Question 1 of 27070

Fuel oil accumulation in a boiler double front is generally caused by __________.

🔍 Key Concepts

• Boiler burner operation and how fuel is introduced into the furnace • Difference between leaks under pressure vs. fuel that seeps when equipment is secured • How atomization and spray pattern affect where unburned fuel ends up

💭 Think About

• Which component is physically located where the double front can receive fuel from it most directly? • Which condition is most likely to allow a slow, continuous seep of fuel over time rather than a sudden large leak? • Think about what happens to fuel when the burner is shut down but one part of the fuel system doesn’t fully close off.

✅ Before You Answer

• Identify which choice involves a part that is supposed to shut off fuel flow completely when not firing • Consider which fault would result in small, repeated drips instead of a major pressurized leak • Ask whether the problem described would be localized at the burner front or more out in the fuel supply system
