Co-flow burner
Webcapable of sustaining a stable flame with the increased inert gas flow resulting from the use of FGR. When low NOx burners and FGR are used in combination, these techniques are capable of reducing NOx emissions by 60 to 90 percent. Low NOx burners reduce NOx by accomplishing the combustion process in stages. Staging Web1.
