Abstract
A burner assembly for a gas powered cooking appliance is provided. The burner assembly may include a burner body including a central region and a plurality of radiating extensions extending radially outward from the central region. The burner assembly may include a burner cap with a central region and a plurality of radiating extensions extending radially outward from the central region. The burner cap is positioned on top of the burner body when the burner is assembled. The burner cap may include at least one overhang positioned on the outer perimeter of the central region and between an adjacent pair of radiating extensions. The at least one overhang forms a gap between the exterior wall of the burner body and the interior wall of the overhang. This gap, or flame stabilization chamber, provides for collection of gases and flame that aid in maintaining the flame during low temperature operation.
