Why take this course?
In this course, our specialist instructor Dimitris Antoniadis explains gas turbine operation, maintenance and troubleshooting from the inlet duct through to the compressor, combustor, power turbine, auxiliaries and control systems. Engineers will learn how key design and operating features influence reliability, and how to identify common failure modes using inspection findings, operating data and vibration analysis.
What you'll learn
After completing this course, you...
• will be familiar with the main gas turbine components, including the inlet duct, compressor, combustion chamber, power turbine, sealing systems, diaphragms and shroud blocks
• understand how compressor thermodynamics, rotor assembly, inlet guide vane control and surge protection influence stable gas turbine operation
• are able to interpret combustion chamber operating points, flame monitoring signals and the relationship between emissions and combustion conditions
• can describe the function of key auxiliary systems, including fuel gas, fuel oil, lubrication oil, hydraulic oil, purge air and fire detection systems
• understand gas turbine control functions, including start-up control, speed and load control, inlet guide vane control, fuel control and protection logic
• are better able to troubleshoot common gas turbine failure modes using operating trends, inspection results and vibration analysis

About the course
Gas turbines used in power plants require engineers to understand both the mechanical design of the machine and the operating logic that protects it. This course, led by Dimitris Antoniadis, follows the gas turbine gas path from the inlet duct and filter system through the compressor, combustion chamber and power turbine.
The course explains the technical role of major components and design features, including bleed heat, compressor rotor assemblies, inlet guide vane control, surge control, flame monitoring, emissions behaviour, turbine blade and nozzle thermodynamics, sealing diaphragms and shroud blocks.
Auxiliary and control systems are also covered in detail. Students will review fuel gas and fuel oil systems, lubrication and hydraulic oil systems, purge air, fire detection, gas turbine controllers, start-up sequences, speed/load control, fuel control and protection functions for vibration, overtemperature and compressor surge.
The maintenance section focuses on inspection requirements, inspection frequency, repair cases and practical troubleshooting. Examples include turbine blade damage, blade pinning, fault identification during operation and the use of vibration analysis to diagnose common gas turbine failure modes.
