Since the combustion body 14 is closed and maintains sufficient pressure, the high-temperature combustion products are ejected at a high speed, thereby enhancing convective heat transfer, promoting air circulation in the furnace, and evenly recording the temperature. If the excess amount of primary and secondary air is increased, the temperature of the outlet gas can also be adjusted to make it close to the heating temperature of the workpiece, preventing the workpiece from overburning and ensuring the heating quality.
