Danfoss Oil burner nozzle 030H4912

The Danfoss 030H4912 is an oil burner nozzle with a flow rate of 0.6 GPH (2.37 kg/h). It features a hollow spray pattern and a conical shape, made from brass. The nozzle type is OD H, and it includes a sinter filter. Its net weight is 0.000034 kg, and gross weight is 0.000035 kg. This component is designed to atomize fuel oil for efficient combustion in burners.

When selecting a replacement oil nozzle of this kind, ensure the flow rate (GPH or kg/h), spray angle, and spray pattern (hollow or solid) match the burner's requirements. The nozzle thread size and type must also be compatible with the burner assembly. Installation typically involves removing the old nozzle and tightening the new one to the specified torque, avoiding over-tightening.

Common failure modes for oil nozzles include clogging due to debris or carbon buildup, which can cause uneven flame, soot formation, or reduced heating output. A worn or damaged nozzle may lead to poor atomization, resulting in incomplete combustion and increased fuel consumption. Regular inspection and cleaning or replacement are recommended when these symptoms appear.
