Advanced Technologies Used in the Design, Operation, and Maintenance of Gas Turbines and Centrifugal Compressors


  • Improved job performance and decision making capabilities where plant operations are involved.
  • Integrated understanding of practical plant machinery, design, operation, and maintenance requirements.
  • Unbiased technology transfer between participants who in many cases are machinery manufacturers, and plant operators.

Scope and subjects of the course

The course encompasses the advanced technologies used in the design, operation, and maintenance characteristics of centrifugal compressors and gas turbines:

The centrifugal compressor part of the course deals with the design and operation of centrifugal compressors used in refineries, pipelines, and down-hole pressurization. It deals with surge characteristics and controls of centrifugal compressors

The gas turbine part of the course discusses gas turbines as direct drives for compressors and pumps and with generators in cogeneration and combined cycle applications. The use of higher temperatures in design, leading to higher efficiencies. This also includes new cooling techniques as well as improved materials and coatings used in turbine blades.

Throughout the course 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.


This course is divided into two parts. The first part deals with design and general operation characteristics of gas and steam turbines in a combined cycle power plant and the second part of the course is devoted to the Heat Recovery Steam Generators (HRSG) and the performance augmentation of a combined cycle power plant and the characteristics of the plant. The course will be taught in its entity by Professor Meherwan P. Boyce Ph.D., P.E., CEng., using his text books:

Overview of Turbomachines and Turbomachinery Specifications

An overview and survey of turbomachines covering both mechanical and performance aspects are made as a foundation for the rest of the course. Major characteristics are accounted for in the selection of turbomachines, such as the layout, environment and arrangement, including general mechanical and aerothermal characteristics of turbomachines. Various ASME and API Codes covering compressors, gas turbines, gears, lubrication and instrumentation will be discussed. An emphasis is placed on specifying and designing for maximum reliability.

Centrifugal Compressor Design Characteristics

This section describes the compressor design characteristics and general purchasing procedures and types of compressor information to be considered, especially those described in API 617, in the selection of re-injection and pipeline compressors.

Centrifugal Compressor Performance Analysis

This section discusses the performance characteristics of compressors. It also deals with the changes in performance of a compressor with changes in inlet pressure, temperature and Mol. Wt., and their effect on the compressors surge characteristics. Modifications in design are discussed for changes in performance characteristics.

Centrifugal Compressors - Surge and Surge Detection

This section deals with an in-depth analysis of centrifugal compressor design and analysis. Discussion of the impeller design as it affects pre-rotation at the inlet as well as slip conditions at the exit are discussed in detail. Design parameters as applicable to surge and choke margins are fully analyzed. Losses in the impeller and diffuser are described. Description of surge and methods of detecting and controlling this phenomenon are discussed here. Both static and dynamic surge detection devices are studied. Control aspects and practical considerations are discussed.

Gas Turbine Technology

In this section, various types and sizes of gas turbines used in the petrochemical industry are discussed, with their classifications by size and application. Comparison is made between industrial and aircraft derivative type of gas turbines. Methods of increasing cycle efficiency and the output power are also discussed. An overview of fuels and materials considerations will be made. State of the art developments in gas turbine technology will also be reviewed. High temperature turbines in cogeneration and combined cycle applications and other developments are covered.

Axial Flow Compressors and Turbines

Key aerothermodynamics 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.

Combustors, Materials Coatings and Fuels

A description of types of combustors, chamber design, fuel atomization, ignition and combustor arrangements are presented. Metallurgical aspects of gas turbine blading, turbine wheel alloys, future materials and gas turbine coatings are discussed. The stress-time behavior of materials is also covered. Common failure modes and cases are presented. Sulphidation properties, specifications, fuel treatments and heavy fuel operation are also discussed. Coatings as applied to both the hot section components and the compressor will be discussed from both a life and performance point of view.


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.

Performance and Power Augmentation of gas Turbines

This section deals with the enhancement of gas turbine power and efficiency. We also discuss the effect on the performance of gas turbines under various operational conditions and problems encountered by the turbine such as blade tip rubs, refrigerated and water cooled inlets, skewed combustor profiles etc.
