Delavan Oil nozzle 00275-45W7

The Delavan oil nozzle 00275-45W7 is a component for burners, responsible for spraying and mixing fuel with air to ensure optimal combustion. It has a capacity of 2.75 gallons per hour and a spray angle of 45 degrees. This W-type nozzle is neither truly hollow nor solid, and can be used in place of either solid or hollow cone nozzles within a flow range of 0.40 to 8.00 gph. The lower flow rates tend to be more hollow. Its article number is 345.892.066.

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

Common failure modes for oil nozzles include clogging, which can cause uneven spray patterns, reduced combustion efficiency, or difficulty igniting. A worn or damaged nozzle may lead to soot buildup, increased fuel consumption, or burner shutdown. Regular inspection and cleaning or replacement are recommended to maintain proper operation.
