Fluidics W2-150-60 nozzle

Fluidics W2-150-60 nozzle, article 480.892.092. This is an oil nozzle, a precision consumable part that atomises fuel oil into a fine cone for complete combustion. Parts of this type are selected by three parameters that together define how the flame sits in the combustion head: flow rate at the reference pressure, spray angle (typically between 30° and 80°), and spray pattern (hollow, solid, or semi-solid). The thread size must also match the burner head. When replacing such a nozzle, all three parameters must be taken from the burner data plate; a nozzle with the correct flow rate but wrong pattern can cause sooting, pulsation, or unstable ignition. In an oil-fired burner, the nozzle is the final component in the fuel delivery path. It receives oil from the pump, usually through a solenoid valve and sometimes a preheater. The nozzle is mounted in the combustion head, where the spray cone mixes with the combustion air delivered by the fan. Because the nozzle directly affects flame shape and stability, it is a wear item that should be changed at regular service intervals. When sourcing a replacement, confirm that the rating, angle, and pattern match the burner specification.
