Abstract

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.

Claims5

Dependent claims

A condenser, comprising:

a steam cooling tube bundle having a number of steam cooling tubes disposed in parallel with each other and extending horizontally;
an enclosure enclosing a central space formed at a center portion in a vertical direction at an inside of said steam cooling tube bundle;
an air cooling tube bundle disposed in said enclosure and having a number of air cooling tubes disposed in parallel with each other and extending along an extending direction of said steam cooling tube bundle;
and
a tube support plate supporting said steam cooling tube bundle;
said steam cooling tube bundle including an upper tube bundle positioned upward of said central space and a lower tube bundle positioned downward of said central space;
said enclosure including a pair of enclosing bodies disposed separately each other and symmetrically with respect to a vertical surface dividing said steam cooling tube bundle into two parts;
each of said enclosing bodies including an upper enclosing plate having at least a sloping surface inclined downward to an outside from an inside of said enclosure and a bottom enclosing plate disposed downward of said upper enclosing plate;
said bottom enclosing plate including an outermost end extending outside from an outermost end of said upper enclosing plate, and further including an outer dam part erected at said outermost end of said bottom enclosing plate;
said bottom enclosing plate including an innermost end extending inside from an innermost end of said upper enclosing plate, and further including an inner dam part erected at said innermost end of said bottom enclosing plate;
a lower end portion of said outermost end of said upper enclosing plate being joined to an upper surface of said bottom enclosing plate, thereby dividing an upper space of said upper enclosing plate into an inner space and an outer space;
a flow opening being formed at a joined portion of said upper enclosing plate and said bottom enclosing plate to communicate said inner space and said outer space;
and
a drain opening being formed at a joined portion of said bottom enclosing plate positioned at said inner space side and said tube support plate.
