Delavan Oil nozzle 00850-80B7

The Delavan Oil nozzle 00850-80B7 is a precision component for oil burners, designed to atomize fuel oil into a fine spray for complete combustion. It has a capacity of 8.5 gallons per hour (GPH) and a spray angle of 80 degrees. The spray pattern is type B, and it is intended for use with fuel oil. This nozzle is suitable for domestic and light commercial oil burners, with a manufacturer code of 00850-80B7 and an article number of 345.892.276. Its flow rate is 8.5 GPH, and it weighs 8.5 kg/h in terms of capacity.

When selecting a replacement oil nozzle of this type, three key parameters must match the burner's data plate: flow rate (in GPH), spray angle, and spray pattern (hollow, solid, or semi-solid). The thread size is standard for this nozzle type, but verify compatibility with the burner's nozzle adapter before installation. Always check the original part number or the burner manufacturer's specification to ensure the exact rating, angle, and pattern are correct.

Oil nozzles of this kind can fail due to clogging, wear, or improper installation, leading to incomplete combustion. Symptoms include sooting, flame pulsation, unstable ignition, or increased fuel consumption. Regular inspection and replacement of the nozzle are necessary to maintain efficient burner operation.
