PROBLEM TO BE SOLVED: To enable complete stoppage of exhaust from a furnace in the stopping of all burner devices by controlling supply and exhaustion corresponding to the temperature of the burner devices in a supply/exhaustion system provided for the burner devices of a heat storage combustion burner apparatus. SOLUTION: Supply/exhaustion pipes 29... in a supply/exhaustion system 20 are connected separately to burner devices 10 and 10a arranged in a furnace 1 to perform a supply or an exhaustion with a four-way valve 24 and a fuel is supplied to perform a heating within the furnace. In the supply/exhaustion system 20, a valve is arranged for a supply pipeline 22 and an exhaust pipeline 26 to adjust the supply and the exhaustion according to the information on the temperature of the furnace. A valve 27 is subjected to the control of the exhaust quantity through a ratio setting device 33 aside from the control of the air supply quantity thereby allowing fully closing of the exhaust pipeline using a signal of an input circuit 38. |
