Redesign Of The Last Two Stages Of A Mechanical Drive Steam Turbine.
(Texas A&M University. Turbomachinery Laboratories, 1998)
A six stage mechanical drive steam turbine rated at 13,300 hp
was installed at a petroleum facility in Texas to drive a multistage
centrifugal compressor used in recycle gas service on a high
pressure hydrogen cracker. ...
Guidelines For Specifying And Evaluating New And Rerated Multistage Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Refineries, petrochemical companies, and gas processors are
continually trying to increase plant production while budgets are
getting tighter. Rerating process centrifugal compressors has
become an ever-increasing trend ...
Gas Turbine Blade Failures - Causes, Avoidance, And Troubleshooting.
(Texas A&M University. Turbomachinery Laboratories, 1998)
With blading problems accounting for as many as 42 percent of
the failures in gas turbines (Allianz, 1 978) and with its severe
effect on plant availability, there is a pressing need for a unified
treatment of the causes, ...
Gas Turbine Power Augmentation By Fogging Of Inlet Air.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Gas turbine output is a strong function of the ambient air temperature with power output dropping by 0.3 percent to 0.5 percent for every 1 F rise in ambient temperature. While this characteristic is inherent in any gas ...
Practical Methods For Field Performance Testing Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Detailed performance analysis of centrifugal compressors in the field essential to evaluate their existing condition. The current performance of a compressor can also be a valuable tool in evaluating its reliability. A ...
High Temperature Coatings For Industrial Gas Turbine Users.
(Texas A&M University. Turbomachinery Laboratories, 1999)
High temperature coatings are used for protecting the high temperature turbine components from environmental attack due to
oxidation and hot corrosion. These coatings have developed from simple aluminide coatings to complex ...
Steam Turbine Governing Systems And Electronic Governor Retrofit.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Steam turbine retrofitted governing systems are being designed with today’s technology to operate a turbine in a safe and reliable manner. The design is completed with an extreme amount of effort being concentrated in the ...
Rotordynamic Stability Tests On High-Pressure Radial Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1999)
This paper describes extensive measurements on high-pressure radial compressors with rated discharge pressures of more than 400
bar (5800 psi). The purpose of the measurements was to deterine m the damping behavior of the ...
Rerate Of Centrifugal Process Compressors - Wider Impellers Or Higher Speed Or Suction Side Boosting?.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Impeller exchange, speed increase, and supercharging are the
usual means to increase the capacity of existing industrial turbocompressors
of the single shaft type. Replacing an existing rotor by
a new one with wider ...
Applying Variable Speed Drives With Static Frequency Converters To Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Today, the variable speed drive with AC motor and static frequency converter is an outstanding solution to control the speed of turbomachines in the power range up to 100 MW and more. A wide selection of variable speed ...
