    • A gas burner (11) for a charcoal grill having a bowl (12) includes an elongated burner tube (30) secured to the bowl and passed through an opening (36) in the bowl (12) so as to be positioned in a substantially horizontal manner below and substantially parallel to a bed of charcoal supported on a charcoal support grid (18). The burner has a propane tank (42) connected to the free end thereof outside the bowl (12) and has air intake openings (44) in the tube (30) adjacent the free end. A venturi section (46) is formed into the tube (30) downstream of the air intake openings (44) and elongated diametrically-opposed, horizontal slots (50) defining the gas exit ports are positioned downstream of the venturi section (46). An igniter assembly (52) having its electrode (56,60) extending through an opening into the tube (30) is located between the venturi section (46) and the slots (50) to ignite the flowing gases. The positioning of the electrode (56,60) within the tube (30) prevents flash-back through the air intake openings (44).
    • 一种用于具有碗(12)的木炭格栅的气体燃烧器(11),包括一个细长的燃烧器管(30),其固定在碗上并通过碗(12)中的一个开口(36),以便基本上 水平方式在支撑在木炭支撑网格(18)上并基本平行于木炭床。 燃烧器具有连接到碗(12)外部的自由端的丙烷罐(42),并且在管(30)中邻近自由端具有进气口(44)。 文丘里管部分(46)形成在进气口(44)下游的管(30)中,限定气体出口的细长直径相对的水平槽(50)位于文氏管部分(46)的下游。 具有延伸通过管(30)的开口的电极(56,60)的点火器组件(52)位于文氏管部分(46)和狭槽(50)之间,以点燃流动的气体。 电极(56,60)在管(30)内的定位防止通过进气口(44)闪回。
