What is the most likely impact of a clogged nozzle in an oil burner?

A clogged nozzle in an oil burner significantly disrupts the fuel delivery system, leading to an unstable flame and poor combustion. The nozzle is responsible for atomizing the oil into a fine mist, which mixes with air for efficient burning. When the nozzle becomes clogged, it restricts or alters the flow of fuel, causing incomplete combustion. This can lead to a flickering or uneven flame, reduced heat output, and the potential for soot buildup or other emissions problems.

The impact of poor combustion includes not only decreased efficiency but also an increase in harmful emissions, which can pose safety and environmental concerns. Furthermore, the erratic performance could lead to operational issues for the burner, necessitating repairs or replacements to restore proper function. Understanding these effects is crucial for maintaining an efficient and safe heating system.
