Zusammenfassung:PROBLEM TO BE SOLVED: To provide a fluidized bed sludge incinerator for preventing the generation of greenhouse gas, particularly, dinitrogen monoxide. SOLUTION: In the sludge incinerator, a fluidized bed with floating sand is formed by blowing air from the lower part of an incinerator body so that sludge is burnt in the fluidized bed and remaining combusible components in rising air are burnt in a free board. The temperature of a sand layer is controlled to a fixed temperature for suppressing the generation of dinitrogen monoxide, and a time for the sludge residing in the sand layer in the fluidized bed or a time for the sludge contacting the sand layer is elongated to increase components of the sludge to be burnt in the sand layer.
