Delavan 1.00-80-w Oil Burner Nozzle 1.00 Gph 80 Degree Hollow Cone

Product Description

The Delavan 1.00-80-w is an oil burner nozzle rated at 1.00 gallons per hour with an 80-degree spray angle and a hollow cone (W-type) spray pattern. It is designed for residential and light commercial oil-fired heating systems. HVAC technicians and heating equipment service pros rely on this nozzle for accurate fuel atomization in forced-air furnaces, boilers, and water heaters that run on No. 2 fuel oil. The green vial color code identifies the flow rate at a glance, making field identification fast during service calls. Proper nozzle selection is critical to combustion efficiency. The spray angle, flow rate, and pattern type must match the burner manufacturer specifications to achieve clean ignition, stable flame, and low stack emissions. The 80-degree angle is a common specification found in many residential oil burner applications. The W hollow cone pattern distributes fuel in a ring-shaped mist, which works well with most standard residential oil burner heads. At the rated operating pressure of 100 PSI, this nozzle delivers a consistent 1.00 GPH flow, which corresponds to approximately 140,000 BTU per hour of fuel input when burning No. 2 fuel oil. Delavan is a leading name in oil burner nozzle manufacturing, and their nozzles are built to tight tolerances to ensure repeatable performance from unit to unit. This nozzle is an all-purpose style, meaning it is compatible with a wide range of burner brands and models. It is a direct-replacement nozzle used during annual tune-ups, combustion analysis service, and emergency no-heat calls. Replacing the oil burner nozzle annually is standard industry practice to maintain peak combustion performance and prevent coke buildup in the combustion chamber.
