へ排出される。(Operation) Dehumidified air generated by the dehumidifier is introduced into the waste gas intake side of the exhaust heat recovery heat exchanger through the air supply temporary piping. Since the dehumidified air introduced into the waste gas intake side has a higher density and a heavier specific gravity than air containing moisture, it gradually accumulates from the lower layer to the upper layer of the exhaust heat recovery heat exchanger. When the dehumidified air is deposited from the lower layer to the upper layer of the heat recovery heat exchanger, the humid air that has occupied the inside of the heat recovery boiler is transferred to the waste gas discharge side of the heat recovery heat exchanger. It is discharged to the outside from the provided discharge port.

ｂ発錆を防止することがでさる。The filtered air introduced into the exhaust heat recovery heat exchanger absorbs moisture in the exhaust heat recovery heat exchanger, and the air that has absorbed moisture is guided to the dehumidifier again through the air suction temporary piping. In this way, the dehumidified air generated by the dehumidifier is introduced into the exhaust heat recovery heat exchanger and circulated, thereby dehumidifying and drying the JJI heat recovery heat exchanger. Therefore, it is possible to prevent rusting during long-term storage.
