A condenser includes heat transfer pipe groups, a main body and an intermediate body. The intermediate body has an inlet that opens in a horizontal direction, and an outlet that opens downward. The main body has an inlet that opens upward and is connected to the intermediate body outlet. The heat transfer pipe groups are arranged in the horizontal direction and disposed in the main body. A near-side outlet edge is an edge of the intermediate body outlet on a side near the intermediate body inlet in the horizontal direction and a far-side outlet edge is an edge of the intermediate body outlet on a side far from the intermediate body inlet. At least one part of the main body is located below an imaginary line that connects the near-side and far-side outlet edges and at least one part of the main body is located above the imaginary line.

A U-tube heat exchanger wherein a tube support plate divides the interior of a tube-exterior fluid chamber into a curved-tube chamber on a second end side including curved-tube sections of the U-tubes, and a chamber on a first end side. A second partition wall divides the interior of the chamber on the first end side inside the tube-exterior fluid chamber into a first straight-tube chamber including inlet-side straight-tube sections of the U-tubes, and a second straight-tube chamber including outlet-side straight-tube sections of the U-tubes. An opening penetrating from the first straight-tube chamber into the second straight-tube chamber is formed in the second partition wall. First passage holes, which penetrate from the first straight-tube chamber into the curved-tube chamber, and second passage holes, which penetrate from the second straight-tube chamber into the curved-tube chamber, are formed in the tube support plate.

U-tube heat exchanger

A condenser includes a container into which steam is to flow, cooling pipes which are positioned inside the container and configured to cool the steam so as to form condensed water, at least one extraction pipe for extracting air included inside the container, at least one extraction hole which is defined in the extraction pipe and through which an interior of the at least one extraction pipe and an interior of the container communicate with each other, and a cylindrical cover which is configured with a gap spaced from the at least one extraction pipe and covers the at least one extraction hole so as to regulate an inflow of the condensed water into the at least one extraction hole. A plurality of the extraction holes are formed around the extraction pipe, and the cylindrical cover is radially outside the at least one extraction pipe with the gap spaced therebetween.

Condenser and turbine equipment

This fuel-preheating device is provided with the following: a cooling-steam line that supplies steam, for the purposes of cooling, to a hot part of a gas turbine, namely a combustion liner of a combustor; a superheated-steam line through which superheated steam that is steam having passed through the combustion liner of the combustor flows; and a preheater that receives the superheated steam from the superheated-steam line and preheats fuel to be supplied to the combustor by exchanging heat between the superheated steam and said fuel.
