Description

The Monarch Oil nozzle 30.00GPH / 45HO is an oil nozzle with a flow rate of 30 GPH, a 45 ° spray angle, and an HO spray pattern. It is used to atomise fuel oil into a spray for combustion in oil-fired burners and boilers. The 45 ° angle defines the cone of the spray, while the HO pattern describes the distribution of fuel within that cone. The 30 GPH rating states the volume of oil the nozzle passes per hour at its rated pressure.

Choosing and fitting

Oil nozzles of this type are selected by matching the flow rate, spray angle, and spray pattern to the burner manufacturer's specification. The mounting form must also match: nozzles are commonly secured by a threaded body or a flange, and the seat and thread must correspond to the nozzle holder. Before ordering, compare the markings on the existing nozzle and the burner's data plate, and check the pump pressure the rating is based on.

Signs of failure

Oil nozzles of this kind can clog, wear at the orifice, or develop a distorted spray pattern over time. When this happens, the burner may show a weak or uneven flame, delayed ignition, sooting, or a rise in flue gas temperature. Check the nozzle for blockage or wear, verify the pump pressure, and replace the nozzle if the spray pattern or flow rate no longer matches specification.
