HRSG Design and Operation

The course is primarily intended for O&M staff at all levels of experience working in combined cycle power plants, but should also be of interest to engineers and managers involved in new project development. The course gives attendees a comprehensive yet in-depth survey of a broad range of topics relating to the design, operation and maintenance of the HRSG and associated steam cycle systems.
Drawing on our field experience working at power plants throughout the world, the objective is to provide attendees with clear instruction on the operator actions and design issues that impact HRSG reliability, efficiency and operating life.

Public courses are regularly held at both our European (France) and USA training facilities. Courses can also be delivered on-site and tailored to a client’s specific needs if required. Please contact your local Tetra training coordinator for further details (see website for details).
