All-secondary air cooled industrial steam condenser

Abstract

A new design for large scale field erected industrial steam condensers in which all of the bundles are constructed as secondary bundles, in A-frame or V-Shape configuration, with tubes oriented 25-35 degrees from the vertical, steam fed from the bottom and condensate is collected from the bundles from the bottom using a combination/hybrid manifold that both delivers steam to the tubes and collects condensate from the tubes and which is constructed so that the condensate is prevented from returning down the steam delivery riser(s) and in which the cross-sectional dimensions of the tubes are 125 mm wide with a cross-section height of less than 10 mm with fins that are 9.25 mm in height, arranged at 9 to 12 fins per inch.
