PROBLEM TO BE SOLVED: To provide a combustion control method of a waste gasifying melting furnace wherein the overload combustion is not performed in either a free board of a gasification melting furnace and a secondary combustion furnace, and abnormal high temperature state does not occur in either the free board of the gasification melting furnace and the secondary combustion furnace. SOLUTION: In this combustion control method of the waste gasifying melting furnace comprising the gasification melting furnace 1 for gasifying the waste by thermal decomposition, and partially burning the thermally-decomposed gas, and the secondary combustion furnace 30 for secondarily burning the thermally-decomposed gas discharged from the gasification melting furnace, a temperature of a partial combustion area of the thermally-decomposed gas in the gasification melting furnace and a temperature in the secondary combustion furnace 30 are measured, and a flow rate of the air for partial combustion blown to the gasification melting furnace 1 and/or a flow rate of the air for secondary combustion blown to the secondary combustion furnace 30 are controlled to keep both of the temperatures of the gasification melting furnace 1 and the secondary combustion furnace 30 respectively in specific ranges.
