Fluidized bed CVD arrangement
A means of scaling up fluidized bed chemical vapor deposition (FBCVD) production by using two or more small reactors instead of one large reactor. Each reactor has its own process gas delivery and exhaust lines. The furnace heating is designed such that each reactor has its own heater or there may be one large heater designed to keep the group of reactors at a constant temperature. This allows the shut down of a failed reactor without affecting production from other reactors.
1 . A fluidized bed chemical vapor deposition arrangement, comprising:
a. a furnace jacket;
b. at least two reactors positioned inside said furnace jacket, with each reactor having intake and exhaust lines; and
c. insulation placed in said furnace jacket around said reactors.
2 . The fluidized bed chemical vapor deposition arrangement of claim 1 , further comprising a heating element positioned around each reactor.
3 . The fluidized bed chemical vapor deposition arrangement of claim 1 , further comprising a single heating element positioned around all of the reactors.
4 . A means for scaling up a fluidized bed chemical vapor deposition process, comprising:
a. providing at least two reactors, with each reactor having separate process gas intake and exhaust lines; and
b. providing insulation around said reactors.
5 . The means of claim 4 , further comprising providing a separate heating element around each reactor.
6 . The means of claim 4 , further comprising providing a heating element around the reactors.
