PROBLEM TO BE SOLVED: To provide a combustion device capable of improving correct combustion by automatic processing on the basis of correct evaluation even in a large disturbance occurring environment such as a strong wind and a sudden gust of wind. SOLUTION: When the CO concentration exceeds 300 ppm, a fan rotating speed is increasingly corrected. The CO concentration D<SB>1</SB>of correction time Ta and the CO concentration D<SB>2</SB>of Tb just after its correction are stored. When the CO concentration D<SB>3</SB>of time Tc becoming a balance state after the correction is higher than 300 ppm, availability is determined on the setting of the correction in Ta to the UP side without taking the influence of disturbance into consideration. The fan rotating speed is decreasingly corrected only when D<SB>2</SB>becomes higher than D<SB>1</SB>, and when the D<SB>2</SB>becomes lower than D<SB>1</SB>, an UP correction is made again.
