6570B .65 GPH 80 Degree Hollow Oil Burner Nozzle Replacement for Delavan for Efficient Combustion

Replacement .65 GPH 80 degree hollow oil burner nozzle, compatible with Delavan models (replacement for 6570B, .6570B, 0006570B1) Product highlights Size and angle: .65 GPH flow rate with an 80 degree flame apex angle for a hollow cone spray pattern. Pattern and performance: Hollow flame pattern that produces a spray with droplets distributed fairly uniformly across the pattern. The spray becomes progressively more hollow at higher flow rates, concentrating droplets toward the outside of the cone for reliable ignition and low-noise combustion. Materials and quality: Manufactured from quality stainless steel and brass and subjected to strict quality testing for dimension and flow consistency. Compatibility: Designed to fit Delavan oil burner nozzles and other compatible burner assemblies that accept this nozzle type. Key benefits Improved ignition: Concentrated droplet distribution on the cone perimeter promotes smooth ignition, especially in larger burners. Efficient combustion: Uniform droplet size and distribution support consistent fuel combustion and reduced flame instability and noise. Durable construction: Stainless steel and brass components offer resistance to wear in routine service conditions and maintain dimensional accuracy over time. Easy replacement: Direct-fit nozzle design simplifies maintenance and routine nozzle replacement. Function details Produces a hollow cone spray that is fairly uniform through the pattern and becomes more hollow as flow rate increases. Particularly suited for burners with a hollow cone air pattern and applicable for throughputs up to 2.00 GPH. Concentration of droplets on the cone outside improves ignition reliability and reduces combustion noise in appropriate burner designs. Typical applications Routine maintenance replacement in residential oil-fired boilers and furnaces that use hollow cone nozzles. Commercial or light industrial burners where smooth ignition and stable combustion are required. System upgrades or repairs on burners compatible with the 6570B .6570B 0006570B1 nozzle specification. What is included One .65 GPH, 80 degree hollow oil burner nozzle manufactured from stainless steel and brass and inspected for flow and pattern accuracy. Compatibility note Fits Delavan-compatible oil burner nozzle fittings specified for .65 GPH 80 degree hollow patterns. Verify model compatibility before installation.
