Q

High boiler water level can cause carryover and __________.

🔍 Key Concepts

• Boiler carryover and how water level affects moisture in steam • Which boiler components are exposed first to wet or contaminated steam leaving the drum • The normal flow path of steam: drum → superheater → main steam line → other heat‑recovery components

💭 Think About

• Think about what happens if the steam leaving the drum contains water droplets: which downstream part of the system would see that steam immediately? • Consider which listed component is designed for dry, high‑temperature steam, and would be most vulnerable if that steam instead contained water and impurities. • Look at the order in which gases and steam pass by the economizer, waterwall tubes, screen tubes, and superheater tubes—where does the steam itself actually flow?

✅ Before You Answer

• Verify which of the choices are primarily on the gas side (heated by exhaust gases) versus on the steam side (directly carrying steam). • Confirm which component’s metal temperature is highest under normal operation, making it more sensitive to quenching or deposits from carryover. • Make sure you know the steam flow sequence in a marine water‑tube boiler before deciding.
