It is sent to the duct 3. The combustion air A sent to the upper duct 3 is then mixed with fuel, thereby generating a flame toward the furnace. At this time, the exhaust valve 9 is closed (the closing operation is indicated by black solid notation in the figure). On the other hand, during the exhaust operation of the regenerative burner, the air supply valve 7 is closed and the exhaust valve 9 is opened, so that the exhaust gas B from the furnace flows into the vertical duct 2 through the upper duct 3.

Thereafter, when it is confirmed that the total amount of the spherical heat storage material 11 has fallen into the recovery container 18 by e.g. a predetermined time counted by a timer provided in the controller 19, a closing signal is sent to the lower gate 15. Thereafter, when it is confirmed that the lower gate 15 is closed by a sensor or the like that detects opening / closing of the lower gate 15, an open signal is sent from the controller 19 to the upper gate 14.
- the operation control of the valves 7 and 9 and the gates 14 and 15 is not performed by counting up by a timer or the like of the controller 19, but the operator confirms the situation visually and operates the controller 19 to operate the gates 14 and 15 and the valves 7 and 15. , 9 may be opened and closed. Even in that case, the controller 19 allows the control of the exchange operation in response to the air supply valve 7 being closed on condition that the exhaust valve 9 is closed. Therefore, the controller 19 prohibits the control of the exchange operation during the exhaust operation in which the exhaust valve 9 is opened.

- Reinforcing the lower gate plate 15a with the reinforcing ribs 15d or forming a heat-insulating bottom region C directly above the lower gate 15 ensures a reduction in the thickness of the lower gate plate 15a and the amount of heat-resistant material applied.
