Abstract:
A stacked dual gas burner assembly, comprising:(a) a main burner having a main burner radius and a plurality of main burner ports formed on a radially outward facing surface thereof;(b) a second burner having a second burner radius and a plurality of second burner ports formed on a radially outwardly facing surface thereof, wherein the second burner is positioned coaxially with and below the main burner in the gas burner assembly, and wherein the second burner radius is smaller than the main burner radius such that an overhanging edge of the main burner overhangs the second burner adjacent to the second burner ports to provide recirculation underneath the overhanging edge to stabilize flames produced from the second burner ports to help maintain flame attachment at the second burner ports.
