Air-cooled condenser system

An air-cooled condenser comprising:

• a longitudinal axis;
• a longitudinally-extending steam header configured for receiving steam from a source of steam;
• a pair of longitudinally-extending condensate headers positioned below the steam header and spaced laterally apart, the steam and condensate headers oriented parallel to each other;
• a pair of inclined tube bundles each comprising a plurality of tubes connected to an upper tubesheet and a lower tubesheet, the tube bundles disposed at an acute angle to each other;
• the upper tubesheets being hingedly and sealably connected together by a longitudinally-extending angled seal plate forming a fluid tight coupling therebetween, the seal plate comprising a resiliently flexible metal body operable to deform under thermal expansion or contraction;
• each tube bundle arranged between and in fluid communication with the steam header and a different one of the condensate headers at bottom;
• a fan arranged for blowing ambient cooling air upwards through the bundles;
• a fan platform configured to support and raise the fan above a support surface, the fan platform comprising a horizontal fan deck positioned below the tube bundles;
• wherein the tube bundles, steam header, and condensate headers form a self-supporting tube structure in which the tube bundles are not directly supported by any structural members above the fan deck.

An air-cooled condenser comprising:

• a longitudinal axis;
• a longitudinally-extending steam header configured for receiving steam from a source of steam;
• a pair of longitudinally-extending circular condensate headers positioned below the steam header and spaced laterally apart;
• a pair of inclined tube bundles each comprising a plurality of tubes connected to an upper tubesheet and a lower tubesheet, the tube bundles disposed at an acute angle to each other;
• each tube bundle extending between and fluidly coupled to the steam header at top and a different one of the condensate headers at bottom forming an A-shaped tube structure;
• a fan support frame supporting a fan below the tube bundles;
• the condensate headers each axially slideably supported by a saddle support fixedly attached to the fan support frame, the saddle supports each comprising an upwardly open arcuately curved support surface of semi-circular configuration which slideably engages the condensate headers;
• wherein the condensate headers are operable to expand or contract in length in a direction parallel to the longitudinal axis due to thermal expansion or contraction conditions.
