Delavan Oil nozzles 01800-45A0

The Delavan 18.00GPH, 45A oil nozzle is a component designed for use in oil burners, with a capacity of 18 gallons per hour and a spray angle of 45 degrees. It features a hollow-cone spray pattern (type A), which is suitable for burners with a hollow cone air pattern and throughputs up to 2.00 gph. This nozzle type concentrates droplet distribution on the outside of the cone, promoting good ignition and low-noise combustion. The article numbers for this item are 345.892.291 and 01800-45A0.

When selecting a replacement oil nozzle of this kind, ensure that the capacity (in GPH), spray angle, and spray pattern type match the burner's requirements. The nozzle must be compatible with the burner's air pattern and throughput range. Installation involves removing the old nozzle and fitting the new one securely, ensuring proper alignment and torque.

Common failure modes for oil nozzles include clogging, wear, or damage, which can lead to poor combustion, soot formation, or ignition issues. Symptoms may include uneven flame, increased fuel consumption, or burner shutdown. Regular inspection and cleaning or replacement of the nozzle are recommended to maintain efficient operation.
