Abstract

The present invention relates to a fluidized bed reactor for preparing particulate polycrystalline silicon, and a preparation method of polycrystalline silicon using the same. More specifically, the present invention provides a fluidized bed reactor for preparing particulate polycrystalline silicon in which a flowing gas is injected at a lower portion of a chamber and reaction is carried out at an upper portion of the chamber, and a preparation method of polycrystalline silicon using the same, wherein the fluidized bed reactor for preparing particulate polycrystalline silicon comprises: a closed chamber; a tubular heating device placed inside the chamber; a first supply pipe for supplying the flowing gas into the heating device, formed at the lower portion of the chamber; and a venturi for increasing the velocity of the flowing gas inside the heating device.
