Delavan Oil burner nozzle P0125-80W1

The Delavan P0125-80W1 is an oil burner nozzle with a capacity of 1.25 gallons per hour and a spray angle of 80 degrees. It features a W-type spray pattern, which is described as 'all purpose' and is neither truly hollow nor solid. This nozzle is designed to play an important role in burning fuel for heating systems, performing functions such as fuel dose adjustment, fuel spraying, flame formation, fuel economy, and emission reduction. It is compatible with flow rates ranging from 0.40 to 8.00 gph.

When selecting a replacement oil nozzle of this type, ensure that the capacity (in gallons per hour), spray angle, and spray pattern match the burner's requirements. The nozzle must be compatible with the burner's air pattern and flow rate range. Installation involves removing the old nozzle and fitting the new one securely, ensuring proper alignment and tightness to avoid leaks.

Common failure modes for oil nozzles include clogging due to debris or carbon buildup, which can cause uneven flame, poor combustion, or burner shutdown. A worn or damaged nozzle may result in improper fuel atomization, leading to soot formation, increased emissions, or reduced heating efficiency. Regular inspection and cleaning or replacement of the nozzle are recommended to maintain optimal burner performance.
