IMPROVING OPERATION OF FLUIDIZED BED REACTORS BY OPTIMIZING TEMPERATURE GRADIENTS VIA PARTICLE SIZE DISTRIBUTION CONTROL

摘要

A method of improving the operation of polysilicon fluidized bed reactors is disclosed. The present disclosure is directed to the optimization of axial temperature gradients in gas-solid fluidized bed systems. Varying the width of the particle size distribution in the reactor alters the temperature gradient within the reactor, thereby providing a means of a better control of internal temperature profiles and hence better reactor performance.
