This nozzle atomizes fuel oil into a fine spray pattern that mixes with combustion air inside the burner chamber. The result is efficient, clean combustion that reduces soot buildup and keeps heat exchangers running at peak condition. HVAC technicians and oil burner service professionals rely on this type of nozzle as a standard replacement part during annual tune-ups and burner service calls.\u003c\/p\u003e\u003cp\u003eThe 0.55 designation refers to the flow rate of 0.55 gallons per hour at 100 PSI nozzle pressure. This low flow rate suits smaller oil-fired furnaces, boilers, and water heaters that require precise fuel delivery for efficient operation. The 80-degree spray angle produces a wide cone pattern well suited for shorter combustion chambers where the flame needs to spread out quickly. The Type A designation identifies this as a hollow cone pattern. A hollow cone nozzle concentrates the fuel spray at the outer edge of the cone, which promotes strong air-fuel mixing and helps produce a stable flame with lower carbon monoxide output.\u003c\/p\u003e\u003cp\u003eDelavan is a well-established manufacturer of oil burner nozzles trusted across the heating industry. Their nozzles are compatible with most major oil burner brands including Beckett, Carlin, Riello, and Wayne. Replacing the nozzle annually is standard practice in oil heating maintenance because worn or clogged nozzles lead to poor combustion efficiency, increased fuel consumption, and excessive smoke. Using the correct flow rate and spray angle is critical to proper burner setup. Always verify the original equipment specifications before installing a replacement nozzle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFlow rate of 0.55 gallons per hour at 100 PSI operating pressure\u003c\/li\u003e\n\u003cli\u003e80-degree hollow cone spray pattern for wide flame spread in shorter combustion chambers\u003c\/li\u003e\n\u003cli\u003eCompatible with Beckett, Carlin, Riello, Wayne, and other major residential oil burners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 0.55-80-A hollow cone oil burner nozzle delivers precise fuel atomization at 0.55 GPH for clean, efficient combustion in residential oil heating systems.
