Boquilla «W1-200-45» de Fluidics

The Fluidics W1-200-45 nozzle is an oil nozzle, catalogue article 480.892.095. Parts of this type atomise fuel oil into a fine spray cone so that it burns completely in the combustion head. The nozzle is a precision consumable component: over time, wear or carbon build‑up alters the spray pattern and flow, which directly affects flame stability and combustion efficiency. In the oil burner system, the nozzle sits downstream of the pump and solenoid valve; the pressurised oil is delivered to the nozzle, where it is forced through the orifice to form a spray. When selecting a replacement oil nozzle, three parameters must match the burner manufacturer’s specification: the flow rate (typically given in US gallons per hour at a reference pressure, or in kg/h), the spray angle (commonly 30° to 80°), and the spray pattern (hollow, solid, or semi‑solid). The thread size must also be compatible with the burner’s nozzle holder. Using a nozzle with the correct flow and angle but the wrong pattern can cause sooting, pulsating combustion, or ignition failure. Conversely, a nozzle of the correct pattern but incorrect flow will alter the burner output and may lead to incomplete burn or overheating of the combustion head. For a reliable replacement, always verify the data on the burner’s rating plate or in the service manual. Nozzles from different manufacturers are not interchangeable by appearance alone; the stamped codes on the nozzle body should be cross‑checked. When fitting, handle the nozzle with clean gloves to avoid clogging the orifice with grease or lint, and tighten to the torque specified by the burner maker—overtightening can distort the spray angle.
