Delavan 1.00 GPH 80° A Hollow Cone Oil Burner Nozzle 10080A Hollow Cone Nozzle Hollow Cone Nozzle
(Type A) Hollow cone nozzles can be used in burners with a hollow air pattern and also for use in small burners (those firing 1.00 GPH and under), regardless of air pattern. Hollow cone nozzles generally have more stable spray angles and patterns under adverse conditions than solid cone nozzles of the same flow rate. This is an important advantage in fractional gallonage nozzles where high viscosity fuel may cause a reduction in spray angle and an increase in droplet size. Type A nozzles produce a spray which delivers fine droplets outside the periphery of the main spray cone. These fine droplets greatly enhance ignition and create a stable flame for use with flame retention burners. One Gallon Eighty Degree A Hollow Spray Nozzle
