Q

Which of the conditions listed could be responsible for the flame of a mechanical atomizer to blow out when attempting to light off?

🔍 Key Concepts

• Operation of a mechanical atomizer and how fuel/air mixing works at light-off • Effect of air flow paths (diffuser, air doors) on flame stability and possible blow-out • Influence of fuel properties such as viscosity on spray quality and ignition

💭 Think About

• Think about what physically causes a flame to blow out: is it usually too much air velocity, not enough air, or poor fuel atomization? • Which of the listed parts mainly control the way air moves around and across the burner tip during ignition? • How would very low viscosity affect atomization and spray pattern at the burner—would it tend to snuff out a flame, or just change droplet size?

✅ Before You Answer

• Identify which option most directly affects air flow and velocity over the burner tip at the moment of light-off. • Consider which adjustments (diffuser vs distance piece) primarily influence spray pattern versus air swirl/velocity. • Verify that the condition you choose could reasonably cause the air stream to physically blow the small initial flame off the burner during ignition.
