On Fuel Suitability For Gas Turbines.
(Texas A&M University. Turbomachinery Laboratories, 2004)
Industrial gas turbines allow operation with a wide variety of gaseous and liquid fuels. To determine the suitability for operation with a gas fuel system, various physical parameters of the proposed fuel need to be ...
Development Of Abradable And Rub Tolerant Seal Materials For Application In Centrifugal Compressor And Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 2004)
The use of abradable and rub tolerant polymer seals to reduce leakage between rotating and stationary members in centrifugal compressors and steam turbines has increased over the years. Abradable materials such as mica-filled ...
Life Cycle Cost Assessment Of Turbomachinery For Offshore Applications.
(Texas A&M University. Turbomachinery Laboratories, 2004)
This paper describes a comprehensive life cycle cost (LCC) analysis procedure, regarding turbomachinery systems for offshore oil and gas production platforms. The LCC analysis includes the development of a cost breakdown ...
Changing And Controlling The "First Critical Speed" Of Overhung Centrifugal Fans.
(Texas A&M University. Turbomachinery Laboratories, 2004)
Nine 150 hp centrifugal fans with overhung 40 inch diameter wheels pull hot air through the spray dryer bag houses (SDBH) in the finishing area of a titanium dioxide (TiO2) plant in New Johnsonville, Tennessee. The fans ...
New Technique For Online Washing Of Large Mechanical-Drive Condensing Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 2004)
To compete in today’s economic climate, petrochemical plants are strategizing on continuous long-term operation to reduce maintenance costs and increase productivity. This strategy has led some plants to go from eight years ...
High Pressure Oil-Injected Screw Gas Compressors (API 619 Design) For Heavy Duty Process Gas Applications.
(Texas A&M University. Turbomachinery Laboratories, 2004)
Oil-free screw compressors have been used for process gas application since the 1970s. Oil-flooded screw compressors have been used in many process related applications since the 1980s. Inclusion of oil-flooded screw ...
Transferring Custody Of In-Service Turbomachinery - What Sellers And Buyers Should Consider.
(Texas A&M University. Turbomachinery Laboratories, 2004)
Purchasing used machinery and custody transfer of in-service turbomachinery opened new vistas in the realm of process and utility industries. Turbomachinery engineers have to gear up to handle the challenges posed in ...
Cooling And Lubrication Of High-Speed Helical Gears.
(Texas A&M University. Turbomachinery Laboratories, 2004)
Centrifugal compressor and turbine manufacturers are building machines that operate at increasingly higher speeds to reduce the size and cost of their equipment. Helical gears are commonly used to step down the speed of ...
Probabilistic Life Assessment Of An Impeller With Discontinuities.
(Texas A&M University. Turbomachinery Laboratories, 2004)
This paper discusses and presents a probalistic method to evaluate the useful life of an impeller with material imperfections. These discontinuities may be on the surface or subsurface. The method combines linear elastic ...
Low Frequency Instability In A Process Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2004)
A catalytic gas process compressor experienced low frequency vibrations in excess of trip levels following installation of a honeycomb balance piston. After 12 years of operation, low seal oil differential forced an unplanned ...
