Fuel-air mixing and flame stabilization device for a low emission burner with internal flue gas recirculation

A method of operating a flame stabilization apparatus with fuel injection upstream of a torpedo, comprising:

• injecting fuel into an air stream at an entrance to the torpedo from a fuel tube of a burner;
• and
• stabilizing a flame with a flame stabilization plate that includes a plurality of spokes surrounding a fuel plenum, wherein a first group of fuel ports is located in the fuel tube upstream of the torpedo and a second group of fuel ports is located in the flame stabilization plate, and the flame with respect to the flue gas is stabilized at an end of the burner in a discharge zone of a discharge cone.

A flame stabilization apparatus, comprising:

• a flame stabilization plate that includes a plurality of spokes that stabilizes a flame over a range of operations of a burner;
• and
• a discharge cone comprising a discharge zone for the burner, wherein a flame with respect to the flue gas is stabilized at an end of the burner in the discharge zone.
