Description

The Danfoss 030H8906 is an oil nozzle with a flow rate of 0.45 GPH, a spray angle of 80°, and an H spray pattern. It is used in oil-fired burners to atomise fuel oil into a fine spray for combustion. The 0.45 GPH rating defines the volume of oil delivered per hour at the nozzle's rated pressure. The 80° spray angle determines the width of the cone formed by the atomised oil. The H pattern denotes the specific distribution of fuel within that cone.

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: nozzles are commonly secured by a threaded body or a retaining nut, and the seat and thread must correspond to the nozzle holder. Before ordering, compare the markings on the existing nozzle and the burner's technical data. The pump pressure stated for the appliance must also be observed, as flow rate depends on it.

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, pulsate, or run with an unstable flame. A blocked or worn nozzle can also cause incomplete combustion and soot deposits on the boiler surfaces. Checking the spray pattern, the nozzle strainer, and the combustion readings is the usual diagnostic step.
