Options for Generating Steam Efficiently
(Energy Systems Laboratory (http://esl.tamu.edu), 1996-04)
This paper describes how plant engineers can efficiently generate steam when there are steam generators and Heat Recovery Steam Generators in their plant. The process consists of understanding the performance characteristics ...
Benchmarking Process Energy Performance From Historical Data: Bringing Sanity into Energy Budgets
(Energy Systems Laboratory (http://esl.tamu.edu), 1996-04)
Reducing energy costs has two components: knowledge of process energy consumption and an energy management process. This concept is summed up in energy management's 2-M rule: to manage energy, energy must be measured. After ...
Low-Value Waste Gases as an Energy Source
(Energy Systems Laboratory (http://esl.tamu.edu), 1996-04)
Waste gases with potentially useful fuel value are generated at any number of points in refineries, chemical plants and other industrial and commercial sites. The higher quality streams have been utilized successfully in ...
On-Site Diesel Generation- How You Can Reduce Your Energy Costs
(Energy Systems Laboratory (http://esl.tamu.edu), 1996-04)
Interruptible power rates, Utility special rate negotiations, and the emergence of a spot electrical power market all can lead to lower industrial energy costs. The installation of low cost on-site diesel powered generation, ...
Approaches Toward Achieving Optimum Efficiency in Rerates of Large Centrifugal Compressors
(Energy Systems Laboratory (http://esl.tamu.edu), 1996-04)
Centrifugal compressors are commonly used within the process industries as prime movers. For many years, plants have been designed with "single train", unspared, major machinery in order to reduce construction, operating, ...
Turbine Instability Solution-Honeycomb Seals.
(Texas A&M University. Turbomachinery Laboratories, 1996)
A 40,000 hp steam turbine-generator in a utility service experienced a history of high vibration alarms and trips from an online vibration monitoring system. The excursions of high vibration restricted the operational load ...
The Design, Application, And Operation Of High Efficiency Turboexpanders In Process Plants.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Turboexpander thermal efficiency is an important parameter in the process design of hydrogen purification plants. When a process requires low flow and high head, expander thermal efficiency can only be improved by increasing ...
Profiled Leading Edge Groove Tilting Pad Journal Bearing For Light Load Operation.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Optimization of a leading edge groove tilting pad journal bearing for application in a small, high speed, multistage steam turbine is described. Rotordynamics constraints to meet a design objective maximum operating speed ...
Squeeze Film Damper Bearing Experimental Vs Analytical Results For Various Damper Configurations.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Higher speeds, longer shafts, and increased power has made squeeze film damper (SFD) bearing performance increasingly more important to control both synchronous and subsynchronous fibration in rotating machinery. SFD bearing ...
Practical Design Against Torsional Vibration.
(Texas A&M University. Turbomachinery Laboratories, 1996)
One of the foremost concerns facing turbomachinery users today is that of torsional vibration. In contrast to lateral vibration problems, torsional failures are especially heinous since the first symptom of a problem is ...
