<P>PROBLEM TO BE SOLVED: To provide a fluidized incinerator system allowing improvement of heat efficiency of the whole system including an air preheater. <P>SOLUTION: In this fluidized incinerator system, sludge is brought into a cake state and is put into an incinerator body, and the sludge is incinerated in a fluidized bed part and a free board part inside the incinerator body. Exhaust gas including incineration ash of the sludge discharged from the free board part is cooled by the air preheater, is cooled by a white smoke preventing heat exchanger, and is introduced to an exhaust gas processor. Combustion air heated by the air preheater is supplied to a fluidized incinerator. An exit temperature of the combustion air preheated by the air preheater is preheated to about 700°C, a temperature of the fluidized bed part is maintained at about 800°C-about 850°C, and a temperature of the exhaust gas discharged from the free board part is controlled to about 850°C. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
