COURSE OBJECTIVE

  •  Upon completion of this course, participants will gain a basic understanding of the main components and subsystems of gas turbine systems, steam power plants, co-generation, and combined cycle plants.
  • Participants learn to critique the advantages, applications, performance, and economics of co-generation and combined cycle plants.
  • They will learn about various auxiliary systems including instrumentation, controls and monitoring systems, deaerators, and feed water heater systems and will learn some basics about transformers and generators.
  • Participants will discover the basics required in minimizing operating cost and optimizing efficiency, reliability, and component longevity for gas turbine and steam power plants.
  • They will learn about the monitoring and control of environmental emissions and gain some insight into predictive and preventive maintenance, reliability, and testing.
  • Finally, they will discover some of the latest technology applicable to the areas covered and identify methods for self-improvement

 

WHO SHOULD ATTEND

 Engineers, technologists, operations, maintenance, repair and overhaul, systems optimization and performance verification, specification, retrofit design, business and management of power systems and personnel, and support of power generation trains and their support systems
Personnel can be involved in both large scale commercial power production and small in-house production
While this course is of major benefit to newer people in the field, it is also valuable as a revision and technology update for more experienced personnel.
