Question 1 of 27070

Accumulation of fuel oil in the boiler double casing could be caused by __________.

🔍 Key Concepts

• How fuel is supplied, atomized, and returned in a steam-atomizing boiler system • Where oil can leak or drip into the double casing area versus into the burner front • The function of return traps in a steam-atomized fuel system

💭 Think About

• Which component, if it is not working correctly, would actually allow oil to build up and stay inside the double casing, rather than just leak externally or be burned? • Think about which choice would cause continuous, low‑rate oil entry into the casing space, especially when the burner is at low fire or shut down. • Which option affects the removal or return of unburned oil from the burner assembly back to the fuel system?

✅ Before You Answer

• Identify which listed components normally handle oil that is not fully burned and send it back to a tank or drain. • Consider which fault would leave oil with nowhere to go, causing it to accumulate in an enclosed space like the double casing. • Eliminate options that mainly affect oil cleanliness or spray quality rather than its physical accumulation in the casing.
