Abstract

To provide a condenser including a housing formed in a hollow shape and provided with a steam inlet and a condensate outlet, inlet water chambers and outlet water chambers provided at respective ends of the housing, a large number of heat-transfer tubes that connect the inlet water chambers and the outlet water chambers to each other inside the housing, in which cooling water flows, and intake pipes and drainpipes respectively coupled to the inlet water chambers and outlet water chambers via expansion joints.

First claim

1 . A condenser comprising:
a housing formed in a hollow shape and provided with an inlet of steam and an outlet of condensate; an inlet water chamber and an outlet water chamber provided at respective ends of the housing; a large number of heat-transfer tubes that connect the inlet water chamber and the outlet water chamber to each other inside the housing, in which a cooling medium flows; intake pipes and drainpipes respectively coupled to the inlet water chamber and the outlet water chamber via an expansion joint; a damping member that damps displacement of the inlet water chamber and the outlet water chamber; and a restoration member that restores positions of the inlet water chamber and the outlet water chamber, wherein the housing, the intake pipes, and the drainpipes are supported on an installation surface, a support structure having predetermined stiffness set in advance is placed on the installation surface, and the damping member and the restoration member are interposed respectively between the inlet water chamber and the support structure, and between the outlet water chamber and the support structure.

2 . (canceled)

3 . The condenser according to claim 2 , wherein a concrete structure is installed on the installation surface, and the housing and the support structure are supported by the concrete structure.

4 . The condenser according to claim 2 , wherein the support structure is placed so as to surround the inlet water chamber and the outlet water chamber.

5 . The condenser according to claim 1 , wherein the inlet water chamber and the outlet water chamber are provided in a plurality of sets with respect to the one housing, adjacent to ends of the housing, and the damping member and the restoration member are interposed between the inlet water chamber and the outlet water chamber adjacent to each other.

6 . The condenser according to claim 1 , wherein the damping member and the restoration member are interposed between the inlet water chamber and the outlet water chamber in the respective housings adjacent to each other.

7 . The condenser according to claim 1 , wherein end portions of the damping member and the restoration member are rotatably supported.

8 . The condenser according to claim 1 , wherein the inlet water chamber and the outlet water chamber are formed to be long along a vertical direction, an inlet nozzle and an outlet nozzle provided at a lower part thereof are coupled to an intake pipe and a drainpipe via the expansion joint, and end portions of the damping member and the restoration member are coupled to the vicinity of the expansion joint in the inlet water chamber and the outlet water chamber.
