Description

This Delavan oil burner nozzle has a flow rate of 0.85 GPH and a spray angle of 70°. It is a precision component that atomises fuel oil into a fine spray for complete combustion. The nozzle is installed in the combustion head and receives pressurised fuel from the pump. It provides optimal fuel atomization, efficient combustion, and reduces emissions of harmful substances. The connection thread is standard and the sealing washer must be renewed on installation.

Further details

Maintenance Requirement	Replace as part of routine burner service
Operating Principle	Atomises fuel oil into a fine spray
Replacement interval	consumable item, part of routine burner service
Spray pattern type	hollow cone, solid cone, semi-solid cone

Choosing and fitting

Nozzles of this type are selected by three parameters: flow rate (in US gallons per hour at standard reference pressure), spray angle, and spray pattern (hollow cone, solid cone, or semi-solid cone). Before ordering, verify that all three match the burner data plate. The flow rate controls fuel input and burner output; angle and pattern govern flame shape and stability. The connection thread is standard for this class, and the sealing washer should be renewed on installation.

Signs of failure

A failed or worn nozzle typically causes incomplete combustion, resulting in sooting inside the combustion chamber and on the flue passages. The burner may produce an unstable flame, exhibit pulsation or rumbling, fail to ignite reliably, or deliver insufficient heat output. Soot accumulation, reduced efficiency, or difficulty in maintaining combustion are signs that nozzle replacement should be considered.
