Claims

[Scope of utility model registration request]

In a fluidized bed combustion apparatus in which char exiting a fluidized bed combustion furnace is supplied to the fluidized combustion furnace again through a cyclone and an external heat exchanger, a fluidizing gas such as exhaust gas or high temperature air is placed at the bottom of the external heat exchanger. A fluidized bed combustion device characterized by being provided with a dispersion plate that spouts out.
