    • The apparatus includes a radiation gathering device having a narrow acceptance angle and mounted in a multiburner boiler to sight substantially across the discharge end of the burner nozzle. Radiation collected by the gathering device is transmitted by a fiber optic path to a radiation detecting device. The manner in which the apparatus is constructed and mounted insures that the radiation detecting device will be responsive only to the radiation resulting from the associated burner and not influenced by radiation from other burners in the boiler installation, or radiation from the boiler itself.
    • 该装置包括具有窄的接受角度的辐射收集装置,并安装在多燃烧器锅炉中,基本上跨过燃烧器喷嘴的排放端。 由收集装置收集的辐射通过光纤路径传输到辐射检测装置。 装置的构造和安装方式确保辐射检测装置仅响应由相关联的燃烧器产生的辐射,并且不受来自锅炉设备中的其他燃烧器的辐射或来自锅炉本身的辐射的影响。

    • A process for the beneficiation of trona includes supplying a trona feedstream that is crushed and dried. The trona is then separated into a first size fraction and a second size fraction. Impurities are removed from the first size fraction using at least one magnetic separator. The magnetic separator includes a plurality of stages. Each stage includes a conveyer system comprising a first end, a second end, and a conveyer belt. Each stage also includes a magnetic roller disposed at the second end of the conveyer system and a splitter disposed adjacent the second end of the conveyer system for separating a fraction of magnetic impurities from the trona to create a beneficiated fraction. At least one conveyer belt is deionized. Airborne dust particles are removed from an area surrounding at least one conveyer system.
    • 选择天然碱的方法包括提供被粉碎和干燥的天然碱原料流。 然后将天然碱分离成第一尺寸部分和第二尺寸部分。 使用至少一个磁选机从第一尺寸部分除去杂质。 磁选机包括多个级。 每个阶段包括一个包括第一端,第二端和输送带的输送系统。 每个阶段还包括设置在输送系统的第二端处的磁性辊和邻近输送系统的第二端设置的分离器,用于将一部分磁性杂质与天然碱分离以产生精选馏分。 至少一个输送带是去离子的。 从至少一个输送系统周围的区域去除空气中的尘埃颗粒。
