🔍 Key Concepts

• Boiler water hardness and the role of calcium and magnesium in feed water • Difference between scale (hard, adherent deposits) and sludge (soft, mud-like deposits) inside a boiler • How internal deposits affect heat transfer and tube metal temperature

💭 Think About

• Think about what solid compounds calcium and magnesium form when water is heated in a boiler and where those solids tend to attach. • Ask yourself which choice describes a hard, insulating deposit on tube surfaces versus a soft, removable deposit. • Consider what kind of tube problem develops gradually as minerals in hard water precipitate out and stick to hot metal surfaces.

✅ Before You Answer

• Verify which term refers to hard mineral deposits on the heating surfaces of the boiler tubes. • Distinguish between chemical corrosion (like pitting) and mechanical wear (like erosion). • Confirm which condition is most directly linked to untreated hard water entering the boiler.
