🔍 Key Concepts

• Color of flame vs. combustion efficiency in boiler fireboxes • Relationship between fuel/air ratio and flame appearance • Effects of fuel temperature and pressure on atomization and burn quality

💭 Think About

• Think about what a clean, hot, nearly smokeless flame should look like in a properly adjusted boiler burner. • Consider how poor atomization (from wrong fuel temperature or pressure) would change the flame color and shape. • Ask yourself: does too much excess air usually make the flame whiter and more intense, or paler and more diffuse?

✅ Before You Answer

• Identify which option describes conditions that give good atomization and near-complete combustion. • Eliminate any options that would normally cause smoke, yellow/orange color, or a lazy flame. • Decide whether excess air generally improves or worsens combustion efficiency and how that shows in flame color.
