Description

This is a Danfoss oil nozzle with a flow rate of 0.85 GPH, a spray angle of 80°, and a B spray pattern. It is used to atomise fuel oil in a burner, forming the spray that is mixed with air and ignited. The 0.85 GPH rating defines the volume of oil delivered per hour at the reference pressure. The 80° angle sets the width of the spray cone, and the B pattern denotes the distribution of droplets within that cone. The item is identified by SKU 030B0206.

Choosing and fitting

Nozzles of this type are selected by matching the flow rate, spray angle, and spray pattern to the burner manufacturer's specification, and by confirming the thread and mounting form fit the nozzle holder. Before ordering, compare the markings on the existing nozzle with the required values and check that the seat and the mating face in the holder are clean and undamaged. Installation requires the correct tightening torque and correct seating, as an ill-fitting nozzle alters the spray and combustion.

Signs of failure

Nozzles of this kind commonly fail through clogging of the internal passages or wear of the orifice, which changes the flow rate and the spray shape. On the equipment this appears as unstable combustion, a smoky or yellow flame, soot deposits, or difficulty in starting and maintaining the flame. Checking involves inspecting the nozzle for blockage or damage, verifying the spray pattern and angle, and comparing the measured flow rate with the rated value.
