Brief

Why Boiler Feed Water Must Be Free of Oxygen & CO₂ (saVRee tutorial) explains what dissolved O₂ and CO₂ are, why they enter feed water, and how O₂-driven oxidative/pitting corrosion and CO₂-induced carbonic acid lower pH and damage steel. The short instructional video stresses gas removal and pH control to protect boilers, piping, valves, and overall water quality.

Why it matters

saVRee (video published 2026-07-31) explains that dissolved oxygen in boiler feed water causes oxidative corrosion and pitting on steel surfaces, while dissolved CO₂ forms carbonic acid that lowers pH and accelerates acid-type corrosion.

Key details

  • Keeping feedwater chemistry correct — removing dissolved O₂ and CO₂ and maintaining proper pH — preserves water quality and protects boilers, pipes, and valves, a practical operational requirement emphasized for engineers, technicians, and students.
Source evidence

Oxygen and carbon dioxide may seem harmless, but they can cause serious problems inside a boiler. In this video, you'll learn what these dissolved gases are, why they are found in boiler feed water, and how they can lead to corrosion and lower water quality. We also explain why keeping the correct pH level is important and why removing these gases helps protect boilers, pipes, and valves. Whether you're an engineering student, technician, or industry professional, this simple guide will help you understand an important part of boiler water treatment.
