فوهة Monarch 12.00GPH، 60HO

Monarch 12.00GPH, 60HO nozzle, catalogue article 732.892.138. This is an oil nozzle, a precision consumable part that atomises fuel into a fine spray cone for complete combustion. Nozzles of this class are selected by three parameters: flow rate (in GPH or kg/h at the reference pressure), spray angle (typically 30–80 degrees), and spray pattern (hollow cone, solid cone, or semi-solid). The thread size must also match the burner’s nozzle holder. Using a nozzle with the correct rating but a wrong pattern or angle can cause sooting, pulsation, or unstable ignition, so all three must correspond to the burner data plate. This article is a Monarch branded nozzle. The name itself indicates the flow rate and a designation that, together with the article number, identifies the exact specification. When replacing a nozzle of this type, always verify the existing nozzle’s markings or consult the burner manual. The nozzle sits between the oil pump and the combustion head; it is the final component that shapes the fuel spray before ignition. Regular replacement (typically once per season) is standard practice because wear and carbon buildup alter the spray characteristics. No additional interpretation of the product code is provided here.
