ABSTRACT:
A vibratory fluidized bed reactor vibrates a solid particle bed to fluidize the bed, and air or other gaseous stream is injected into the bed. The reactor can employ a rotationally-vibrated bowl or a linearly-vibrated pan. The vibratory motion keeps the particles evenly distributed and prevents blowholes from developing, leading to improved reaction. The vibratory motion also marches particles up a spiral groove in the circumferential wall of the bowl, e.g., to facilitate ash removal from the fuel bed, to recycle reactants or catalysts, to sequence reactants to subsequent stages, etc. In the case of the pan, vibratory motion marches the particles up an inclined plate.
