To provide a combustion furnace that can perform each process of dehydration/thermal decomposition, desulfurization, and decomposition of NO of organic waste by an optimum condition suitable for each process in a circulation type fluidized-bed combustion furnace for performing incineration processing of organic waste such as sewage sludge.SOLUTION: In order to perform each process of dehydration/thermal decomposition, desulfurization, and decomposition of NO of organic waste such as sewage sludge by an optimum condition, each process is divided into zones, and, preferably, a fluid medium heated to a high temperature of 850°C or higher required for the decomposition of NO is circulated through a heat exchanger before it is returned to the process of dehydration/thermal decomposition of organic waste so that heat can be used to the maximum.SELECTED DRAWING: Figure 1 【課題】 下水汚泥等の有機性廃棄物を焼却処理するための循環型流動層燃焼炉において、有機性廃棄物の乾燥・熱分解、脱硫、及びＮ２Ｏの分解のそれぞれの工程を、各々に適した最適な条件で行うことができる燃焼炉を提供する。【解決手段】 下水汚泥等の有機性廃棄物の「乾燥・熱分解」、「脱硫」及び「Ｎ２Ｏ分解」のそれぞれの工程を最適な条件で行わせるために、各工程をゾーン分けし、好ましくは、「Ｎ２Ｏ分解」工程に必要な８５０℃以上の高温にされた流動媒体を、有機性廃棄物の「乾燥・熱分解」工程に返送する前に、熱交換器に循環させることにより、熱を最大限利用することができる。【選択図】図１
