Plural composite panels are aligned in multiple horizontal rows. Each composite panel includes a titanium panel (anode), an electrical insulating member and a stainless-steel band member. The titanium panels (also, stainless-steel band members) of horizontally adjacent panels overlap each other to be in face-to-face contact. The stainless-steel band members are horizontally connected at different levels to form long negative electrodes (cathode) extending in seawater-flowing direction in an inlet channel. Each stainless-steel band member is exposed to seawater through a gap between vertically adjacent composite panels.

System for preventing adhesion of marine organisms

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

A feed water heater has a longitudinally cylindrical body comprising a cylindrical shell portion constituting a main body portion of a feed water heater and a water box-shaped chamber operatively connected to the cylindrical shell portion and partitioned by a tubesheet. In the cylindrical shell portion, a heat exchanger tube bank is arranged and supported by a plurality of support plates, a drain cooling section is disposed in association with the heat exchanger tube bank for carrying out a heat recovery of a drain generated in the heat exchanger tube bank, a dilution condensing chamber is provided for the heat exchanger tube bank and adapted to excessively flow the steam into the heat exchanger tube bank, and a non-condensable gas chamber is provided for the heat exchanger tube bank. The drain cooling section, the dilution condensing chamber and the non-condensable gas chamber are arranged axially in this order in the cylindrical shell from the tube sheet.

Feed water heater

The present invention provides a condenser which is free from pressure loss of air stream due to an air exhaust pipe and loss of thermal energy, and which is compact. In the condenser according to the present invention, deflector plates 27b are disposed in a vertically central part of a first cooling pipe bundle having a number of cooling pipes extended in parallelism with each other and in a first horizontal direction of the condenser. The deflector plates 27b are diverged downward to both sides and provide a roof of air cooling chambers 24a, 24b. Second cooling pipe bundles 25a, 25b are disposed respectively in the air cooling chambers 24a, 24b. An air exhaust inner pipe 29 is extended upward in the first cooling pipe bundle 20 in communication with upper spaces 34a, 34b in the air cooling chambers 24a, 24b.
