Monarch-0.85GPH- und 60R-Düse

This is an oil nozzle from Monarch, identified by catalogue article 732.892.030 and manufacturer code 0.85GPH,60R. It belongs to the category of oil nozzles – precision consumable parts that atomise fuel oil into a fine spray for complete combustion. Parts of this type are selected by flow rate (given here in US gallons per hour at a reference pressure), spray angle, and spray pattern (hollow, solid, or semi-solid). The code on this nozzle indicates a flow rate of 0.85 GPH and a 60-degree spray angle with an R pattern, which typically denotes a solid cone, though the exact pattern should be confirmed against the burner data plate. When replacing an oil nozzle, all three parameters – rating, angle, and pattern – must match the burner manufacturer’s specification. A nozzle with the correct flow but wrong pattern can cause sooting, pulsation, or unstable ignition, while an incorrect angle may misplace the flame in the combustion head. The nozzle screws into the oil pump assembly and works together with the pump solenoid and, if fitted, a preheater. No further performance data or compatibility information is available for this specific article beyond the stated code and catalogue number.
