A method and structure for stabilizing the depth of material in a first, highly turbulent fluidized bed of solids by discharging the flow of material from the bed over a weir into a second, relatively calm fluidized bed of solids, the weir defining a boundary between the two beds. The level of the second bed is maintained at substantially the same height as the top of the weir, and an outlet opening is provided in the second bed for discharging the solids therefrom in a constant, consistent manner in comparison to that of the first, turbulent bed.
