PROBLEM TO BE SOLVED: To provide a combustion controller for a stoker type incinerator, which achieves complete combustion with high combustion efficiency while suppressing generation of noxious components such as NOx and CO by a comparatively simple and inexpensive composition, by accurately carrying out combustion control in the incinerator and mixing ratio control of air-mixed recirculation gas returned to an incinerator side through a recirculation passage provided with a recirculation fan. SOLUTION: The combustion controller for the stoker type incinerator is provided with: an air flow rate adjusting means 30a for adjusting an air flow rate in an air passage 30; a temperature detecting means 35 (35a) for detecting a temperature of the air-mixed recirculation gas, and a combustion control means 60 to which a temperature detected value of the air-mixed recirculation gas from the temperature detecting means 35 (35a) is inputted, for calculating a passage area of the air flow rate adjusting means 36 such that the temperature of the air-mixed recirculation gas becomes a preset target temperature on the basis of the temperature detected value, and which controls the flow rate adjusting means 36 to a passage area integrated value.
