Delavan 15.00GPH, 60A Düse

This is an oil nozzle from Delavan, catalogue article 345.892.288, manufacturer codes 01500-60A7 and 345.892.288. The designation indicates a rated flow of 15.00 GPH and includes a 60-degree spray angle with a pattern code. Parts of this type atomise fuel oil into a fine cone so that it burns completely in the combustion head. The nozzle is a precision consumable: the flow rate (in GPH at the reference pressure), the spray angle, and the spray pattern together determine flame shape and stability. For correct combustion, all three parameters must match the burner manufacturer’s specification. A nozzle with the correct flow rate but the wrong pattern can cause sooting, pulsation, or unstable ignition. When selecting a replacement, always confirm the flow rate, spray angle, and pattern against the burner data plate. The exact meaning of pattern code A on this nozzle should be verified with the manufacturer’s documentation. The nozzle thread is standard for its class, but check thread compatibility when fitting to an existing oil pump or burner head.
