🔍 Key Concepts

• Priming in boilers (what it is and how it affects steam quality) • Which components see the highest steam velocity and are most sensitive to moisture carryover • How wet steam can impact downstream equipment in the steam path

💭 Think About

• When priming occurs, where does the water carry over with the steam and which part of the system is exposed to that first? • Which option represents equipment that relies on dry, clean steam to avoid overheating, erosion, or thermal stress? • Among the choices, which component is directly in the main steam flow path leaving the boiler?

✅ Before You Answer

• Identify which listed components are located downstream of the steam drum in the main steam line • Consider which part is most susceptible to thermal shock, tube overheating, or erosion from water droplets • Eliminate any components that normally handle water flow control rather than high‑energy steam flow
