Delavan Oil nozzle 00135-45W1

The Delavan Oil nozzle 00135-45W1 is a fuel nozzle with a capacity of 1.35 gallons per hour and a spray angle of 45 degrees. It features a W spray pattern, which is an all-purpose type that is neither truly hollow nor solid, suitable for various burner air patterns. This nozzle is used for fuel dose adjustment, fuel spraying, flame formation, and fuel economy, while also reducing emissions. It is designed for use in oil burners for heating systems and other devices.

When selecting a replacement oil nozzle of this type, ensure the capacity (in gallons per hour), spray angle, and spray pattern match the burner's requirements. The nozzle must be compatible with the burner's air pattern; W-type nozzles can often replace solid or hollow cone nozzles within a range of 0.40 to 8.00 GPH. Before ordering, verify the nozzle's thread size and dimensions to fit the burner's assembly. Installation involves removing the old nozzle and installing the new one with proper torque, ensuring no debris enters the fuel line.

Common failures of oil nozzles include clogging due to dirt or carbon deposits, which can cause uneven flame, soot formation, or reduced heating efficiency. A worn or damaged nozzle may lead to improper atomization, resulting in incomplete combustion, increased fuel consumption, or burner shutdown. Symptoms may include a pulsating flame, excessive smoke, or the burner failing to ignite. Regular inspection and cleaning or replacement of the nozzle are recommended to maintain optimal burner performance.
