FRAC fuel oil burners are available in two versions.
The NIR/4T model operates with injections of oil atomized at a variable pressure of up to 80 bar. Each unit can feed between 6 and 16 firing points.
The ASN/7 model operates with gasified fuel oil with the aid of air supplied by a fan. Each unit can feed between 6 and 20 firing points, preferably divided into two firing rows.
The NIR/4H model (Hoffman kilns) operates with light or heavy oil that has been suitably heated.
In both types of burners, the amount of fuel supplied to the kiln for every single firing point is strictly volumetric, that is to say it does not depend on the viscosity, temperature or pressure of the oil.
