A method, apparatus and system for recycling ash fines emanating from fluidized bed reactor to ash classifier thereof. The fluidized bed reactor comprises a reaction vessel, a conical gas distribution grid positioned therein which defines the bottom surface of the fluidized bed, a first venturi connected to the bottom of the gas distribution grid, and a classifier connected to the bottom of the first venture. The method comprises separating the fine ash particles from the exit gas stream, and using a transport gas stream to deliver the fine ash particles collected into the classifier wherein the transport gas is used as all or part of classifier gas. |
