A fluidizing feed apparatus for supplying particulate material to a fluidized bed furnace. A housing defines a chamber which is divided by a perforated distribution plate into a gas plenum beneath the plate a particulate fluidizing plenum 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 of fluidized particulate material superadjacent the distribution plate and a splash zone thereabove. Transport conduits open into the splash zone at a selected distance above the surface of the discrete bed to receive particulate material and conveying gas therefrom for transport to the fluidized bed of the furnace.
