Delavan Oil nozzle 00450-90B7

The Delavan Oil nozzle 00450-90B7 is a precision component designed to atomize fuel oil into a fine spray for efficient combustion in burners. It has a capacity of 4.5 gallons per hour (GPH), a spray angle of 90 degrees, and a spray pattern type B. This nozzle is categorized under oil nozzles and is identified by the manufacturer code 00450-90B7. It is a consumable part that must be selected based on flow rate, spray angle, and spray pattern to ensure proper flame characteristics.

When selecting a replacement oil nozzle of this type, verify that the flow rate (in GPH or kg/h at reference pressure), spray angle, and spray pattern (hollow, solid, or semi-solid) match the burner's data plate. The thread size must also be compatible with the burner. Incorrect selection can lead to sooting, pulsation, or unstable ignition.

Oil nozzles of this kind can fail due to clogging, wear, or damage, leading to poor atomization. Symptoms include soot formation, flame instability, pulsation, or incomplete combustion. Check the nozzle for blockages or erosion and replace if necessary.
