    • A low NOx combustion process and burner apparatus in which a mixture of a primary fuel and air, with the air in excess of the stoichiometric requirement, is passed to a surface burner element. The mixture is distributed over the downstream side of the element where it is combusted in a primary combustion zone. Secondary fuel is mixed with surface combustion products from the primary zone and then combusted in a secondary combustion zone with a portion of excess oxygen from the surface combustion products. In certain embodiments the temperature of surface combustion products is reduced by heat transfer to the surface burner element, and in another embodiment by heat transfer to a screen or other element placed within the primary combustion zone, from which the heat is then extracted to a load, and in another embodiment by mixing the additional fuel or combustion products with cooled furnace gases. In other embodiments the placement of the secondary fuel jets is varied to achieve different combustion results.
    • 低NOx燃烧过程和燃烧器装置,其中主要燃料和空气与空气超过化学计量要求的混合物通过表面燃烧器元件。 混合物分布在元件的下游侧,在主燃烧区内燃烧。 二次燃料与来自主要区域的表面燃烧产物混合,然后在二次燃烧区域与来自表面燃烧产物的一部分过量的氧气一起燃烧。 在某些实施方案中,表面燃烧产物的温度通过传递到表面燃烧器元件的热量而减少,而在另一个实施方案中,通过传热到放置在主燃烧区域内的筛网或其它元件的热量传递到负载 ,并且在另一个实施方案中,通过将附加燃料或燃烧产物与冷却的炉气混合。 在其他实施例中,二次燃料喷射器的布置被改变以实现不同的燃烧结果。

    • An improved construction for the burner of a gas-fired, radiant heater in which a plurality of reverberator, combustion and guard grids are attached over the open face of a shaped plenum enclosure with common fasteners positioned around the periphery of and outside of the plenum. Between the grids and the fuel entrance to the plenum is a novel baffle plate secured within the plenum enclosure which acts to diffuse the fuel-air stream passing towards the grids and to thermally separate the rear of the plenum from the combustion area, thereby improving the directional heating characteristics of the device.
    • 一种用于燃气式辐射加热器的燃烧器的改进的结构,其中多个混响器,燃烧和防护网格被安装在成形气室外壳的敞开的表面上,其具有定位在气室周围和外部的共同紧固件。 在栅格和通向气室的燃料入口之间是一个新颖的挡板,其固定在增压室外壳内,其作用是扩散通向栅格的燃料 - 空气流,并将集气室的后部与燃烧区域分开,从而改善 设备的定向加热特性。

    • A radiant burner includes a housing for receiving a combustible air and fuel mixture and a combustor unit formed to include an open-space combustion chamber having a top opening and passageways for communicating the combustible air and fuel mixture from the housing to the open-space combustion chamber. The combustor unit is a block of insulation material formed to include a cavity defining the open-space combustion chamber and a plurality of apertures defining the passageways. The combustible air and fuel mixture extant in the open-space combustion chamber is ignited to produce a flame. The top opening of the open-space combustion chamber is covered to define a flame retention region therein so that the flame is stabilized in and contained wholly within the open-space combustion chamber. The cover is provided by a radiant member having a heat-receiving surface communicating with the underlying flame produced in the open-space combustion chamber and blocking passage of the flame through the radiant member and a heat-radiating surface emitting flameless thermal radiation to heat a product positioned above the radiant member.
    • 辐射燃烧器包括用于接收可燃空气和燃料混合物的壳体和形成为包括具有顶部开口和通道的开放空间燃烧室的燃烧器单元,所述开放空间燃烧室具有用于将可燃空气和燃料混合物从壳体连通到开放空间燃烧 室。 燃烧器单元是形成为包括限定开放空间燃烧室的空腔和限定通道的多个孔的绝缘材料块。 在开放空间燃烧室中存在的可燃空气和燃料混合物被点燃以产生火焰。 开放空间燃烧室的顶部开口被覆盖以在其中限定火焰保持区域,使得火焰稳定在整个开放空间燃烧室内并且容纳在其中。 所述盖由辐射构件提供,所述辐射构件具有与在所述开放空间燃烧室中产生的下面的火焰相连通的受热表面,并且阻挡所述火焰穿过所述辐射构件,以及发射无焰热辐射的热辐射表面以加热 产品位于辐射构件上方。
