🔍 Key Concepts

• Panting in boilers – what it looks/sounds like and when it happens • Effect of air–fuel ratio on flame stability and furnace pressure • How burner condition (sprayer plates, atomization, fuel temperature) affects combustion and furnace pressure swings

💭 Think About

• Think about what operating condition would make the furnace pressure and flame surge in and out, almost like breathing. • Which of these choices would most likely cause the flame to become unstable, sometimes almost blowing out and then re‑establishing repeatedly? • Consider how too much vs. too little air changes the flame shape, color, and steadiness in an oil‑fired boiler.

✅ Before You Answer

• Identify which options primarily affect air quantity versus fuel quality/atomization. • Recall: panting is a symptom of unstable furnace pressure and flame, not just dirty equipment or slightly cold fuel. • Ask: which condition would most likely cause repeated partial flame failure and re‑ignition, leading to pressure fluctuations in the furnace?
