<p>Cooking appliances including burners particularly configured to improve heating and reduce exposure of the burner above the cooktop include a burner head defining a chamber enclosed by a peripheral wall and a plurality of burner ports communicating between the chamber and the exterior of the head. A burner cap covers the burner head, and the burner head preferably includes extended fingers to improve the dispersion of the burner flame. Preferably, the burner cap conforms with the shape of the burner head. In addition, the burner includes a base for supporting the burner on a cooktop opening. The burner base and the burner head include openings to form a primary flow passage for drawing the flow of gas to the burner. In addition, secondary flow passages communicate with secondary bypass ports formed in the burner head or between the burner head and other burner parts.</p> |
