Auditing from the EADC Program: An Academic Perspective
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
Energy auditing as a tool for energy conservation is discussed using insights gained from data gathered from the DOE EADC program over a ten year period. Details about the contents of the database, procedures for it access ...
Adjustable Speed Drives in the U.S. Petroleum Refining, Petrochemical, and Chemical Industries
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
This paper describes applications and incentives for the use of variable frequency drivers (VFD) in the petroleum refining, petrochemical, and chemical industries. VFDs are a particular type of adjustable speed driver (ASD) ...
Cogeneration: An Industrial Steam and Power Option
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
Industrial facilities of all sizes have the ability to reduce and better control both power and steam costs with a cogeneration system. Unlike the larger systems that sell almost all of the cogenerated power to a regulated ...
