Delavan 1.10-70-w Oil Burner Nozzle 1.10 Gph 70 Degree Wide Angle

Product Description

The Delavan 1.10-70-W is a residential and light commercial oil burner nozzle designed to deliver precise fuel atomization in oil-fired heating systems. This nozzle carries a flow rate of 1.10 gallons per hour and a 70-degree wide angle spray pattern, making it well suited for forced-air oil furnaces, oil boilers, and water heaters that require consistent, efficient combustion. HVAC technicians and heating contractors rely on nozzles like the 1.10-70-W to maintain proper air-to-fuel ratios, reduce carbon buildup, and keep burner systems running at peak efficiency throughout the heating season. The wide spray pattern distributes atomized fuel oil evenly across the combustion chamber, promoting thorough mixing with combustion air. This leads to cleaner burns, lower stack temperatures, and reduced soot accumulation on heat exchangers and flue passages. Delavan is a globally recognized manufacturer of precision spray nozzles for the heating industry. Their oil burner nozzles are engineered to tight tolerances to ensure repeatable performance across service calls and replacements. The 1.10 GPH flow rate is a common sizing used in mid-range residential oil heating equipment, and this nozzle serves as a direct replacement in many standard burner assemblies. The W designation indicates a wide angle pattern, which is ideal for combustion chambers with larger diameter openings. Proper nozzle selection directly affects combustion efficiency, fuel consumption, and system reliability. Replacing a worn or clogged nozzle with the correct Delavan 1.10-70-W restores proper spray geometry and atomization quality. This nozzle is a standard service part for any HVAC technician working on oil-fired heating equipment.
