Danfoss Oil nozzle 030H8914

This Danfoss oil nozzle, SKU 030H8914, is a brass, conical nozzle for fuel oil used in pressure-jet burners. Its operating principle is fuel atomisation. It has a flow rate of 0.65 GPH (0.65 gallons/hour) and a spray pattern marked 'h'. It has no safety valve and uses a sinter filter. Net weight is 0.032 kg and gross weight is 0.034 kg. It is compatible with a pump and solenoid valve.

Oil nozzles of this type are selected by three parameters: flow rate, spray angle and spray pattern, all of which must match the burner data plate. The nozzle is installed at the end of the oil gun, downstream of the pump and solenoid valve. When replacing, verify that the new nozzle's flow, angle and pattern match the original and always follow the burner manufacturer's specification—these nozzles are not interchangeable by thread size alone.

As nozzles of this kind wear, the orifice erodes, altering spray quality and combustion efficiency. A worn nozzle or one with an incorrect pattern can cause sooting, pulsation or unstable ignition.
