Fluidics W2-250-45 nozzle

The Fluidics W2-250-45 nozzle is an oil nozzle, a precision consumable part that atomises fuel oil into a fine spray cone so that it burns completely in the combustion head. Parts of this type are selected by their flow rate (given in GPH or kg/h at a reference pressure), spray angle (typically between 30 and 80 degrees), spray pattern (hollow, solid, or semi-solid), and thread type. All four parameters must match the burner manufacturer’s data plate. Using a nozzle with the correct flow but wrong pattern leads to sooting, pulsation, or unstable ignition. In the fuel train, such a nozzle sits downstream of the oil pump and solenoid valve; on some systems a preheater may be present. When replacing an oil nozzle, always verify the rating, angle, and pattern against the original specification — the model designation alone is not sufficient to guarantee correct operation.
