PROBLEM TO BE SOLVED: To provide an incinerator with reduced size, high incineration efficiency of an object and reduced total amount of exhaust gas discharged into the environment. SOLUTION: The incinerator comprises a primary combustion space 1 for burning the object to be burnt by receiving primary combustion gas, a secondary combustion space 2 communicating with the primary combustion space 1 for burning unburnt gas, a flue 3 for guiding the exhaust gas to a stack 7, a bag filter 4 provided at the flue 3, a first recirculation passage 31 for excessively introducing the primary combustion gas so that the exhaust gas at an exit of the secondary combustion space 2 has an oxygen concentration reaching a specified target value and sending some exhaust gas on an upstream side of the bag filter 4 of the flue 3 back to an upstream side of the secondary combustion space 2, and a first exhaust gas introducing nozzle 22 for agitating and mixing the unburnt gas of the secondary combustion space 2 with the recirculated exhaust gas.
