Abstract
In a gas burner for introducing a fuel/air mixture into a combustion chamber, a tube is provided for introducing a source of primary air into a core portion of the fuel air mixture. The resulting secondary flame that is produced within the primary flame causes a reduction of NOX gases, which can be attributed to the dispersion of combustion byproducts within the primary flame. In one embodiment, the air supply tube enters the area of the fuel air mixture radially and then turns and extends axially along an extended axis of the burner.
