Choosing and fitting

Oil nozzles of this type are selected based on three key specifications: flow rate (GPH), spray angle, and spray pattern. Before ordering, verify the existing nozzle's markings or measure the flow rate and angle to ensure the replacement matches the burner's requirements. The nozzle must be compatible with the burner's fuel pump pressure and the combustion chamber design. Installation involves removing the old nozzle, cleaning the mounting surface, and torquing the new nozzle to the manufacturer's specified value.

Signs of failure

When oil nozzles of this kind fail or become clogged, the burner may exhibit incomplete combustion, soot formation, or a pulsating flame. The equipment might struggle to ignite or produce a noisy, unstable flame. Regular inspection and cleaning of the nozzle can prevent these issues, but if the nozzle is worn or damaged, replacement is necessary.
