Abstract
An improved bar burner is provided for use in a cooking grill having a top cooking area. The bar burner includes an elongate body having a pair of curved ends and a pair of substantially parallel sidewalls extending between the curved ends. A plurality of holes is distributed along each side wall for flowing combustible gas from the interior to the exterior of the body. Each curved end also has a plurality of holes for flowing gas to the exterior of the body. The holes in each curved end are arranged to define an end zone and a pair of angularly facing side zones. The holes in the side zones have enlarged cross-sectional areas, thereby providing improved heat rejection. The cross-sectional areas of the holes defining the angularly facing side zones are generally equal to one another and greater than the cross-sectional areas of the holes distributed along each side wall and in the end zones. When used in a rectangular burner kettle, the flames at the angularly facing side zones reject heat toward the kettle corners to more nearly equalize the temperature across the top cooking area. Several preferred embodiments are disclosed.
