Delavan 0.60GPH, 60B (1) nozzle

This article is an oil nozzle sold under the Delavan brand, identified by catalogue article 345.892.091 and manufacturer code P0060-60B1. It is listed in the oil nozzles category. An oil nozzle of this type atomises fuel oil into a fine spray cone so that it can be fully burned in the combustion head. It is a precision consumable part. The flow rate, spray angle and spray pattern together determine how the flame sits relative to the blast tube and burner head. Parts of this class are selected by three parameters: fuel flow in US gallons per hour (GPH) or kg/h at the reference pressure, spray angle (typically 30°–80°), and spray pattern (hollow cone, solid cone or semi-solid cone). Using a nozzle with the correct rating but a wrong pattern can cause sooting, pulsation or unstable ignition. Therefore all three figures must match the burner data plate. The thread standard is also a selection factor, but that information is not given for this specific article. When replacing an oil nozzle, always fit a new gasket or O‑ring if the system uses one, and ensure the nozzle is torqued to the manufacturer’s specification. The nozzle works together with the oil pump, solenoid valve and preheater (if fitted) to deliver fuel at the correct pressure and timing. Burners of this class rely on the nozzle to produce a consistent spray; any wear or blockage directly affects combustion quality.
