All-secondary air cooled industrial steam condenser

An all secondary bundle large scale field erected air cooled industrial steam condenser connected to an industrial steam producing facility, comprising:

• two bundles each comprising a plurality of finned flattened tubes fitted adjacent to one-another, each of said bundles oriented so that the longitudinal axis of said finned flattened tubes is positioned at an angle of 55°-65° from horizontal;
• a combined steam distribution-condensate collection manifold attached to a bottom of each of said bundles and running along a length of said bundles configured both to deliver steam to a bottom of said tubes and to collect condensate that forms in said tube from said steam as it cools;
• a non-condensable collection manifold attached to a top of each of said bundles and running along a length of said bundles parallel to said steam distribution manifold and configured to collect non-condensable gases from said steam.
