🔍 Key Concepts

• Boiler waterside deposits (difference between soft/loose vs hard/adherent deposits) • What chemical boiling-out is used for in marine boilers, especially on new or repaired units • How different deposits (corrosion products, oxides, oil/grease, sludge) are normally removed (chemical vs mechanical/blowdown)

💭 Think About

• Ask yourself: During a chemical boil-out, what kind of contamination are we mainly trying to remove from the water side surfaces of a boiler? • Which of these deposits tends to be soft/loosely adherent and can be lifted and carried away by chemicals and circulation, instead of needing mechanical cleaning? • Which type of deposit is usually too hard or strongly attached to be removed by a simple chemical boil-out and would require more aggressive cleaning methods?

✅ Before You Answer

• Identify which option represents a soft, easily dispersed deposit rather than a hard scale or oxide layer. • Think about what is commonly present after new boiler installation or major repairs that requires a chemical boil-out before putting the boiler in service. • Eliminate any options that are typically removed by mechanical cleaning, scraping, or abrasive methods, not by a standard chemical boil-out.
