PURPOSE:To prevent titanous condenser pipes from being broken, and to prolong their lives, by removing a fear that a baffle plate may hit the condenser pipes, by disposing rod materials of which section modulus is large in the vicinity of the baffle plate, in a condenser in which a baffle plate is disposed in a cluster of titanous condenser pipes, so as not to contact with condenser pipes. CONSTITUTION:Instead of condenser pipes, among titanous condenser pipes 4, in the vicinity of a baffle plate 11b, that is to say, in the neighborhood of the baffle plate 11b, solid bars 12, 12..., as an example of rod materials, are disposed, being supported by partitioning plates 7 and supporting plates 10. The steam discharged from a turbine collides against the condenser pipes 4 nearly in the sonic speed, and each condenser pipe 4 is deflected by this steam pressure. But collision will not occur among the condenser pipes, because distances among the partitioning plates 10 are determined so that the condenser pipes 4 do not contact with each other. Besides, the disposed distance between the condenser pipe 4 and the solid bar 12 is as same as the distance among the condenser pipes 4, and the solid bar 12 has larger section modulus than that of condenser pipe 4, its rigidity is large, and is harder to be deflected than the condenser pipe 4. Accordingly, condenser pipes 4 and solid bars 12 will not be contacted with each other, and repeated impact load acted on the condenser pipes 4 can be prevented. |
