PROBLEM TO BE SOLVED: To provide a combined fluidized bed incinerator, in which it is unnecessary to crush a big object to be combusted, and it is also unnecessary to install a pipe in a fluidized bed even for a high-calorie object, a low-calorie object to be combusted and slurry-like or sludgy objects can be treated at the same time by combustion, and the efficiency of the incineration operation and convenience are improved. SOLUTION: A high-calorie object to be combusted, which is charged from a second charging port 14 is combusted on a stoker 21 to become cinder, when a big lump of an object to be combusted is partially combusted on the stoker 21, it becomes brittle to cause a self crushing into small lumps. The combusted objects fall into a fluidized bed incinerator 1, and mixed with slurry-like or sludgy or low-calorie objects charged directly into a fluidized bed 10 from a charging port 13, and they are perfectly combusted.
