<p>TUBE BUNDLE There is disclosed apparatus for condensing steam, or other vapors containing non-condensibles such as air, which includes bundles each made up of a single row of parallel, side-by-side and spaced-apart tubes over which air is passed in a direction transverse to the row. Each tube has substantially parallel side walls which are generally parallel to the side walls of adjacent tubes, with the side walls being substantially longer in the direction of air flow than the width of the tube.</p> |
