🔍 Key Concepts

• Boiler water chemistry and how it affects steam quality • Difference between foaming/priming (carryover) and corrosion problems • Role of dissolved solids vs. dissolved gases in boiler operation

💭 Think About

• Which condition would make the boiler water behave more like soap or suds and create stable bubbles on the water surface? • Which options relate more to metal corrosion inside the boiler rather than to steam contamination? • Think about what would actually get carried with the steam into the drum and lines: solid particles, gas, or chemical imbalance?

✅ Before You Answer

• Identify which choice is directly associated with priming, foaming, and carryover in steam boilers • Eliminate options that are primarily linked to corrosion control rather than steam contamination • Confirm which factor would most likely increase surface tension effects and bubble formation in the boiler water
