Description

The Delavan Oil nozzle P0165-45W1 is a precision consumable component used in oil burners to atomize fuel oil into a fine spray for efficient combustion. It has a capacity of 1.65 gallons per hour (GPH) and a spray angle of 45 degrees. The spray pattern is designated as 'W', which is an all-purpose type that can often replace either solid or hollow cone nozzles. This nozzle is compatible with flow rates ranging from 0.40 to 8.00 GPH, with lower flow rates exhibiting a more hollow spray behavior. The article number for this item is 345.892.062.

Choosing and fitting

When selecting a replacement oil nozzle of this type, ensure that the flow rate (GPH), spray angle, and spray pattern match the burner manufacturer's specifications as indicated on the data plate. The nozzle must be compatible with the burner's air pattern; 'W' type nozzles are versatile and can frequently be used in place of solid or hollow cone nozzles within the specified flow range. During installation, it is recommended to replace the gasket or o-ring on the nozzle adapter and verify that electrode gaps and positioning relative to the nozzle are correct according to the burner manual.

Signs of failure

If an oil nozzle of this kind is worn or incorrectly matched, common symptoms include sooting, pulsation, or unstable ignition. A mismatched spray angle may cause the flame to impinge on the combustion head or heat exchanger, leading to incomplete combustion and increased emissions. Regular inspection and replacement of the nozzle are necessary to maintain proper fuel-air ratio and combustion efficiency.
