Fluidics W2-225-60 nozzle
This oil nozzle is a precision consumable part that atomises fuel oil into a fine spray for complete combustion. Parts of this type are mounted in the burner gun assembly, typically downstream of the pump and solenoid valve, and they direct the fuel cone into the combustion head. The nozzle is selected by three parameters that together define how the flame sits in the blast tube: the flow rate (in USGPH or kg/h at a reference pressure), the spray angle (commonly 30 to 80 degrees), and the spray pattern (hollow, solid, or semi-solid). The thread size must also match the burner adapter. When replacing a nozzle of this class, all three parameters must be taken from the burner data plate. Fitting a nozzle with the correct flow rate but the wrong pattern or angle can cause sooting, pulsation, or unstable ignition. Because the nozzle is a wear item, it should be replaced at every annual service or whenever combustion readings drift. The W2 designation in the article name indicates a specific type within the Fluidics range, but the rating and angle are defined by the full code – here 225 likely refers to flow rate (2.25 USGPH) and 60 to the spray angle, though this is not stated in the input data. Always verify the burner manufacturer’s specification before ordering.
