Claims

[Scope of Claim for Utility Model Registration] 1. A large number of heat transfer tubes connecting the water supply inlet and water supply outlet 6 of the water supply chamber are arranged in the steam chamber, and the position is fixed by installing stay bolts fixed as appropriate. In the heat exchanger, a support plate is supported by a stay pipe, and the heat exchanger tube is supported by the support plate, and heat is exchanged between the water supply in the heat exchanger tube and the heated steam in the steam chamber. A heat exchanger characterized by having a large number of circulation holes for steam circulation. 2 The base of each stay pipe and stay bolt is 1. The heat exchanger according to claim 1, which is fixed to a tube plate that partitions a water supply room and a steam room. 3 There are 1 circulation hole and 4 at equal intervals in the circumferential direction of the stay pipe.
The heat exchanger according to claim 1 or 2, which is individually arranged in rows at predetermined intervals in the circumferential direction.
