🔍 Key Concepts

• Distillate production capacity and what it tells you about heater performance • Difference between routine maintenance and symptom-based maintenance • Relationship between tube fouling and changes in flow/heat transfer

💭 Think About

• Ask yourself: what specific symptom would indicate that the tubes are dirty or fouled, rather than just a change in operating conditions? • Consider whether mechanical cleaning is something you want to do frequently, or only when certain performance indicators show a problem. • Think about which choice focuses on the condition of the equipment (its performance) versus just following a calendar schedule or changing system settings.

✅ Before You Answer

• Identify which option ties mechanical cleaning directly to a measurable performance change in the distilling plant. • Eliminate any choice that would cause you to mechanically clean too often without clear need, increasing wear, time, and cost. • Verify which answer reflects good engineering practice: act when evidence shows the tubes are no longer transferring heat efficiently.

Question 1 of 27070

When should mechanical cleaning of feed water heater tubes be accomplished?

Any time when increased steam flow to the feed water heater shell is required to maintain distillate production capacity.

Only when chemical cleaning fails to restore distillate production capacity to normal.

During regularly scheduled maintenance.

Any time there is a drop-off on distillate production capacity.
