Delavan Oil nozzle 00650-60B7

The Delavan Oil nozzle 00650-60B7 is a precision consumable component used in pressure-jet oil burners to atomize fuel oil into a fine spray for efficient combustion. It has a capacity of 6.5 gallons per hour (GPH) and a spray angle of 60 degrees, with a spray pattern type B. This nozzle is referenced under article numbers 00650-60B7, 3042222, and 345.892.120. It is designed to be replaced during annual maintenance to ensure optimal burner performance.

When selecting a replacement oil nozzle of this type, the flow rate (in US GPH at 100 psi), spray angle, and spray pattern must match the burner manufacturer's specification on the data plate. The nozzle is mounted in the burner's blast tube, downstream of the oil pump and solenoid valve. The thread is standard for this class of component. Incorrect matching of these parameters can lead to sooting, pulsating combustion, or unstable ignition.

Failure of oil nozzles of this kind can manifest as sooting, pulsating combustion, or unstable ignition. These issues may occur if the nozzle is worn, clogged, or incorrectly matched to the burner. Regular inspection and replacement during annual maintenance are recommended to prevent such problems.
