PROBLEM TO BE SOLVED: To provide a combustion method by a fluidized bed boiler can positively reduce both of NOx and SOx in exhaust gas without providing a new facility such as desulfurization facility or a denitrization catalyst and enlarge a facility in carrying out combustion by mixing coal rich with volatile matter. SOLUTION: In combustion by mixing the coal rich with volatile matter in a combustion furnace of the fluidized bed boiler blowing fluidizing air and combustion air into plural places and increasing a volatile matter portion of the coal after coal blending 5 mass% or more, moisture is added to at least one of the fluidizing air or the combustion air blown into the combustion furnace 2 of the fluidized bed boiler 1, or moisture is input into the combustion 2 to carry out desulfurization, and the NOx and the SOx in the exhaust gas are reduced.
