Abstract
A fluidized bed reactor including a reaction vessel, which contains a conical gas distribution grid, a first venturi connected to the bottom of the gas distribution grid, and a classifier connected to the bottom of the first venturi; a fine ash particle collection system; and a fine ash particle conveyor system. Also disclosed is a method for recycling fine ash particles, the method including separating the fine ash particles from an exit gas stream, and using a transport gas to deliver the fine ash particles into the classifier.
