    • A burner for combusting gas and/or liquid fuel and air in an enclosure includes a burner block of non-combustible material, such as ceramic material, having a central opening therethrough communicating with a combustion zone. The burner block has a plurality of spaced apart recirculation gas passageways paralleled to and spaced from the central opening, each of the recirculation gas passageways having an injection passageway communicating with the block member central opening. Fuel, which may be liquid and/or gas, is injected into said burner block central opening. Venturi action causes furnace gas to be drawn from the cool fringes of the combustion zone through the recirculation gas passageways for passage back into the central opening wherein air and fuel are thoroughly mixed and cooled for combustion within the enclosure. This recirculation system serves to reduce the temperature and oxygen content of the local combustion process to thereby reduce NO.sub.x production. An annular flame director ring positioned within the burner block central opening adjacent to and below the injection passageways augments the Venturi action to increase flow through the recirculation passageways.
    • 用于在外壳中燃烧气体和/或液体燃料和空气的燃烧器包括不燃性材料(例如陶瓷材料)的燃烧器组件,其具有与燃烧区域连通的中心开口。 燃烧器块具有与中心开口平行并间隔开的多个间隔开的再循环气体通道,每个再循环气体通道具有与块构件中心开口连通的注入通道。 可以将液体和/或气体的燃料注入燃烧器中心开口。 文丘里作用导致炉气从燃烧区的冷条纹通过再循环气体通道被抽出,以通过回到中心开口,其中空气和燃料被充分混合并冷却以在外壳内燃烧。 该再循环系统用于降低局部燃烧过程的温度和氧含量,从而减少NOx产生。 定位在燃烧器中心开口内的环形火焰导向器环邻近喷射通道和其下方,增加文丘里作用以增加通过再循环通道的流动。

    • A transmission cable having a nonhalogenated jacket and a nonhalogenated composition for use as a transmission cable jacket. The jacket is prepared from a nonhalogenated polyolefin based formulation having flame retardant, low corrosivity, low toxicity and low smoke characteristics. The jacket material insulates a core transmission medium such as a metallic conductor or optical fiber. The jacket is extruded about the core or insulator during manufacture. The inventive cable has a jacket formed of nonhalogenated polyethylene and nonhalogenated ethylene vinyl acetate and provides a combination of desired mechanical characteristics, improved performance and manufacturing features while eliminating undesirable corrosive products released during a fire.
    • 一种具有非卤素护套的传输电缆和用作传输电缆护套的非卤化组合物。 夹套由具有阻燃性,低腐蚀性,低毒性和低烟特性的非卤代聚烯烃基配方制备。 护套材料将核心传输介质如金属导体或光纤绝缘。 夹套在制造过程中围绕芯或绝缘体挤出。 本发明的电缆具有由非卤代聚乙烯和非卤代乙烯 - 乙酸乙烯酯形成的护套,并提供期望的机械特性,改进的性能和制造特征的组合,同时消除在火灾期间释放的不期望的腐蚀性产品。
