| description | The present invention relates to a gas distribution unit for a fluidized bed reactor system, a fluidized bed reactor system having the gas distribution unit, and a method for preparing granular polysilicon using the fluidized bed reactor system. The gas distribution unit for a fluidized bed reactor system according to the present invention enables gas flow rate control and gas composition control for each zone within the plenum chamber. In addition, a fluidized bed reactor system having the gas distribution unit enables shape control of a fluidized bed (in particular, transition between a bubbling fluidized bed and a spout fluidized bed). The method for preparing granular polysilicon using the fluidized bed reactor system not only simultaneously improves process stability and productivity, but also enables more flexible handling in the event of an abnormal situation. |
