Abstract: A gas stove burner has a base having an annular outer edge and a lower ring sitting on the base, forming therewith a lower compartment, and having an outer edge forming with the base outer edge an outwardly open annular slot communicating with the lower compartment. An upper ring sitting on the lower ring forms therewith an upper compartment and has an outer edge forming with the lower-ring outer edge an array of outwardly open holes communicating with the upper compartment. The upper-ring outer edge has a diameter generally equal to a diameter of the lower-ring outer edge. A gas/air mixture is fed to each of the compartments so that the gas will issue from the holes to form an upper flame and from the slot to form a lower flame of substantially the same diameter.
