🔍 Key Concepts

• combustion quality in boilers and how it affects smoke color • difference between white smoke vs. black smoke from the stack • how fuel temperature, viscosity, and atomization influence burning efficiency

💭 Think About

• Think about what happens to fuel oil spray and burning if the fuel is not properly prepared before entering the burner. • Ask yourself: which condition would most likely cause unburned or partially burned fuel droplets to pass through and appear as a light or white-looking vapor? • Consider how air supply versus fuel preparation (temperature, viscosity, atomization pressure) changes the appearance and color of stack emissions.

✅ Before You Answer

• Review how fuel oil temperature affects viscosity and spray fineness at the burner nozzle. • Recall the visual indications of too much air versus poor atomization in a boiler flame and stack. • Before choosing, match each option with expected smoke color (e.g., black, gray, or white) based on typical marine boiler troubleshooting guides.
