What can be the effect of overfiring in an oil burner system?

Overfiring in an oil burner system leads to a risk of equipment damage due to the excessive heat generated in the combustion process. When an oil burner operates at a higher input than designed, it can cause various components, such as the heat exchanger, to overheat. This overheating can lead to warping, melting, or cracking of critical parts, resulting in expensive repairs or even complete system failure.

Additionally, overfiring can negatively impact the combustion process, leading to incomplete combustion, which may create soot buildup in the furnace and diminish the overall functionality of the burner. Proper tuning and adjustment of the burner are crucial to maintain safe and efficient operation, preventing the likelihood of damaging effects from overfiring.
