PROBLEM TO BE SOLVED: To supply water to a boiler while continuously or intermittently discharge a part of the water of a boiler in order to prevent the concentration of the supplied water to the boiler made alkaline by the addition of a chemical agent to once store the discharged water in water tank and to neutralize the stored water efficiently at a low cost using carbon dioxide in the combustion exhaust gas of the boiler as a neutralizing agent when the stored water is neutralized to be discharged. SOLUTION: In a method for supplying water to the boiler 1 while continuously or intermittently discharging a part of the water of a boiler in order to prevent the concentration of the supplied water to the boiler made alkaline by the addition of a chemical agent to once store the discharged water in a water tank 3 and neutralizing the stored water to discharge the same, the combustion exhaust gas of the boiler is injected in the water tank 3 by a blower 5 to perform at least a part of neutralization by carbon dioxide in the gas.
