The Effect of Secondary Distributor on Hydrodynamic of Fluidized Bed Reactor

In the fluidized bed reactors, the gas-phase flow turbulent flow increases, causing clotting phenomenon and is away from the bubble flow regime. It also causing a rapid flow regimes and air transport and will be reduced performance of fluidized bed reactor.To solve these problems, in this research, in addition of floor distributor, a secondary distributor has been used for gas phase distribution.In the experiments the effect of gas flow secondary distributor on bubble diameter has been studied. Experimental results showed that bubble diameter was decreased 50 percent because of using secondary distributor. So it will be improve and increasing contact of gas –solid.
