Abstract
A stacked dual gas burner which achieves good performance at high firing rates as well as good simmer performance at low firing rates. The stacked dual gas burner includes a main burner and a second (simmer) burner. The main burner and second burner are positioned in a stacked relation in a burner assembly, with the second burner positioned coaxially with and below the main burner. The second burner radius is smaller than the main burner radius, such that a portion of the main burner overhangs the second burner adjacent to the second burner ports. Recirculation underneath the overhanging edge of the main burner above the simmer burner ports helps maintain flame attachment at the second burner ports. A valve may be used to provide separately controllable flows of fuel to each of the main and second burners.
