摘要： Fluidized bed reactor systems for producing high purity silicon-coated particles are disclosed. A vessel has an outer wall, an insulation layer inwardly of the outer wall, at least one heater positioned inwardly of the insulation layer, a removable concentric liner inwardly of the heater, a central inlet nozzle, a plurality of fluidization nozzles, at least one cooling gas nozzle, and at least one product outlet. The system may include a removable concentric sleeve inwardly of the liner. In particular systems the central inlet nozzle is configured to produce a primary gas vertical plume centrally in the reactor chamber to minimize silicon deposition on reactor surfaces.

摘要： Systems and methods for converting a powder to a solid mass are disclosed. A furnace is provided to melt the powder and deliver a stream of resulting molten material to a bed of beads on a vibratory conveyor. Cooling gas flows through nozzles positioned above and along the conveyor to cool the beads and liquid. The liquid solidifies and forms a solid mass, incorporating beads from the bed. The conveyor can be periodically stopped to produce a plurality of discrete solid masses. Masses and unincorporated beads fall into a collection container. Unincorporated beads pass through a screening device and are returned to the bed of beads. A make-up bead system adds beads to the bed as needed to maintain a suitable bed depth. In some embodiments, the powder and beads consist essentially of silicon, and the solid masses formed are suitable for preparing silicon ingots.
摘要翻译：公开了将粉末转化为固体物质的系统和方法。提供炉以熔化粉末并将所得熔融材料流输送到振动输送机上的珠粒床。冷却气流经位于输送机上方和下方的喷嘴，以冷却珠粒和液体。液体固化并形成固体块，从床中加入珠粒。输送机可以周期性地停止以产生多个离散的固体块。大量和非合并珠落在收集容器中。未掺入的珠粒通过筛选装置并返回到珠粒床。化妆珠系统根据需要将珠添加到床上以保持合适的床深度。在一些实施方案中，粉末和珠粒基本上由硅组成，并且形成的固体块适用于制备硅锭。
