PURPOSE: The combustion operation and the heat storage operation are switched, the change of the inner pressure of the heat storage burn-out thermal process furnace or the sudden incomplete combustion is controlled. CONSTITUTION: A combustion control method for regenerative-combustion heat treat furnace(10) comprises the following steps. Supplies an amount of the fuel gas to fuel gas supply pipes(28a,28b) of regenerative burners(20a,20b) in the heat storage burn-out thermal process the fuel gas supply device. When the combustion action and the regenerating motion are switched in a pair of regenerative burners, in the regenerative burner performing combustion action, the amount of the combustion air and the fuel gas provided through the fuel gas supply pipe and an air supply pipe(24a) diminishes. In the regenerative burner performing regenerating motion, the fuel gas and combustion air are provided through the fuel gas supply pipe and an air supply pipe(24b). Disclosed is the combustion of the regenerative burner performing regenerating motion. |
