Q

Which of the listed mediums should be used when water washing a boiler?

🔍 Key Concepts

• Effects of salt vs fresh water on boiler internals and corrosion • Purpose of water washing a boiler (what are you trying to remove?) • Why temperature of the washing medium might matter for cleaning efficiency and metal stress

💭 Think About

• Think about how salt in the water would affect long-term condition of boiler tubes, drums, and internal surfaces. • Consider whether metal that has been in service at high temperature should be washed with water that is very cold, warm, or hot. • Ask yourself which option would best dissolve and carry away oil, soot, and soluble deposits without introducing new contaminants.

✅ Before You Answer

• Eliminate any choice that would introduce corrosive salts into the boiler internals. • Be cautious about thermal shock: big temperature differences between metal and wash water can cause damage. • Choose the option that both protects metal surfaces and improves cleaning effectiveness.
