Danfoss Oil nozzle 030H8929

The Danfoss 030H8929 is an oil nozzle designed for use in burners to spray fuel into the combustion chamber. It has a flow rate of 1.65 GPH (6.08 kg/h) and features a hollow spray pattern with an H marking. The nozzle is made of brass with a conical shape and includes a sintered filter. Its net weight is 0.034 kg, and gross weight is 0.035 kg. This nozzle type is designated as OD H and does not include a safety valve.

When selecting a replacement oil nozzle of this kind, ensure the flow rate (in GPH or kg/h), spray angle, and spray pattern (hollow or solid) match the burner's requirements. The nozzle type (e.g., OD H) and filter type (e.g., sinter) must be compatible with the fuel and burner design. Installation involves removing the old nozzle and fitting the new one securely, ensuring proper alignment and torque. Always verify the nozzle's specifications against the burner manual before ordering.

Oil nozzles of this kind can fail due to clogging from debris or carbon buildup, leading to poor atomization and incomplete combustion. Symptoms include soot formation, reduced heating efficiency, or uneven flame. A worn or damaged nozzle may cause fuel leakage or pressure drops. Regular inspection and cleaning or replacement are recommended to maintain burner performance.
