Abstract
Systems and methods are provided for determining the size of particles within a fluidized bed reactor. 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. A dosing system and method is provided for measuring defined volumes of particles for transport to the reactor.
