ABSTRACT:
A fluidizing feed apparatus (20) for supplying particulate material to a fluidized bed furnace (12). A housing (22) defines a chamber which is divided by a perforated distribution plate (24) into a gas plenum (26) beneath the plate and a particulate fluidizing plenum (28) above the plate. Conveying gas is fed under pressure to the gas plenum to pass upwardly therefrom through the perforated distribution plate. The upwardly directed conveying gas fluidizes the particulate material so as to establish a discrete bed (60) of fluidized particulate material superadjacent the distribution plate (24) and a splash zone (70) thereabove. Transport conduits (14) open into the splash zone (70) at a selected distance above the surface (65) of the discrete bed (60) to receive particulate material and conveying gas therefrom for transport to the fluidized bed (16) of the furnace (12).
