  • Systems and methods for particle size determination and control in a fluidized bed reactor for use with thermally decomposable silicon-containing gas
    Patent number: 8849584
    Abstract: Systems and methods are provided for determining the size of particles within a fluidized bed reactor for use with thermally decomposable silicon-containing gas. The pressure of gas adjacent a gas inlet and adjacent a gas outlet of the reactor are measured with pressure sensors. An algorithm is applied to at least one of the pressure measurements to determine the size of particles within the reactor. The determined size of the particles can be used to control the operation of the reactor.
    Type: Grant
