Abstract
A tube plate of a heat exchanger includes a tube plate base material to which ends of a plurality of heat transfer tubes are fixed, a first backplate that covers a surface of the tube plate base material on a first tube chamber side, and a fastener that includes at least a shaft section and fixes the first backplate to the tube plate base material. The first backplate includes heat transfer tube insertion holes through which a plurality of heat transfer tubes are inserted, and an insertion hole through which the shaft section is loosely inserted. The first backplate is joined to an end section of a second partition wall on a first end side. The second partition wall, the first backplate, and the fastener are formed of a material having higher corrosion resistance than the tube plate base material.
