Abstract: A ribbon port burner for a gas range comprises a base defining a gas inlet portion and a gas plenum portion. The gas plenum is defined by a bottom wall portion which terminates at its outer periphery in generally vertical outer side walls. The burner also includes a cap which is positioned in fixed spaced relation to the bottom wall such that the cap forms an upper wall of gas plenum portion. In this position the cap's relation to the side walls defines a ribbon port of essentially constant cross-sectional area continuously around the periphery of the burner. The burner also includes an ignition port in the bottom wall for accommodating insertion of an ignition system within the plenum. Preferably, a gas ignition portion is defined within the gas plenum portion defining a segregated volume. The burner side walls terminate in an acutely angled surface, as does the outer portion of the lower surface of the cap, such that an essentially constant cross sectional area is maintained to form the ribbon port.
