-
Mainly used on burners with a hollow cone air pattern and for throughputs up to 2.00 GPH
-
The droplet distribution is concentrated on the outside of the cone and results in good ignition and low-noise combustion
-
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.
