Delavan Oil burner nozzle 00250-60W7

The Delavan 00250-60W7 is an oil burner nozzle with a spray angle of 60 degrees and a W (all-purpose) spray pattern. It has a capacity of 2.5 gallons per hour and is designed for use in oil burners to atomize fuel for combustion. The nozzle includes a fuel supply adjustment mechanism to optimize performance under varying conditions. It is compatible with flow rates ranging from 0.40 to 8.00 gph.

When selecting a replacement oil nozzle, ensure the capacity (in gallons per hour), spray angle, and spray pattern match the burner's requirements. The nozzle type (e.g., solid, hollow, or W) should be chosen based on the burner's air pattern and desired flame shape. Installation involves removing the old nozzle and installing the new one with proper torque, ensuring no debris enters the fuel line.

Common failure modes for oil nozzles include clogging due to dirt or carbon buildup, which can cause poor atomization, uneven flame, or soot formation. A worn or damaged nozzle may lead to incomplete combustion, increased fuel consumption, or burner shutdown. Regular inspection and cleaning or replacement of the nozzle are recommended to maintain efficient operation.
