A method of firing a burner into a furnace process chamber supplies the burner with fuel and combustion air at a ratio that provides a level of excess air. The method includes the steps of reducing the flow rate of combustion air, and maintaining the level of excess air when the flow rate of combustion air is being reduced. Other steps include withdrawing exhaust gas from the process chamber, and supplying the burner with the exhaust gas at an increasing flow rate when the flow rate of combustion air is being reduced.
