Name: Danfoss Oil nozzle 1.35GPH,80H 030H8926
Brand: Danfoss
SKU: 030H8926

Flow rate

1.35 GPH

Spray angle

80 °

Spray pattern

Description

This is an oil nozzle with a flow rate of 1.35 GPH, a spray angle of 80 °, and an H spray pattern. It is used in oil burners to atomise fuel into a fine spray for combustion. The 80 ° angle defines the width of the spray cone, while the H pattern denotes the distribution of fuel within that cone. The 1.35 GPH rating specifies the volume of oil delivered per hour at the nozzle's rated pressure.

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. The mounting form must also match: most oil nozzles use a standard threaded body, but the thread size and sealing face can vary between burner models. Before ordering, compare the existing nozzle's markings and measure the thread and overall length against the replacement. The pump pressure and the burner's combustion settings must correspond to the nozzle's rated flow.

Signs of failure

Nozzles of this kind commonly fail through clogging of the internal filter or orifice, wear of the metering passages, or damage to the sealing face. When this happens, the burner may produce a weak, pulsating, or uneven flame, fail to ignite, or emit smoke and soot. A blocked or worn nozzle can also cause delayed ignition or a noticeable drop in heat output. Check the nozzle for visible debris, damage, or wear, and compare the flame shape and combustion readings against the burner's specification.
