Monarch-9.00GPH- und 45PLP-Düse

This is a Monarch oil nozzle with a rating of 9.00 GPH and a 45-degree spray angle, coded PLP. The part number is 732.892.109. Oil nozzles of this type are precision consumables that atomise fuel oil into a fine spray cone, enabling complete combustion in the burner head. The three defining parameters for any oil nozzle are the flow rate (in GPH or kg/h at a reference pressure), the spray angle, and the spray pattern – hollow, solid, or semi-solid. Together they determine how the flame sits relative to the combustion head. A nozzle with the correct flow rate but the wrong pattern or angle can cause sooting, pulsation, or unstable ignition, so all three values must match the burner data plate. When replacing an oil nozzle, confirm that the existing burner setup uses the same thread type (typically 1/8’’ BSP or NPT) and that the pressure at the pump corresponds to the rating. The PLP designation indicates a specific spray pattern; this should be matched exactly to the original specification. The 9.00 GPH rating is a relatively high flow, common in larger industrial burners. No additional compatibility with specific boiler models or further details are provided in the data.
