PROBLEM TO BE SOLVED: To stabilize combustion and reduce the generation of NOx, in a heat storage type burner device. SOLUTION: The generation of NOx is restrained by a method wherein primary air is supplied from a primary air supplying pipe 5 around a fuel nozzle 4 while secondary air, low in the oxygen concentration thereof, is supplied through a heat storage body 7 to burn the fuel further. When a temperature in a furnace is low, the rate of the primary air is increased by a control unit 40 but the rate of secondary air is increased by the same unit 40 when the temperature in the furnace is high. |
