Abstract: 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.

Abstract: Embodiments of a probe assembly for a fluid bed reactor are disclosed. The probe assembly includes a fluid bed reactor (FBR) member, and a pressure tap comprising a wall defining a passageway within which the FBR member is located. Exemplary FBR members include, but are not limited to, a thermocouple, a seed pipe, a particle sampling line, a gas sampling line, a gas feed line, a heater, a second pressure tap, or a combination thereof. Disclosed embodiments of the probe assembly reduce or eliminate the need for support rods and rings within the fluid bed reactor, reduce component fouling within the reactor, and/or reduce product contamination.
