Abstract

A stacked panel tube bundle for an air cooled steam condenser having two sets of condensing tubes, one set arranged above the other, the first (lower) set of tubes in direct fluid communication with a combined steam delivery/condensate collection manifold at a bottom end and in indirect fluid communication with a non-condensable collection manifold via an L-shaped extension member; the second (upper) set of tubes in direct fluid communication with the non-condensable collection manifold at the top, and in indirect fluid communication with the combined steam delivery/condensate collection manifold via an L-shaped extension member.

First claim

The invention claimed is:

1. A heat exchange tube bundle comprising:
a first set of flat finned tubes arranged in a single row parallel to one-another;
a second set of flat finned tubes arranged in a single row parallel to one-another, above said first set of flat finned tubes;
a first conduit, having a first conduit vertical segment and a first conduit horizontal segment, said first conduit vertical segment and said first conduit horizontal segment in fluid communication with one-another; a bottom of said first conduit vertical segment in fluid communication with a bottom manifold; a top of said first conduit horizontal segment in fluid communication with bottoms of said second set of flat finned tubes; and
a second conduit, having a second conduit horizontal segment and a second conduit vertical segment, said second conduit horizontal segment and said second conduit vertical segment in fluid communication with one-another; a bottom of said second conduit horizontal segment in fluid communication with tops of said first set of flat finned tubes; a top of said second conduit vertical segment in fluid communication with a top manifold;
said second set of flat finned tubes separated from said first set of flat finned tubes by said first conduit horizontal segment and said second conduit horizontal segment; said first conduit horizontal segment located above said second conduit horizontal segment.

2. A heat exchange tube bundle according to claim 1 , wherein said heat exchange tube bundle is a first stage condenser, said bottom manifold is a combined steam delivery/condensate collection manifold, and said top manifold is an inter-condenser manifold.

3. A heat exchange tube bundle according to claim 1 , wherein said heat exchange tube bundle is a second stage condenser, said bottom manifold is a combined condensate/non-condensable gas collection manifold, and said top manifold is an inter-condenser manifold.

4. An air cooled steam condenser comprising heat exchange panels, each said heat exchange panels comprising one or more heat exchange tube bundles according to claim 1 .

5. An air cooled steam condenser according to claim 4 comprising pairs of said heat exchange panels arranged in A-frames.

6. An air cooled steam condenser according to claim 4 comprising pairs of said heat exchange panels arranged in V-shapes.

7. A large scale field erected air cooled industrial steam condenser connected to an industrial steam producing facility, comprising:
a single or plurality of condenser streets, each condenser street comprising a row of condenser modules, each condenser module comprising a plenum section having a single fan or multiple fans drawing air through a plurality of heat exchanger panels supported in a heat exchanger section, and each heat exchanger panel having a longitudinal axis and a transverse axis perpendicular to its longitudinal axis, each heat exchanger panel comprising at least one heat exchange tube bundle according to claim 1 .

8. A large scale field erected air cooled industrial steam condenser according to claim 7 , said combined steam delivery/condensate collection manifold having a single steam inlet.

9. A large scale field erected air cooled industrial steam condenser according to claim 7 , wherein each said condenser module street comprising a steam distribution manifold below said heat exchanger section and arranged along an axis that is perpendicular to a longitudinal axis of said heat exchanger panels at a midpoint of said heat exchanger panels and extending a length of said condenser module street beneath a plurality of heat exchanger panels, said steam distribution manifold comprising plurality of connections adapted to connect to each said single steam inlet.
