Choosing and fitting

When selecting a replacement oil burner nozzle of this type, ensure the capacity (in GPH or kg/h), spray angle, and spray pattern match the original specifications. The nozzle must be compatible with the burner's flow rate and combustion chamber design. Installation involves removing the old nozzle, cleaning the mounting threads, and tightening the new nozzle to the recommended torque without over-tightening. Always verify the nozzle's dimensions and thread type before ordering.

Signs of failure

Common failure modes for oil burner nozzles include clogging due to dirt or debris, which can cause uneven spray, poor combustion, or soot buildup. A worn or damaged nozzle may lead to incomplete fuel atomization, resulting in increased fuel consumption, smoke, or a noisy flame. If the burner fails to ignite or produces a weak flame, inspect the nozzle for blockages or wear and replace it if necessary.
