FINE PARTICULATE FEED SYSTEM FOR FLUIDIZED BED FURNACE Abstract of the Invention A method and apparatus for feeding solids into the bed of a fluidized bed furnace (18). The feed solids are separated into a fine fraction and a coarse fraction. The coarse fraction is supplied to fluidized bed (16) in an in-bed pneumatic transport feed system or in an over-the-bed feed system. The fine fraction as well as fluidizing air are supplied to fines admission zone (24) wherein the fine fraction and fluidizing air are thoroughly mixed.
