Q

Which of the conditions listed can cause the flame of a mechanically atomized burner to be blown away from the burner tip when you are attempting to light off?

🔍 Key Concepts

• Mechanically atomized burners and how air and fuel interact at the burner tip • The effect of air flow patterns (primary/secondary air) on flame shape and stability • How hardware defects (diffuser, cone) differ from operating conditions (viscosity, excess air)

💭 Think About

• Which option would create an air stream that physically pushes the flame away from the burner tip during light‑off? • Which conditions mainly change how well the fuel burns (quality of combustion) rather than physically blowing the flame off the tip? • During ignition, is the flame more sensitive to air quantity/velocity or to long‑term hardware wear?

✅ Before You Answer

• Identify which choice directly affects air velocity and direction at the burner tip, not just mixture quality. • Separate combustion efficiency problems from flame stability problems. • Ask: for each option, would this more likely cause flashback, no ignition, poor burning, or specifically a blow‑off of the flame from the tip?
