The course encompasses the design and general operation and maintenance characteristics of centrifugal compressors and gas turbines. The course teaches overall design and operation concepts incorporating basic operation and maintenance problems for gas turbines and centrifugal compressors.
The gas turbine part of the course discusses gas turbines as direct drives for compressors and pumps and cogeneration and combined cycle applications.
An emphasis is placed on providing practical information with minimal theory and is aimed at engineers and operational personnel who need a broad-based introduction to practical operation and design considerations of centrifugal compressors and gas turbines. Discussion throughout the course of plant problems with the instructor and amongst the course attendees is encouraged so as to maximize the course experience.
The course also the computation of the performance of gas turbines and centrifugal compressors is discussed. Course participants will be taken through the computations of gas turbine and centrifugal performance tests on software supplied and the proper correction factors applicable. Attendees should bring their lap top computers so that sample computations can be carried out in conjunction with the instructor.

Key aerothermodynamic considerations are covered including cycle analysis of gas turbines and centrifugal compressors. Gas turbine performance calculations will also be covered. This section also covers mechanical, performance and aerodynamic aspects of gas turbines. Radial inflow turbines are also discussed. Practical aspects as related to gas turbines are emphasized in the discussion.

Coatings as applied to both the hot section components and the compressor will be discussed from both a life and performance point of view.
Fuels
Discussion on various types of fuels will be conducted from natural gas to heavy fuel oil to low BTU gas. The behavior of the gas turbines on these different fuels will be studied as to their effect on gas turbine performance including the effect on gas turbine compressor surge and on the heat recovery unit as well as on duct burners if used in the system.
Instrumentation
An overview of instruments used for monitoring and diagnostics of TurboMachinery is presented. Instrumentation covered includes pressure, temperature, flow, vibration, torque, etc. Real-time analysis, balancing, instrumentation, signal tape recorders, and various types of analyzers will be discussed.
Maintenance
Case histories of various types of failures and maintenance problems of onshore and offshore gas turbine compressor installations are discussed. Maintenance techniques using borescope and spectrum analysis, including acoustic monitoring are discussed. Techniques for checking and conducting repairs on impellers, diffusers, bearings and foundation repairs are emphasized.
Detailed Performance Testing Computations for Centrifugal Compressor and Gas Turbines
Performance computations will be as per various ASME codes PTC 19.1, and 22. Techniques for computing performance of the advanced gas turbines in design and off design operation will be studied. Most new advanced gas turbines operate at very high turbine firing temperatures. Thus variation in this firing temperature significantly affects the performance and life of the components in the hot section of the turbine. The compressor pressure ratio is high which leads to a very narrow operation margin, thus making the turbine very susceptible to compressor fouling. The pressure drop through the air filter and dirty compressors also results in major deterioration of the performance of the turbine, thus emphasis will be placed on this computation.
Centrifugal Compressor computations will be carried out as per ASME PTC 10. The code deals with both field test as well as closed loop tests at the factory. The three classification of the test will be examined and the computations compared. Surge points and surge computations will be examined. It is suggested that attendees bring with them lap top computers so that sample computations can be carried out in conjunction with the instructor.
