🔍 Key Concepts

• Cleaning methods for steam-heated equipment in marine boilers and evaporators • Difference between mechanical descaling (impact tools, abrasion) and chemical/solution cleaning • Why tube materials (copper, copper-nickel, steel) can be damaged by hard impact tools

💭 Think About

• Ask yourself: Would high‑pressure steam coils inside an evaporator tolerate heavy impact or metal‑to‑metal hammering without risk of cracking or deformation? • Which method is more appropriate for internal scale removal from tubing that you cannot easily access from the outside? • Think about standard marine practice: how are heat exchanger tubes and evaporator coils usually cleaned to avoid damaging them?

✅ Before You Answer

• Eliminate any option that would dent, crack, or work‑harden thin‑wall tubes. • Consider which choice actually addresses scale removal rather than just surface dirt or grease. • Ask whether the method is gentle enough for pressure‑retaining coils yet effective on mineral scale.
