Buse Delavan 3.00GPH, 60W (7)

The Delavan 3.00GPH, 60W (7) nozzle is an oil nozzle for use in pressure-jet oil burners. It is a precision consumable that atomises fuel oil into a fine spray for complete combustion. The part is identified by manufacturer codes 00300-60W7, 3042152, and 345.892.008. The specific rating, spray angle, and pattern define how the flame sits in the combustion head; for this article, the flow rate is 3.00 US gallons per hour at the reference pressure, the spray angle is 60 degrees, and the pattern code is W. When selecting a replacement nozzle, three parameters must match the burner data plate: flow rate (in GPH or kg/h at the reference pressure), spray angle (typically 30–80 degrees), and spray pattern (hollow, solid, or semi-solid). Using a nozzle with the correct rating but the wrong pattern can cause sooting, pulsation, or unstable ignition. The thread type (commonly 3/8-24 or 1/8-27) must also match the nozzle adaptor. Always confirm the burner manufacturer’s specification before fitting. This nozzle is a direct replacement for applications requiring the stated GPH, angle, and pattern.
