Abstract
There is disclosed a new and improved multi-row steam condensing bundle for use in air-cooled vacuum steam condensers employed in power plant applications and the like. Specific freeze protection design is directed to the first row of tubes in the bundle by employing blow-through steam. The excess steam that is not condensed in the first row is introduced into a second pass reflux row of tubes located in the protected warm air region of the bundle. All other tube rows in the bundle are of single pass design with divided rear headers except when the last two rows are configured in a similar two-pass arrangement that protects the exposed top tube row of the bundle from cold wind gusts. It is a mixed flow bundle design because some of the tube rows have counterflow steam and condensate while others have parallel flow.
