<p>A fluidized-bed combustor combusts combustible material smoothly while smoothly removing any incombustible material from the fluidized-bed furnace without depositing the incombustible material therein. The fluidized-bed combustor (1) has a first diffuser plate (2), a second diffuser plate (3) each having a plurality of fluidizing gas supply holes, and an incombustible material discharge port (8) disposed between the first diffuser plate and the second diffuser plate. A portion of the fluidizing gas (15) is supplied from the incombustible material discharge port to generate an uninterrupted fluidized bed on the bottom of the fluidized-bed furnace. The first diffuser plate has a downwardly inclined surface directed toward the incombustible material discharge port, and the second diffuser plate has an upwardly inclined surface which is progressively higher away from the incombustible material discharge port. <IMAGE></p> |
