Description

The Delavan 00800-45W7 is an oil nozzle with a capacity of 8 gallons per hour (GPH) and a spray angle of 45 degrees. It features a W spray pattern and is designed for use with fuel oil. The nozzle has a thread size of 1/8 inch BSPT and is compatible with preheaters if fitted. It operates under high fuel pressure to atomize fuel into a fine spray, ensuring complete combustion in the burner head and an optimal fuel-air mixture for efficient combustion.

Further details

Atomization principle	liquid dispersion into smallest droplets under high pressure
Installation position	at the end of oil supply line, downstream of oil pump and solenoid valve
Nozzle Type	W
Nozzle parameters	flow rate, spray angle, spray pattern must match burner data plate
Replacement importance	wearing part, replace at intervals specified by burner manufacturer
Replacement verification	confirm same flow rating, spray angle, spray pattern, and thread size
Solenoid valve control	controls start and stop of flow

Choosing and fitting

When selecting a replacement oil nozzle, verify that the flow rate (in GPH), spray angle, and spray pattern (hollow, solid, or semi-solid) match the burner data plate. The thread size must also match the burner head; most domestic oil nozzles use a standard 1/8 inch BSPT thread, but always confirm against the equipment. Incorrect nozzle specifications can lead to poor combustion, so all parameters must be checked before installation.

Signs of failure

Oil nozzles of this type can fail due to wear or blockage, leading to sooting, flame pulsation, or unstable ignition. These symptoms indicate that the nozzle may need replacement. Regular inspection and replacement at intervals specified by the burner manufacturer, typically during annual servicing, are recommended to maintain proper operation.
