·         Learn to critique the advantages, applications, performance, and economics of co-generation and combined cycle plants

·         Learn about various auxiliary systems including instrumentation, controls and monitoring systems, deaerators, and feedwater heater systems

·         Learn some basics about transformers and generators

·         Discover the basics required in minimizing operating cost and optimizing efficiency, reliability, and component longevity for gas turbine and steam power plants

·         Learn about the monitoring and control of environmental emissions

·         Gain some insight into predictive and preventive maintenance, reliability, and testing

·         Discover some of the latest technology in all of the above

·         Identify methods for self-improvement





Who Should attend?

 

This course is for all engineers, technologists, and other operational personnel who currently or may in the future be involved with the technology or business of running a power generation plant. This is regardless of whether the personnel are involved in:

·         Large scale commercial power production

·         Small power production as a tax incentive or production for in-house needs or

·         Merchant power production

It also is independent of whether the personnel are involved in 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.

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.
