Description

This is a Danfoss oil nozzle with a flow rate of 1.2 GPH, a 45 ° spray angle and an S spray pattern. It is used in oil-fired burners to atomise the fuel into a fine spray before combustion. The 1.2 GPH rating defines the volume of oil delivered per hour at the reference pressure. The 45 ° angle sets the width of the spray cone, and the S pattern denotes a solid spray. The item is identified by the SKU 030F4923.

Choosing and fitting

Nozzles of this type are selected by matching the flow rate, spray angle and spray pattern to the burner and combustion chamber requirements. The mounting form and thread must also match the nozzle holder, and the correct seating must be confirmed before tightening. Before ordering, compare the markings on the existing nozzle with the required specification.

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 poor flame, smoke, soot or ignition faults, and the combustion readings may drift. Check the nozzle for blockage or wear and compare the spray pattern and flow rate against the specification.
