Gas firing heat treatment furnaces in which the protective gas must be sent for the purpose of non-decarburization and non-oxidation or carburizing are heated up indirectly by means of radiant tube burners, and regenerative burners are applied to the radiant tube combustion for High Performance Heat Treatment Furnace. As the result of regenerative burner application, the surface temperature distribution at the radiant tube is unified low in comparison with conventional radiant tube burners. This means that the radiant tube burner can be applied to high temperature heat treatment furnaces (e.g., brazing furnace, sintering furnace) in place of the electric heating. As regards the direct firing heat treatment furnace, the agitating effect of the regenerative burner combustion by the high-cycle switched operation and the high nozzle speed of the combustion air, can make the furnace compact and simple even at the lower furnace temperature. And the development of the gas-rich firing for the regenerative burner can extend the application range of High Performance Heat Treatment Furnace to the field of the non-oxidation treatment. (e.g., copper bright annealing etc.)
