Monarch 60.00GPH, 80PLP nozzle

This is an oil nozzle from Monarch. It atomises fuel oil into a fine cone so that combustion can be complete and stable. As a precision consumable part, the nozzle’s rating, spray angle and spray pattern together determine how the flame sits in the combustion head. The designation on this nozzle, 60.00GPH and 80PLP, indicates its flow rate (in US gallons per hour at the reference pressure) and its spray angle and pattern code. For a burner to operate without sooting, pulsation or ignition instability, all three parameters – flow rate, angle and pattern – must match the values specified on the burner data plate. When replacing a nozzle, verify the existing part’s marking and select a unit with the same GPH rating, angle and pattern designation. The nozzle threads into the oil line and works with the oil pump and solenoid valve; correct atomisation depends on the pump pressure being set to the reference value used for the nozzle rating.
