Abstract
A fluidized bed of material retained in a vessel receives a high velocity gas stream through a venturi orifice and passage to assist in the agglomeration of ash particles. The particles form a semi-fixed bed within the passage upstream from the venturi orifice. The particular dimensions of the semi-fixed bed are dependent, in part, upon the orifice size of the venturi. An iris valve defining the orifice permits adjustment of the cross-sectional area of the orifice thereby controls the velocity of the gas stream through the venturi.
