Boiler & HRSG Water Chemistry and Corrosion Control

Posted in Courses


This is a practical in-depth training course for power plant chemists and chemical engineers wishing to expand their knowledge and skills and to become more effective in their day to day roles dealing with thermal power plant chemistry. As it is a two-day course the focus is on the steam/water cycle in the plant with exclusion of cooling water and other water circuits in plant.
At the completion of this course the attendees should have a significantly increased understanding of cycle chemistry in a thermal power plant and the interrelationships between plant operation, cycle chemistry and potential failure modes due to corrosion and/or deposition throughout the cycle. A basic background level of power plant operations and chemistry knowledge is suggested for participants.
