Question 1 of 27070

Which of the significant combustible elements of fuel oil is a major source of boiler corrosion?

🔍 Key Concepts

• Combustion products of fuel oil and how they affect metal surfaces in boilers • Difference between elements that mainly provide heat energy vs those that form corrosive acids • How impurities in fuel can affect boiler tubes, economizers, and uptake areas

💭 Think About

• When fuel oil burns, what chemical compounds are formed that can attack steel surfaces, especially at lower temperatures (like in the economizer)? • Which element in fuel, when combined with water (from combustion) and possibly oxygen, is most likely to form strong acids? • Think about which element is most associated with soot and heat, and which is most associated with acid formation and low‑temperature corrosion.

✅ Before You Answer

• Identify which element’s combustion products can form acids in the presence of moisture • Consider which elements are primarily energy carriers (burn to produce heat) and are less directly responsible for corrosion • Recall standard marine engineering teaching on low‑temperature corrosion in boiler uptakes and economizers and which fuel constituent causes it
