فوهة Monarch 4.00GPH، 60PLP

This oil nozzle is a precision consumable part that atomises fuel oil into a fine spray cone for complete combustion. The spray pattern, flow rating and spray angle together determine how the flame sits inside the combustion head. For any given burner, all three parameters must match the data plate, otherwise sooting, pulsation or unstable ignition can occur. This specific article is a Monarch nozzle with the designation 4.00GPH, 60PLP, catalogue article 732.892.003. The flow rating, spray angle and pattern are indicated by that designation, and the nozzle must be replaced with one that has the identical specification to maintain proper burner operation. Nozzles of this type are selected by their flow rate in GPH at the reference pressure, the spray angle in degrees, and the pattern type – hollow, solid or semi-solid – plus the thread size. When replacing, confirm the thread and ensure the nozzle is tightened to the correct torque; over- or under-tightening can distort the spray. Because the nozzle is a consumable, it should be changed at regular service intervals as part of burner maintenance.
