PROBLEM TO BE SOLVED: To provide a heat exchanger capable of discharging a noncondensing gas such as air flowing into a heat exchange container with steam, to the external.SOLUTION: A heat exchanger includes a cylindrical member 41 communicated with a heat exchange container at an inlet end 41a, and opened to atmospheric air at an outlet end 41b to discharge a gas. The heat exchanger includes a fixed base 51 having an opening 52, a rotatable movable base 61 disposed in a manner of being overlapped to the fixed base 51 so that an opening 62 is lapped over the opening 52 of the fixed base 51, blades 64 disposed on a side face of the movable base 61, and making torque in a specific direction act on the movable base 61 by action of fluid force of a gas, and a weight 65 (resistance force application mechanism) disposed on a position separating from a center of rotation on the side face of the movable base 61. A lapping area of the openings 52, 62 is increased in accordance with rotation of the movable base 61, and a plurality of passage formation members 43, 44, 45, 46 are arranged in an axial direction of the cylindrical member 41 so that phases of lapping parts of the opening portions 52, 62 are shifted from each other, to form a labyrinth passage 47.SELECTED DRAWING: Figure 2 |
