A fluidized bed combustion apparatus, characterized in that a porous ceramic body is provided at the combustion gas outlet of the fluidized chamber across the outlet. (2) In a fluidized bed combustion apparatus that includes a gas distribution plate at the lower part of the fluidized chamber, fluidizes the fluidized medium on the gas distribution plate to form a fluidized bed, and burns the fuel in the fluidized bed. A porous ceramic body is provided across the exhaust port at the combustion gas discharge port, a coating material with high emissivity is applied to the inner wall surface of the fluidization chamber and the surface of the porous ceramic body facing the fluidization chamber, and the porous ceramic body is coated with a coating material having a high emissivity. 1. A fluidized bed combustion device characterized by having a porous ceramic body whose opening diameter is smaller than the diameter of the fluidized medium.
