摘要: A gas burner having first flame openings for discharging a stable and self-combustible high-concentration gas and second flame openings for discharging an unstable and non-self-combustible low-concentration gas, with the first and second flame openings being disposed alternately with each other. The effect of stable flame formations at the first flame openings assists stabilization of flame formations at the second flame openings adjacent thereto. Consequently, the gas burner as the whole may have a high air excess ratio to reduce its NOx generation and to prevent incomplete combustion. Further, if a rectifying member is provided in the second flame opening, it becomes possible to enlarge the opening area of the second flame opening without disturbing its flame formation, whereby the burner will achieve further reduction in NOx generation and combustion noise and also improvements in its combustion load and ignition performance.

摘要: A surface combustion type burner with air supply entirely as primary air has metallic netting defining a combustion surface, and is characterized in that in close supporting contact behind the metallic netting, substantially all over the entire rear surface of the metallic netting, there is disposed a punched or perforated metal base which has an open or void perforation ratio smaller than that of the metallic netting.

摘要翻译: 一种具有用于排出稳定且可自燃的高浓度气体的第一火焰开口和用于排出不稳定和不可燃低浓度气体的第二火焰开口的气体燃烧器,其中第一和第二火焰口与每个火焰开口交替设置 其他。 在第一火焰开口处稳定的火焰形成的作用有助于在与其相邻的第二火焰开口处的火焰形成的稳定。 因此,气体燃烧器整体可能具有高的空气过剩比率,以减少其NOx的产生并防止不完全燃烧。 此外,如果在第二火焰开口中设置整流部件,则可以扩大第二火焰开口的开口面积而不会妨碍其火焰形成,由此燃烧器将进一步降低NOx生成和燃烧噪声,并且还可以改善 其燃烧负荷和点火性能。
