Delavan Oil nozzle 02800-45B0

The Delavan Oil nozzle 02800-45B0 is a component for diesel burners, designed to atomize fuel for combustion. It has a capacity of 28 gallons per hour and a spray angle of 45 degrees. The spray pattern is type B, which is a solid-cone pattern that distributes droplets uniformly, becoming more hollow at higher flow rates. This nozzle is intended for use in larger burners to provide smooth ignition and efficient combustion.

Oil nozzles of this type are selected based on the burner's required flow rate, spray angle, and spray pattern. The flow rate, typically measured in gallons per hour (GPH), must match the burner's capacity. The spray angle determines the shape of the fuel spray and must align with the combustion chamber design. The spray pattern (e.g., solid or hollow cone) affects fuel distribution and must be chosen according to the burner's specifications. Installation involves removing the old nozzle and installing the new one with proper torque, ensuring no debris enters the fuel line.

When oil nozzles of this kind fail, common issues include clogging due to dirt or carbon deposits, leading to poor atomization and incomplete combustion. This can result in soot buildup, reduced efficiency, and increased emissions. Other symptoms may include uneven flame, pulsation, or difficulty igniting. Regular inspection and cleaning or replacement of the nozzle are necessary to maintain proper burner operation.
