Choosing and fitting

When selecting a replacement oil nozzle of this type, verify that the flow rate (in GPH or kg/h at reference pressure), spray angle, and spray pattern (hollow, solid, or semi-solid) match the burner's data plate. The thread size must also be compatible with the burner. Incorrect selection can lead to sooting, pulsation, or unstable ignition.

Signs of failure

Oil nozzles of this kind can fail due to clogging, wear, or damage, leading to poor atomization. Symptoms include soot formation, flame instability, pulsation, or incomplete combustion. Check the nozzle for blockages or erosion and replace if necessary.
