Choosing and fitting

When selecting a replacement oil burner nozzle, it is essential to match the capacity (in gallons per hour or kg/h), spray angle, and spray pattern (solid-cone, hollow-cone, or semi-solid) to the burner's requirements. The nozzle must be compatible with the fuel type and the burner's design. Installation involves removing the old nozzle, cleaning the mounting threads, and tightening the new nozzle to the specified torque without over-tightening. Always verify the nozzle's specifications against the burner's manual before installation.

Signs of failure

Common failure modes for oil burner nozzles include clogging due to dirt or debris, which can cause incomplete combustion, soot buildup, or a noisy flame. A worn or damaged nozzle may result in an uneven spray pattern, leading to poor ignition or flame instability. If the burner fails to start or produces a smoky flame, inspect the nozzle for blockages or wear and replace it if necessary.
