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.
Claims13
A NOX reduction apparatus for use in a furnace having a bummer for delivering a premixed fuel/air mixture to a combustion chamber comprising:
- a conduit extending into a flame resulting from the ignition of said fuel/air mixture for introducing primary air into a central core portion of said flame to thereby affect the combustion process.
A method of reducing NOX in a gas burner of the type used in conjunction with a combustion chamber of a heat exchanger and having an inlet opening for the introduction of a fuel/air mixture into said combustion chamber, comprising the step of:
- introducing a source of primary air into a central core portion of a flame resulting from the ignition of said fuel/air mixture to thereby affect the combustion process.
