Question 1 of 27070

Q

Foaming in boiler water is a result of __________.

🔍 Key Concepts

• Boiler water impurities and contamination (suspended vs dissolved solids, oil, etc.) • Difference between foaming, priming, and carryover • Purpose of surface (skimmer) blows in boiler operation

💭 Think About

• Ask yourself: Is foaming usually the CAUSE of carryover, or is carryover the cause of foaming? • Which condition in the options would make the water surface more likely to form stable bubbles and a frothy layer? • What is the normal purpose of surface blows—do they generally increase impurities at the surface, or reduce them?

✅ Before You Answer

• Identify which choice describes a condition inside the boiler water that would directly promote bubble formation and a frothy water surface. • Eliminate any choices that are actually results/symptoms of foaming rather than the root cause. • Consider which operation (like surface blows) is normally used to control total solids and foaming, not create it.
