Delavan Oil nozzle 00650-60W7

The Delavan Oil nozzle 00650-60W7 is a precision consumable component used in oil burners to atomize fuel oil into a fine spray for combustion. It has a flow rate of 6.5 GPH, a spray angle of 60 degrees, and a spray pattern designated as W. This nozzle is designed for use with fuel oil and is identified by the manufacturer code 00650-60W7. It is the final component in the oil train, receiving pressurized oil from the pump to ensure complete combustion.

When selecting a replacement oil nozzle, three parameters must match the burner setup: flow rate at the reference pressure, spray angle, and spray pattern (hollow, solid, or semi-solid cone). The thread must also match the nozzle holder. Verify these parameters against the burner data plate before ordering, as incorrect specifications can lead to sooting, pulsation, or unstable ignition.

Oil nozzles can fail due to clogging, wear, or damage, leading to poor atomization. Symptoms include sooting, pulsation, unstable ignition, or incomplete combustion. Check the nozzle for blockages or deformation and replace if necessary.
