Abstract:
Segmented silicon carbide liners for use in a fluidized bed reactor for production of polysilicon-coated granulate material are disclosed, as well as methods of making and using the segmented silicon carbide liners. Non-contaminating bonding materials for joining silicon carbide segments also are disclosed. One or more of the silicon carbide segments may be constructed of reaction-bonded silicon carbide.
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.
