Q

The rate of fouling on the oil side of fuel oil heaters is directly related to the __________.

🔍 Key Concepts

• Heat transfer in fuel oil heaters and how flow rate affects deposit buildup • Relationship between oil velocity and tendency of particles/impurities to settle on hot surfaces • Difference between variables that change temperature/pressure and those that change scouring action inside tubes or coils

💭 Think About

• Which factor will most strongly affect how long oil stays in contact with the hot surface and how quickly it can overheat and form deposits? • Does changing steam pressure or coil shape change the actual cleaning/scouring action on the oil side as much as changing how fast the oil moves? • Think about which variable directly controls whether solids and heavy components in the oil are swept along or allowed to settle on the heater surfaces.

✅ Before You Answer

• Identify which option most directly affects oil velocity and contact time with the heating surface • Distinguish between effects on the steam side vs. the oil side of the heater • Ask: which choice is commonly adjusted in operation to reduce fouling and overheating in fuel oil heaters?
