Flame retention oil burners produce a flame that is how many degrees Fahrenheit hotter than conventional burners?

• A. 100-200 F hotter
• B. 0-100 F hotter
• C. 300-500 F hotter
• D. 500-700 F hotter

Answer: (C)

Flame retention burners are designed to hold the flame in the burner head longer and mix fuel and air more thoroughly. That longer residence time and enhanced mixing lead to more complete combustion, which raises the flame temperature compared to conventional burners. Because of this improved combustion, the flame is typically about 300 to 500 degrees Fahrenheit hotter than a standard burner. This higher flame temperature improves heat transfer and efficiency, though it requires proper burner tuning to avoid overheating the boiler or creating other combustion issues.
