The return pipe 5 extends through the heating furnace 1 and has multiple exhaust holes 19. The fan 3 draws hot air from the heating furnace 1 into the regenerator 2 through the exhaust pipe 9, thereby heating the ceramic plate 15 to store heat. After firing, the fan 3 discharges the stored hot air into the heating furnace 1 through the return pipe 5. The air in the heating furnace 1 can enter the regenerator 2 through the exhaust pipe 9 for circulation, thereby completing the preheating of the heating furnace 1.
