As shown in No. 259, etc., it is constituted by means for concentrating carbon dioxide gas in the combustion gas. The carbon dioxide gas is supplied, for example, by combustion in a gas water heater, and the combustion gas containing carbon dioxide gas is supplied to the carbon dioxide gas concentrator by a blower. Then, in a temperature swing type carbon dioxide gas concentrator using an adsorbent, the combustion gas is cooled and dehumidified by a heat exchanger in the preceding stage of the adsorption tower, and near complete dehumidification is performed in the water vapor adsorption tower.

が必要であった。However, since the conventional fin-and-tube heat exchanger flows the combustion gas perpendicularly to the long side direction of the plate fins, the product area of the long side direction and the number of fins direction becomes large, and the combustion is increased. A large header was required to evenly contact the gas on each plate fin. Therefore, a large space is required, and the carbon dioxide concentrator has become large. Moreover, in the conventional fin-and-tube heat exchanger, the heat exchange of the combustion gas and the cooling water is orthogonal, so the heat exchange efficiency is low and a large heat transfer area is required to cool the combustion gas to the target temperature. Met.
