🔍 Key Concepts

• Heat transfer in evaporators – how scale on heating surfaces affects efficiency and required steam/coil pressure • Contaminated (salinity) evaporator operation – relationship between heating surface condition and distilling capacity • Difference between problems caused by water level/production rate/pressure versus fouled heating surfaces

💭 Think About

• If you must keep raising the heating coil pressure just to maintain the same output, what does that suggest about how efficiently heat is getting from the steam side to the water side? • Which of the listed problems would make the evaporator LESS able to transfer heat at a given coil pressure, forcing you to increase that pressure? • Which options describe an effect (a result of high capacity) rather than the underlying cause that would demand higher coil pressure?

✅ Before You Answer

• Compare how high water level would affect coil exposure and heat transfer – would that require constant pressure increases or just change level settings? • Think about whether too much distillate production is a symptom or a cause of needing more coil pressure. • For each option, ask: does this condition make the heating surface effectively smaller or less efficient, forcing an increase in coil pressure to keep capacity up?
