Delavan 0.55-60-w 0.55 Gph 60 Degree W All Purpose Oil Burner Nozzle

Product Description

The Delavan 0.55-60-w is a W-pattern all-purpose oil burner nozzle built for residential heating systems. It delivers a flow rate of 0.55 gallons per hour at a spray angle of 60 degrees. HVAC technicians and heating system installers rely on this type of nozzle to atomize fuel oil into a fine mist that ignites cleanly and burns efficiently inside a residential oil-fired furnace or boiler. Proper atomization is critical to combustion quality. A well-matched nozzle reduces soot buildup, improves heat transfer, and lowers the risk of lockouts or misfires during the heating season. The W-pattern designation means this nozzle produces a hollow cone spray with a solid center, which is often referred to as a semi-solid or all-purpose pattern. This pattern works well across a wide range of residential oil burner applications, making it a practical choice when a single nozzle type needs to handle varied firing conditions. The body is constructed from brass, which resists corrosion and holds up to repeated heating cycles. The orifice disc is made from steel, providing durability at the most wear-prone point in the nozzle. A sintered filter is integrated into the nozzle to trap debris before it reaches the orifice, protecting the spray pattern and extending service life. This nozzle is rated for operation at 100 PSI and a temperature of 80 degrees Fahrenheit, matching standard residential oil burner pressure settings. It meets ISO 9001 manufacturing standards, ensuring consistent dimensional accuracy from one unit to the next. Replacing oil burner nozzles annually or at each tune-up is standard practice. Using the correct flow rate and spray angle is essential to matching the burner to the heat exchanger and flue system. Substituting the wrong nozzle can cause incomplete combustion, increased fuel consumption, and carbon deposits on the heat exchanger surfaces.

• W all-purpose spray pattern with 60-degree angle for broad residential compatibility
• Brass body and steel orifice disc for corrosion resistance and long service life
• Integrated sintered filter protects the orifice from debris and maintains spray consistency
