PROBLEM TO BE SOLVED: To perform a combustion after taking prevention of exhaust gas from remaining by a method wherein when the timing for a fuel feeding motion is set by corresponding with the start of an air feeding in a heat regenerative burner device, valve members of a fuel feeding system are opened according to the pressure of the air feeding. SOLUTION: This device is constituted in such a manner that two heat regenerative burner devices 10, 10a are arranged in a furnace, and a combustion and a gas discharging are alternately performed by the two heat regenerative burner devices. In a fuel system 30, valve members 34, 34a are arranged, and for air feeding-discharging tubes 24, 24a of an air feeding system 20, pressure sensors S, S1 are respectively arranged. Then, when the heat regenerative burner device is switched from a gas discharging to an air feeding, the sensor detects the pressure of the air feeding, and under a state wherein the pressure has become a fixed value, a fuel is fed by opening the valve member. |
