In one embodiment, a direct-contact steam condenser includes: a steam cooling chamber; a inflow part; a plurality of first spray nozzles; and a water reservoir part. The inflow part leads turbine exhaust gas containing steam and non-condensable gas in a substantially horizontal direction into the steam cooling chamber. The plurality of first spray nozzles are disposed in the steam cooling chamber to be connected to a plurality of spray pipes extending along the direction in which the turbine exhaust gas is led in, and spray cooling water to the turbine exhaust gas. The water reservoir part is disposed under the steam cooling chamber to store condensate water that is condensed from the steam by the spraying of the cooling water.

Direct-contact steam condenser

A condenser including a steam cooling tube bundle having a number of steam cooling tubes, an enclosure enclosing a central space formed at an inside of the steam cooling tube bundle, an air cooling tube bundle disposed in the enclosure and having a number of air cooling tubes, and a tube support plate supporting the steam cooling tube bundle. The steam cooling tube bundle includes upper and lower tube bundles. The enclosure includes a pair of enclosing bodies dividing the steam cooling tube bundle into two parts. Each of the enclosing bodies includes an upper enclosing plate having at least a sloping surface inclined downward to an outside from an inside of the enclosure and a bottom enclosing plate disposed downward of the upper enclosing plate. A flow opening is formed at a joined portion of upper and bottom enclosing plates to communicate the inner space and the outer space. A drain opening is formed at a joined portion of the bottom enclosing plate positioned at the inner space side and the tube support plate.

Condenser

In a device for separating the moisture contained in the cycling steam discharged out of a steam turbine and reheating the low-temperature steam is disclosed, a central chamber is defined between a pair of moisture separating structures and the bottoms of the central chamber, and the separating structures are closed by a closure structure. A steam chamber which is in communication with the central chamber is defined by a pair of side walls and the upper edge of each of the pair of side walls is loosely fitted into a guide groove defined by a pair of spaced guide plates which in turn are securely joined to the inner surface of the cylindrical shell.

Combined moisture separator and reheater

A reheater for a steam power plant generally comprises a tube plate, a header including a high-temperature chamber and a low-temperature chamber defined outwardly of the tube plate, and a number of heat-exchanger tubes bent into U-shapes, both ends of which are secured to the tube plate. The reheater further comprises nozzle members, each having a flange portion, inserted into the upstream ends of the heat-exchanger tubes, respectively, and a bellmouth plate having a number of holes, secured detachably to the tube plate such that the holes align with the nozzle members. The flange portions of the nozzle members are secured firmly between the bellmouth plate and the tube plate.
