June, 2018: Effective Operation of HRSGs

June 12 & 13, 2018 in Sophia Antipolis, France

Course Overview:

This seminar 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.
Tetra Engineering has offered this seminar for many years and it is updated annually. Recent seminar sites have included USA, Turkey, UAE, the Philippines and Malaysia.
