    摘要： A fuel fired burner comprises a chamber for receiving a premixture of fuel and air. A wall of the chamber is in the form of a flamestrip provided with a plurality of elongate slots extending through the wall. Each slot has an inlet portion which converges to an end leading to a substantially constant dimension portion. The pitch of the slots along the chamber wall is P, the width of each slot is w, and the length of the constant dimension portion is L. The dimensions of the flamestrip are arranged such that L/w.gtoreq.10 and P/w.gtoreq.2. A burner including such an arrangement reduces the likelihood of resonant combustion noise being generated when enclosed within a heating appliance.

    摘要： A high load gas combustion apparatus for use mainly in domestic combustors which require a low noise level and compactness. Some of the air for burning supplied from a fan is suctioned to fuel gas jetted through a nozzle to produce a mixture in a mixing tube section, which is then introduced to a mixture chamber defined by a burner body having a uniform shape in the lengthwise direction. The mixture flows into a downstream combustion chamber at a relatively low speed through a flame port section which is incorporated in the burner body on the downstream side of the mixture chamber, and which comprises a number of flame ports having a large opening ratio. The majority of air is supplied to air chambers on both sides of the mixture chamber partitioned by the burner body therefrom. The air chambers and the combustion chamber are partitioned by an air jet plate which includes a number of air ports arranged in wave-like form in the oblique portion thereof and a number of flame retention air ports arranged in the lengthwise direction of the flame port section. Some of the air supplied to the air chambers is supplied under reduced pressure to a flame retention chamber, which is constituted by a recess formed in a part of the burner body on either side of the flame port section, through small gaps formed between the air jet plates and the side wall of the recess, and then flows into the combustion chamber at a lower speed from both sides of the flame port section through the flame retention air ports, thus ensuring flame retention. The majority of the air supplied to the air chambers flows into the combustion chamber through the air ports so as to cross the direction of flow of the mixture for producing a steady flame along the air ports arranged in zigzag form, thus greatly enlarging the combustion reaction area.

    摘要翻译： 一种高负荷气体燃烧装置，主要用于需要低噪音水平和紧凑性的家用燃烧器。 从风扇供给的一些用于燃烧的空气被吸入通过喷嘴喷射的燃料气体，以在混合管部分中产生混合物，然后将其引入由长度方向具有均匀形状的燃烧器主体限定的混合室 。 混合物通过火焰口部分以相对低的速度流入下游燃烧室，该火焰口部分并入混合室下游侧的燃烧器本体中，并且包括多个具有大开口比的火焰口。 大部分空气被供给到由燃烧器本体分隔开的混合室的两侧的空气室。 空气室和燃烧室被空气喷射板隔开，空气喷射板包括在其倾斜部分中以波浪形形式布置的多个空气端口和沿火焰端口部分的长度方向布置的多个火焰保持空气端口 。 供给到空气室的一部分空气被减压地供给到通过形成在火焰口部分两侧的燃烧器主体的一部分中的凹部，形成在空气之间的小间隙的阻燃室 喷射板和凹槽的侧壁，然后通过火焰保持气孔从火焰口部分的两侧以较低的速度流入燃烧室，从而确保火焰保持。 供应到空气室的大部分空气通过空气口流入燃烧室，从而跨过混合物的流动方向，沿着以锯齿形布置的空气端口产生稳定的火焰，从而大大地扩大了燃烧反应 区。
