Abstract: A fluidized-bed reactor is suitable for uniformly oxidizing, i.e. combusting or gasifying, solid material containing combustible material and incombustible material, and for stably recovering thermal energy from the oxidized combustible material while smoothly discharging the incombustible material. The fluidized-bed reactor comprises a plurality of fluidizing gas diffusion devices disposed at a bottom of a fluidized-bed furnace for imparting different fluidizing speeds to the fluidized medium in a fluidized bed in the fluidized-bed furnace to form an upward flow of the fluidized medium in a fluidizing region with a substantially high fluidizing speed of the fluidized medium and a descending flow of the fluidized medium in a fluidizing region with a substantially low fluidizing speed of the fluidized medium. A plate-like thermal energy recovery device is disposed in the fluidizing region with the substantially low fluidizing speed of the fluidized medium and has a heat recovery surface extending vertically.
