Delavan Oil burner nozzles 02000-45B0

The Delavan 02000-45B0 is an oil burner nozzle with a capacity of 20 gallons per hour and a spray angle of 45 degrees. It features a B solid-cone spray pattern, which provides uniform droplet distribution for smooth ignition and efficient combustion. This nozzle is suitable for use in larger burners where consistent fuel atomization is required. Its article number is 345.892.214.

When selecting a replacement oil nozzle, ensure that the capacity (GPH), spray angle, and spray pattern type match the original specifications. The nozzle must be compatible with the burner's fuel pump pressure and the combustion chamber design. Installation involves removing the old nozzle and installing the new one with the correct torque, ensuring the O-ring or gasket is in good condition.

Common failure modes for oil nozzles include clogging due to dirt or debris, which can cause uneven flame, soot formation, or incomplete combustion. A worn or damaged nozzle may result in a pulsating flame, increased fuel consumption, or difficulty igniting. Regular inspection and cleaning or replacement of the nozzle are recommended to maintain burner efficiency.
