Delavan Oil nozzles 00850-45B7

The Delavan 00850-45B7 is an oil nozzle with a capacity of 8.5 gallons per hour and a spray angle of 45 degrees. It features a B spray pattern, which is designed for specific combustion characteristics. This nozzle is used in burners to regulate fuel flow and atomize fuel for efficient mixing with air. It contributes to stable flame formation and helps reduce emissions by optimizing the combustion process.

When selecting a replacement oil nozzle of this type, ensure the capacity, spray angle, and spray pattern match the burner's requirements. The nozzle must be compatible with the burner's fuel pump pressure and the desired firing rate. Installation involves removing the old nozzle and installing the new one with the correct torque, ensuring the O-ring or gasket is in place to prevent leaks.

Common failure modes for oil nozzles include clogging due to debris or carbon buildup, which can cause uneven flame, soot formation, or incomplete combustion. A worn or damaged nozzle may lead to poor atomization, resulting in a yellow flame, increased fuel consumption, or burner shutdown. Regular inspection and cleaning or replacement are necessary to maintain proper burner operation.
