ABSTRACT:
A fluidized bed reactor in which a grate is disposed in a housing for receiving a single bed of particulate material. The interior of the housing below the grate is divided into a plurality of zones and air is selectively passed through portions of the grate to fluidize corresponding portions of the bed above the zones. A plurality of pipes are provided in the bed for receiving excess particulate material accumulating in various portions of the bed and for blowing air into said latter portion, to reduce the build-up of particulate material in the bed.
