Nozzle Type

Choosing and fitting

When selecting a replacement oil nozzle of this type, ensure the capacity (in GPH), spray angle, and spray pattern match the burner's requirements. The nozzle's flow rate and angle must correspond to the burner's design for proper combustion. Installation typically involves removing the old nozzle and screwing in the new one, ensuring a secure fit without overtightening. Always compare the specifications of the existing nozzle before ordering to guarantee compatibility.

Signs of failure

Common failure modes for oil nozzles include clogging due to debris or carbon buildup, which can cause uneven flame, soot formation, or difficulty igniting. A worn or damaged nozzle may lead to poor atomization, resulting in incomplete combustion, increased fuel consumption, or burner shutdown. Regular inspection and cleaning or replacement of the nozzle can prevent these issues.
