摘要： A method and device heat an object to be heated by a flame which is produced by supplying a fuel fluid and a combustion supporting gas to a burner as a heat, source. A temperature rising rate is increased by gradually increasing an oxygen concentration in the combustion supporting gas supplied to the burner and a device for heating an object to be heated including a burner for heating the object to be heated. A flow rate control unit controls a flow rate of a fuel fluid and a combustion supporting gas. A calculation unit transmits combustion information of the burner to the flow rate control unit, and the flow rate control unit increases a temperature rising rate of the object to be heated by increasing the oxygen concentration in the combustion supporting gas supplied to the burner.
