Delavan Oil nozzle 33769-089

The Delavan 33769-089 is an oil nozzle with a flow rate of 22 gallons per hour and a spray angle of 80 degrees. It features a BPS spray pattern and is designed for use in oil-fired burners. This nozzle atomizes fuel into a fine spray to ensure complete and stable combustion. It is a precision component that directly affects flame shape and combustion efficiency.

When selecting a replacement oil nozzle, the flow rate, spray angle, and spray pattern must match the burner's data plate specifications. The thread size must also be compatible with the burner assembly. Incorrect selection can lead to sooting, pulsation, or unstable ignition. Always refer to the burner's original manufacturer specification for the correct nozzle choice.

A worn or incorrect oil nozzle can cause incomplete combustion, leading to soot buildup, pulsation, or unstable ignition. The flame shape may become irregular, and combustion efficiency may decrease. Regular inspection and replacement of the nozzle are necessary to maintain proper burner operation.
