Monarch 1.00GPH, ugello 80R

This Monarch oil nozzle is a precision consumable part that atomises fuel oil into a fine spray for complete combustion. It is mounted in the burner’s combustion head and connects to the oil pump via the fuel line. The nozzle’s flow rate, spray angle, and spray pattern together determine how the flame sits and burns within the blast tube. For a replacement to work correctly, all three parameters must match the burner manufacturer’s data plate – using a nozzle with the correct rating but the wrong pattern can cause sooting, pulsation, or unstable ignition. The catalogue article 732.892.080 is a Monarch 1.00GPH, 80R nozzle. While the flow rate (1.00 GPH at reference pressure) and spray angle (80°) are indicated by the designation, the spray pattern (hollow, solid, or semi-solid) must be verified against the burner specification. Such nozzles are selected by the burner’s fuel output requirement and the combustion head geometry. When replacing a nozzle of this type, always check that the new unit has the same flow rate, angle, and pattern as the original, and handle it carefully to avoid damaging the precision orifice.
