Monarch 1.50GPH, 60R nozzle

The Monarch 1.50GPH, 60R nozzle is an oil nozzle for pressure-jet oil burners. This article is referenced under catalogue number 732.892.033 and manufacturer code 1.50GPH,60R, 732.892.033. Parts of this type are precision consumable components that atomise fuel oil into a fine spray for complete combustion. In the fuel delivery path, the nozzle is mounted on the burner blast tube and receives pressurised oil from the pump via the solenoid valve and, where fitted, a preheater. Oil nozzles are selected by three parameters: rated flow (in US gallons per hour or kg/h at a reference pressure, typically 7 bar or 100 psi), spray angle (commonly 30° to 80°), and spray pattern (hollow cone, solid cone, or semi-solid cone). The thread size must also match the burner adapter. All three parameters together determine how the flame sits in the combustion head and interacts with the air flow. Using a nozzle with the correct flow but wrong pattern can cause sooting, pulsation, or unstable ignition. When replacing a nozzle of this type, always verify that the rating, angle, and pattern on the burner data plate match the new part. The specifications of this individual article are as given in the name and codes above; for exact application, refer to the burner manufacturer's documentation.
