Designing Optimal Heat and Power Systems for Industrial Processes
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1988-09)
Industrial heat and power systems are complex and not fully understood as integrated systems. Within the context of the overall manufacturing process, they represent enormous capital investments and substantially contribute ...
Solution Of Subsynchronous Vibration Problems In Radial Flow High-Speed Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Experience, theoretical and practical, investigations are presented on two radial flow high-speed turbines, which showed unacceptable high subsynchronous vibrations during operation onsite. The first example deals with a ...
Experience With Online Condition Monitoring System.
(Texas A&M University. Turbomachinery Laboratories, 1988)
A total online condition monitoring system has been in operation on the world's largest offshore facility located off the coast of Norway. The Ekofisk platforms are operated by the Phillips Petroleum Company Norway and ...
Turbine Protection System Performance.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The need to protect a turbine generator from abnormal operating condidtions is a given. Power plant operational historical data indicate that malfunction of the turbine protection system (TPS) has been the initiator of ...
Operating Experience With Improved Steam Turbine Packing Rings.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The losses in turbine performance due to excessive leakages in the labyrinth seals can result in significant heat rate degradation to the turbine cycle. The modified packing arrangement described helps eliminate the rubs ...
Natural Gas Purchasing Options
(Energy Systems Laboratory, 1988-09)
As a result of economic and regulatory changes, the natural gas marketplace now offers multiple options for purchasers. The purpose of this panel is to discuss short-term purchasing options and how to take advantage of ...
Large Motor Specification and Selection
(Texas A&M University. Turbomachinery Laboratories, 1988)
The induction motor has been the work horse of industry for many years. It has achieved this position by virtue of its ruggedness, and relative low cost. Induction motors include the popular squirrel cage and the versatile ...
Improving Plant Economy Through Retrofit And Maintenance Of Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Retrofits on compressors can become attractive if the operating requirements of a plant change. Often, compressor modifications are imposed by process changes due to market demands or new process technologies. Sometimes, ...
Turbine-Generator Life Assessment/Extension.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The approach and methodology to life assessment/extension are described. Items considered are nondestructive testing, material testing, flaw sizing, stress analysis, fracture mechanics analysis and cumulative damage analysis. ...
Turbomachinery Health Measurement Application And Misapplication
(Texas A&M University. Turbomachinery Laboratories, 1988)
All machinery vibrates, has heat generated internally, and begins to wear as soon as it is put into service. The monitoring process must be customized for each class of equipment. If possible, each machine should be evaluated ...
