A feature of these burners is their structural details, which regulate the intensity and sequence of mixing the fuel with the air flow. Using a ratio of velocities and swirl of inside and outside flows of secondary air, the authors of low-emission burners actually arrange the staged air supply in the flame of a certain burner, and in some cases even the staged fuel supply with the partial NO reduction in each flame.
