摘要： A burner having an elongate, generally tubular sheet metal body having an inlet end, a closed distal end and a tubular segment extending between the ends. The inlet end is formed to define a gas orifice holder which is adapted to mount a gas orifice element. The inlet end is further formed to define at least one primary air opening arranged to admit primary air from a source of primary air. Rows of flame ports are defined in the tubular segment and are arranged to create a desired predetermined flame pattern. When used as a fireplace burner the flame ports may be slot-like in construction and include tabs which determine the effective size of the ports. In a fireplace application, flame ports located below a crossover log, are eliminated and/or formed of reduced size, thus providing a flame of lower height and/or less intensity, thus substantially eliminating sooting. When used as a premix-type burner, a source of primary air under pressure is delivered to the inlet end of the burner and compensates for the restriction posed by the bluff structure, resulting in a blue flame.

摘要： A gas burner that produces a yellow flame for use in a fireplace assembly, including front and rear non-combustible logs and a cross-over log supported atop the front and rear logs. The burner includes an elongate, generally tubular sheet metal body having an inlet end, a closed distal end and a tubular segment extending between the ends. The inlet end is formed to define a gas orifice holder which is adapted to mount a gas orifice element and to define at least one primary air opening arranged to admit combustion air into the tubular burner segment. A bluff body is located downstream from the gas orifice element and is positioned such that gas emitted by the orifice impinges on the bluff body. Rows of slot-like flame ports are defined in the tubular segment and are arranged to create a desired predetermined flame pattern and include tabs which determine the effective size of the ports. In regions of the burner located below the crossover log, flame ports are eliminated and/or formed of reduced size, thus providing a flame of lower height and/or less intensity, thus substantially eliminating sooting. In alternate embodiments, the bluff body is formed by a pair of confronting depressions that define a pair of venturi channels which define the mixing chamber. In another embodiment, the confronting depressions are spaced apart and mount a cylindrical bluff element therebetween. The use of venturi channels eliminates or substantially reduces the incidence of light back.
摘要翻译：一种气体燃烧器，产生用于壁炉组件的黄色火焰，包括前后不可燃原木，以及支撑在前后原木顶部的交叉测井。燃烧器包括细长的，大致管状的金属片体，其具有入口端，封闭的远端和在端部之间延伸的管状区段。入口端形成为限定气体孔保持器，其适于安装气体孔口元件并且限定至少一个主要空气开口，布置成将燃烧空气吸入管状燃烧器段。非流线形体位于气体孔元件的下游并且被定位成使得由孔口发射的气体撞击在非流线体上。狭槽状火焰口的行被限定在管状段中，并且被布置成产生期望的预定火焰图案，并且包括确定端口的有效尺寸的突片。位于交叉点下方的燃烧器区域，火焰口被消除和/或形成为减小的尺寸，从而提供较低高度和/或较小强度的火焰，从而基本上消除了烟炱。在替代实施例中，非流线形体由一对相对的凹陷形成，所述凹陷限定了限定混合室的一对文丘里管道。在另一个实施例中，相对的凹陷间隔开并且在其间安装圆柱形虚张声势元件。文丘里通道的使用消除或大大降低了光回射的发生率。
