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 ...
Mechanical Drive Turbine Control Systems For The 1980's
(Texas A&M University. Gas Turbine Laboratories, 1979)
The changes encountered in moving from mechanical to electrical control of mechanical drive steam turbines are reviewed with regard to both operation and performance. This paper examines past practices in control system ...
Selection And Design Of Tilting Pad And Fixed Lobe Journal Bearings For Optimum Turbo Rotordyanmics
(Texas A&M University. Gas Turbine Laboratories, 1979)
Current trends in bearing designs for turbomachinery are reviewed in terms of manufacturing tolerances and overall design considerations. Discussion of both fixed bore and tilting pad bearings with regard to forced response ...
High Speed And Large Capacity Compressor-Driving Turbines For Chemical Plants
(Texas A&M University. Gas Turbine Laboratories, 1978)
This paper gives a brief description of compressor-driving steam turbines for use in chemical plants. Turbines used for ethylene plants, ammonia plants and LNG plants, in particular, are large-capacity, high-speed ...
Design Automation Of Centrifugal Compressors
(Texas A&M University. Gas Turbine Laboratories, 1978)
Centrifugal compressors used in various plants come in diverse specifications with regard to capacity, pressure and gas handled. In designing such compressors, important considerations are to shorten design time and save ...
