Delavan Oil nozzle 38745-002

The Delavan Oil nozzle 38745-002 is a precision consumable component used in burners to atomize fuel oil into a fine spray for complete combustion. It is designed for use with various liquid fuels, including heavy and recycled oils, and features a siphon and air-lift design that produces a dense spray cone. This nozzle is resistant to clogging and is suitable for industrial and universal burners. It is identified by the SKU 38745-002 and is categorized under oil nozzles.

Parts of this type are selected by three parameters: flow rate (expressed in US gallons per hour or kg/h at a stated reference pressure), spray angle (typically 30° to 80°), and spray pattern (hollow cone, solid cone, or semi-solid). The thread size must also match the burner's nozzle holder. Before ordering, confirm these parameters from the burner data plate to ensure proper fit and function.

When items of this kind fail, common issues include sooting, pulsation, unstable ignition, or flame impingement, often due to incorrect flow rate, pattern, or angle. Clogging can also occur, leading to reduced atomization and incomplete combustion. Regular inspection and replacement during burner servicing are recommended to prevent these problems.
