Delavan 1.10-45-b Type B Solid Cone Oil Burner Nozzle 1.10 Gph 45 Degree

Product Description

The Delavan 1.10-45-b is a Type B solid cone oil burner nozzle rated at 1.10 gallons per hour with a 45 degree spray angle. This nozzle is designed for use in residential and light commercial oil-fired heating systems, including forced air furnaces, boilers, and water heaters. Oil burner nozzles are precision-engineered components that atomize fuel oil into a fine mist before it enters the combustion chamber. Proper atomization is critical for clean, efficient combustion and helps reduce soot buildup, carbon deposits, and fuel waste. The Type B spray pattern produces a solid cone distribution, meaning fuel is distributed evenly throughout the entire cone shape rather than concentrated at the edges. This pattern is well suited for combustion chambers that require a full, uniform flame pattern. The 45 degree angle refers to the spray angle of the atomized fuel cone, which must be matched to the combustion chamber geometry for optimal performance. Using the wrong spray angle can lead to incomplete combustion, increased emissions, and heat exchanger damage. The 1.10 GPH flow rate determines how much fuel is delivered per hour and must match the burner manufacturer specifications for safe and efficient operation. HVAC technicians and oil burner service professionals rely on Delavan nozzles as a standard replacement part during annual tune-ups and service calls. This nozzle is compatible with common oil burner brands and is a direct replacement for worn or clogged nozzles. Replacing the oil burner nozzle annually is a recommended best practice to maintain peak combustion efficiency and extend equipment life.
