Danfoss Oil nozzle 030H6904

The Danfoss 030H6904 is an oil nozzle with a flow rate of 0.4 GPH (gallons per hour) and a spray pattern marked as H, indicating a hollow spray. It is made of brass and has a conical shape. The nozzle is designed for use in oil burners, where it atomizes fuel for efficient combustion. It features a sintered filter and does not include a safety valve. The net weight is 0.034 kg, and the gross weight is 0.035 kg.

Oil nozzles of this type are selected based on the required flow rate (in GPH), spray angle, and spray pattern (hollow or solid) to match the burner's specifications. The nozzle must be compatible with the burner's fuel pump pressure and the desired combustion characteristics. When installing, ensure the nozzle is clean and properly seated, and use a torque wrench to tighten to the manufacturer's recommended specification. Always compare the nozzle's markings with the old one before fitting.

When oil nozzles of this kind fail or become clogged, the burner may produce an uneven flame, soot, or fail to ignite. The equipment might exhibit reduced heating efficiency or frequent shutdowns. Check the nozzle for blockages or wear, and inspect the spray pattern for irregularities. If the nozzle is damaged or blocked, replace it with a new one of the same specifications.
