Abstract
An improvement to conventional atmospheric gas burners particularly advantageously applied to the type used as surface heating units in gas cooking appliances such as ranges and cooktops, which typically comprise a burner head having a plurality of primary burner ports formed at port locations equally spaced about the periphery of the burner head. Improvement is realized by not forming primary burner ports at selected ones of the equally spaced port locations. The unused port locations are selected so as to separate the primary ports into groups. The reduction in the number of ports reduces the total port area thereby reducing the amount of primary air entrained in the air/gas mixture delivered to the burner. In addition the resulting spacing of the groups of ports has the effect of reducing the amount of secondary air per port relative to that which would be entrained by the same number of ports, if equally distributed about the periphery. The net result being more controlled combustion under normal operating conditions and in particular under delayed ignition conditions.
