Dissolved oxygen can be removed from the boiler water by __________.

Question 1 of 27070

Dissolved oxygen can be removed from the boiler water by __________.

🔍 Key Concepts

• boiler water treatment methods for removing dissolved gases • difference between mechanical removal (vents, blows, deaeration) and chemical removal • role of oxygen in causing corrosion in boilers

💭 Think About

• Which choice describes a method that reacts directly with oxygen in the water rather than just replacing or filtering the water? • Do frequent blows or dumping/refilling actually eliminate dissolved oxygen already in the feedwater system, or just temporarily change the water in the boiler? • Can normal filters remove a gas dissolved in water, or are they mainly for solids?

✅ Before You Answer

• Identify which option would specifically target dissolved oxygen, not just sludge or scale. • Ask: which practice is used routinely in standard boiler water treatment programs aboard ships? • Eliminate any option that mainly deals with solids removal or general housekeeping rather than gas removal.
