Zusammenfassung:PROBLEM TO BE SOLVED: To provide a combustion control system and a combustion control method for a furnace capable of keeping high combustion efficiency in accordance with a combustion state in the melting furnace. SOLUTION: This combustion control system in the furnace for heating a raw material including at least C by supplying a combustion gas including at least O2, includes an operation control device for operating a supply amount of O2on the basis of the concentration of a specific gas (exhaust gas) discharged from the furnace. The operation control device has the chemical reaction model for stoichiometrically specifying the relationship of a reaction ratio of the specific gas (in-furnace gas) and C in the raw material, the concentration of the exhaust gas, a temperature of the raw material and the concentration of the in-furnace gas.
