となる。Next, the operation of this embodiment will be described. In the fluidized bed 3, due to the effect of stirring the fluidized medium (for example, silica sand), the heat transfer coefficient between the fluidized medium and the object to be treated is very good, and the temperature of the fluidized bed 3 tends to rise.
