🔍 Key Concepts

• High-temperature corrosion in boilers and how it differs from simple soot fouling • The role of ash, vanadium, and sodium salts in forming low-melting-point deposits on boiler tubes • How fuel impurities can change the deposit melting point and attack tube metal at elevated temperatures

💭 Think About

• Think about which contaminants in fuel oil can form molten deposits on hot tube surfaces rather than just dry, powdery soot • Consider which of the listed substances can combine with each other to make corrosive compounds at high temperatures • Ask yourself: in practice, are boiler tube corrosion problems usually linked to one single contaminant, or to the combined effects of several impurities?

✅ Before You Answer

• Check which substances are known to lower the melting point of ash deposits, causing sticky or molten slag on tubes • Verify which listed impurities are commonly controlled or limited in marine fuel specifications because of high-temperature corrosion risk • Before choosing, confirm whether each option can contribute to slagging and corrosion, not just normal fouling or dirt buildup
