Abstract
The paper presents a case study concerning the influence of the boiler feed water characteristics (mainly pH and dissolved oxygen) on the corrosion processes that may occur in the steam generation plant. The role of ammonia as pH regulator is analyzed, evidencing the operating problems created by ammonia overdosing in the feed water. Several solutions for boiler’s operation improvement are presented.
