Abstract:
1. A gas burner comprising: a tube mixer adapted to mix a gas fuel with air; an internal chamber comprising an internal plateau configured to reduce chamber volume and increase a flow rate of a mixture from the tube mixer; a cap over the internal chamber; one or more port zones in the periphery of the internal chamber, comprising two or more principal ports, two or more secondary ports complementing said principal ports and allowing flame transfer between the principal ports; and one or more flame transfer ports located in at least one of the ends of said one or more port zones and each configured to produce a flame dart; wherein said principal ports have a port area in a range from 0.00775 square inches to 0.0109 square inches; wherein said secondary ports have a substantially constant port area in a range from 0.00465 square inches to 0.0093 square inches; and wherein said flame transfer ports have a port area in a range from 0.00155 square inches to 0.00465 square inches; wherein each principal port comprises a principal port longitudinal axis, wherein each flame transfer port comprises a flame transfer port longitudinal axis, and wherein an angle between a flame transfer port longitudinal axis and an adjacent principal port longitudinal axis within a same port zone is different than angles between adjacent principal port longitudinal axes in the same port zone, and wherein the flame transfer port longitudinal axis is angled to diverge away from the adjacent principal port longitudinal axis and toward another gas burner so that the flame transfer port is conducive to a flame transfer between the gas burner and said another gas burner wherein each flame transfer port comprises a groove concentric with the flame transfer port longitudinal axis and disposed within a horizontal fan, wherein the horizontal fan spans between 70 and 100 degrees from the adjacent principle port longitudinal axis.
