Delavan Oil nozzle 30609-007

The Delavan Oil nozzle 30609-007 is a precision component used in oil burners to atomize fuel oil into a fine spray for efficient combustion. It is categorized as an oil nozzle and is designed for use with fuel oil. This nozzle is a consumable part that should be replaced during annual service to maintain optimal burner performance. It is manufactured by Delavan and is identified by SKU 30609-007.

When selecting a replacement oil nozzle, three interdependent parameters must match the burner manufacturer's specification: flow rate (in USGPH or kg/h at a stated reference pressure, typically 100 psi or 7 bar), spray angle (commonly between 30 and 80 degrees), and spray pattern (hollow, solid, or semi-solid cone). The thread size is also critical for a proper seal; most domestic and light commercial oil nozzles use 1/8" NPT or BSP threads. Always verify the existing nozzle before ordering to ensure correct dimensions and specifications.

A worn or incorrectly selected oil nozzle can cause sooting, flame pulsation, unstable ignition, or poor combustion efficiency. Even a slightly worn nozzle degrades flame quality and increases soot deposits. Regular inspection and replacement at annual service are necessary to prevent these issues.
