Boiler & HRSG Water Chemistry and Corrosion Control

Posted in Courses


This course provides attendees with a comprehensive and detailed review of the various forms of waterside degradation and corrosion that may occur in the HRSG and boiler water and steam circuits.   Subsequently, the various water treatment programs and their utility in controlling waterside damage are presented.  Numerous field case studies from recent Tetra projects are then used to give a real-world perspective. 

The course is primarily intended for plant chemists, operators and plant engineering staff yet technical personnel that are involved in new plant design or key O&M decision processes will also find the presented information of value.
