  • Patent number: 9249973
    Abstract: There are formed inside a casing, a steam receiving chamber, a supply manifold chamber, a moisture separating chamber, a heating chamber adjacent to the steam receiving chamber in an axial direction and housing a heat exchanger tube group, and a collection manifold chamber communicating with the heating chamber and adjacent to an upper part of the steam heating chamber. The steam receiving chamber and the partition panel are separated by a transverse partition panel which extends in a vertical direction and through which an end of the heat exchanger tube group in the axial direction penetrates, and a shroud that shrouds the end of the heat exchanger tube group penetrating the transverse partition panel. The steam receiving and the collection manifold chambers are separated by a ceiling panel. A panel bonded to the ceiling panel, the transverse partition panel, and the shroud is provided in the steam receiving chamber.

  • Patent number: 8157898
    Abstract: A condenser having improved condensation performance is provided. The condenser includes a plurality of cooling pipes, being disposed in a chassis to which the steam is introduced, through the interior of which cooling water used for heat exchange with steam flows; an inner channel that extends in a top-bottom direction and that is surrounded by the plurality of cooling pipes; a plurality of pipe-supporting plates disposed at a distance from one another in a direction in which the plurality of cooling pipes extend to support the plurality of cooling pipes; and a water receiving portion disposed between the plurality of pipe-supporting plates and being inclined downward from one pipe-supporting plate to the other pipe-supporting plate.
