Delavan Oil nozzle 00300-90B7

The Delavan oil nozzle 00300-90B7 is a precision component designed to atomize fuel oil into a fine spray for combustion in oil burners. It has a capacity of 3 gallons per hour, a spray angle of 90 degrees, and a spray pattern type B. This nozzle is suitable for use with fuel oil and is a consumable part that directly influences flame shape and ignition stability.

When selecting a replacement nozzle of this kind, match the flow rate (in USGPH or kg/h at the reference pressure), spray angle, and spray pattern (hollow, solid, or semi-solid) to the burner's specifications. The thread type must also correspond to the nozzle holder. Always verify these parameters against the burner data plate before fitting.

Failure of this kind of nozzle can lead to pulsation, delayed ignition, or excessive soot formation due to an incorrect spray pattern or wear. Check the nozzle for clogging, erosion, or damage if the flame is irregular or combustion is unstable.
