Description

The Danfoss 030F4914 is an oil nozzle with a flow rate of 0.65 GPH, a 45 ° spray angle, and an S spray pattern. It is used in oil burners to atomise fuel into a fine spray for combustion. The 0.65 GPH rating defines the volume of oil delivered per hour at the nozzle's rated pressure. The 45 ° angle sets the width of the spray cone, and the S pattern denotes a solid spray shape.

Choosing and fitting

Nozzles of this type are selected by matching the flow rate, spray angle, and spray pattern to the burner's requirements. The mounting form and thread must match the nozzle adapter or holder on the burner. Before ordering, compare the existing nozzle's markings and dimensions with the replacement. The pump pressure and filtration should also be checked, as they affect atomisation.

Signs of failure

Nozzles of this kind can clog, wear at the orifice, or develop a distorted spray pattern over time. When this happens, the burner may produce a smoky flame, fail to ignite, or run erratically. A fitter should check for carbon deposits, inspect the spray shape, and verify the flow rate against the burner specification.
