Q

Evaporator priming can be caused by high water level, fluctuating steam pressure, or __________.

🔍 Key Concepts

• Evaporator priming: what it is and why it happens in distilling plants or boilers • How sudden changes in operating conditions can carry water droplets into the vapor stream • The difference between problems caused by level/foaming vs. those caused by temperature or concentration

💭 Think About

• Which choice would most directly cause unstable conditions inside the evaporator, similar to how fluctuating steam pressure does? • Which option would tend to make the liquid surface more likely to surge and entrain droplets into the vapor, instead of just changing efficiency or capacity? • Think about which factor would change rapidly and repeatedly during operation, not just be too high or too low once.

✅ Before You Answer

• Make sure you know the definition of priming (water carryover with the vapor) rather than simply reduced output or lower purity. • Ask: does this factor mainly affect stability of boiling and vapor formation, or does it mainly affect how salty/concentrated or how cold/hot the feed is? • Check which option would most logically work as a parallel cause with high water level and fluctuating steam pressure—all three should be of the same general nature (causing surging/instability).
