description The present invention provides an economizer 70 including a plurality of cylindrical heat transfer tubes 71a-71d extending along a crossing direction crossing a flowing direction of combustion gas and disposed at a predetermined disposition interval P along the flowing direction, the combustion gas and fluid flowing in the plurality of heat transfer tubes performing heat exchange, and a swirl preventing section 75 disposed in contact with a downstream side outer circumferential surface 71Aa-71Ad in the flowing direction of each of the plurality of heat transfer tubes 71a-71d and configured to prevent a swirl of the combustion gas from occurring near the downstream side outer circumferential surface 71Aa-71Ad.
