🔍 Key Concepts

• Boiler tube "water-side" vs "gas-side" cleaning methods • Properties of hard scale deposits and how they are usually removed • Risks of mechanical damage to boiler tubes during cleaning

💭 Think About

• Which methods listed can actually reach and treat the inside water surfaces of many small tubes safely and uniformly? • For hard mineral scale, which process changes or dissolves the scale itself, rather than just scraping what you can reach? • Which option would be commonly used on shipboard as a planned maintenance method for a whole bank of tubes, not just spot-cleaning a few areas?

✅ Before You Answer

• Confirm which options are mainly for external / gas-side cleaning versus internal water-side surfaces • Consider which method minimizes tube wall damage and uneven cleaning while effectively attacking hard scale • Ask yourself which method is normally done under controlled conditions using a chemical specifically selected for scale removal
