    • An industrial waste management facility for disposing of spent potlining includes a co-current gas fired rotary kiln (10) for containing a molten pool (15) of spent potlining throughout the entire length of the rotary kiln (10) from the inlet (12) to the outlet, an ash quencher and cooler (33) for receiving molten residue from the discharge end of the rotary kiln, a secondary combustion chamber (34), and a down-draft transition chamber (32) for channeling discharge gases from the rotary kiln to the secondary combustion chamber. Pneumatic injection slingers (2, 4) feed and distribute spent potlining into the inlet end of the rotary kiln. A discharge dam (118) provides a predetermined average depth of molten bath material in the rotary kiln over its entire length. A blended ratio of comminuted materials injected through the pneumatic injection slinger feeder is adjusted and controlled in response to signals received from a radiative optical kiln bath temperature measurement system. Fluorides recovered from discharge gases exiting the secondary combustion chamber are recycled to the molten bath or pool of the rotary kiln, and glass frit residue from the ash quencher and cooler.
    • 一种用于处理废料的工业废物管理设施包括一个并流式燃气回转窑(10),用于在入口(12)的整个回转窑(10)的整个长度上容纳废液罐(15) 出口,用于从旋转窑的排出端接收熔融残渣的二氧化猝灭剂和冷却器(33),二次燃烧室(34)和用于引导来自旋转窑的排放气体的下降过渡室(32) 窑至二次燃烧室。 气动注射吊带(2,4)将废弃的铜罐进料并分配到回转窑的入口端。 排放坝(118)在其整个长度上在回转窑中提供熔融浴材料的预定平均深度。 响应于从辐射光窑浴温度测量系统接收到的信号,调节和控制通过气动注射抛光机进料器注入的粉碎材料的混合比例。 从排出的二次燃烧室排出的废气回收的氟化物被循环到回转窑的熔池或池中,以及来自灰烬器和冷却器的玻璃料残渣。

    • In a method of operating a glassmelting furnace (100) comprising a melting zone (11) and a refining zone (12), the melting zone is provided with pairs of opposed regenerators (41, 42). At least one gaseous stream or atomized fluid stream of fuel and at least one oxidant stream are injected e.g. through injectors (32, 33) and combusted into the refining zone above the molten glassmaking material to increase the average oxygen concentration in the atmosphere near said bath surface in said refining zone by 1 to 60 vol.%. The fuel and combustion air flow rates of each of said regenerator ports are adjusted to make the oxygen concentration in the flue gas exiting each of said regenerator ports located between the spring zone in the melting zone (11) and the refining zone (12) between 2 to 10 vol. %. Oxidized glass can be made and risk of crown corrosion is lessened.
    • 在操作包括熔化区(11)和精炼区(12)的玻璃熔化炉(100)的方法中,熔融区设置有成对的相对的再生器(41,42)。 燃料和至少一种氧化剂流的至少一种气流或雾化流体流被注入。 通过喷射器(32,33),并且燃烧到熔融玻璃制造材料上方的精炼区域中,以使所述精炼区域中所述浴表面附近的气氛中的平均氧浓度增加1至60体积%。 调节每个所述再生器端口的燃料和燃烧空气流速,以使烟道气中离开熔化区(11)和精炼区(12)的弹簧区之间的每个所述再生器端口处的氧气浓度在 2〜10体积 %。 可以制造氧化玻璃,并降低冠腐蚀的风险。
