Air-cooled condenser system and method for setting up such a condenser plant

Abstract

An air-cooled condenser system ( 1 ) comprises a platform ( 2 ) carrying heat exchanger elements ( 4 ), steam distribution lines ( 6 ), and fans ( 5 ). The platform ( 2 ) is arranged on pillars ( 3 ), which previously are introduced into the soil beneath the platform. The platform ( 2 ) is mounted close to the ground, wherein the intake chamber ( 21 ) required beneath the platform ( 2 ) is formed by removing soil beneath the platform ( 2 ). In this way, the platform ( 2 ) can be mounted at low height and with little effort.

1 - 16 . (canceled) 
     
     
         17 . An air-cooled condenser system, comprising:
 a platform having heat exchanger elements, steam distribution lines and fans, pillars supporting the platform, and   an intake chamber formed underneath the platform at least partially by an excavation in the ground.   
     
     
         18 . The condenser system of  claim 17 , wherein the excavation has sloped edges. 
     
     
         19 . The condenser system of  claim 18 , wherein the sloped edges have a slope angle of approximately 15° to approximately 45°. 
     
     
         20 . The condenser system of  claim 18 , wherein the sloped edges are arranged in regions next to the platform. 
     
     
         21 . The condenser system of  claim 17 , wherein the intake chamber comprises a horizontal floor area bounded by the sloped edges and wherein the horizontal floor area is greater than the horizontal base area of the platform. 
     
     
         22 . The condenser system of  claim 17 , wherein a mound with sloped embankments is arranged on a floor of the excavation underneath the platform. 
     
     
         23 . The condenser system of  claim 22 , wherein a height of the mound is between 30% and 70% of a distance between a surface of the floor of the excavation and a bottom edge of the platform. 
     
     
         24 . The condenser system of  claim 17 , further comprising a wall arranged at an edge of the excavation, with a crest of the wall projecting above a height of the platform above ground level. 
     
     
         25 . The condenser system of  claim 24 , wherein the crest is located in a horizontal plane which intersects top edge of the heat exchanger elements. 
     
     
         26 . The condenser system of  claim 24 , wherein the wall is formed from soil excavated from the excavation. 
     
     
         27 . A method for constructing an air-cooled condenser system having a platform supported on pillars, with fans, heat exchanger elements and steam distribution lines installed on the platform, the method comprising the steps of:
 introducing the pillars into the ground,   mounting the platform on the pillars, and   forming an excavation underneath the platform so as to form or to enlarge an intake chamber underneath the platform.   
     
     
         28 . The method of  claim 27 , wherein the platform is mounted on the pillars at ground level and the intake chamber is formed in its entirety by removing soil from underneath the platform. 
     
     
         29 . The method of  claim 27 , wherein the platform is mounted on the pillars at a height above ground level, wherein the height is smaller than a vertical height of the intake chamber after completion, wherein the vertical height of the intake chamber is increased by removing soil from underneath the platform. 
     
     
         30 . The method of  claim 27 , further comprising the step of forming a mound with a sloped embankment on a floor of the excavation underneath the platform. 
     
     
         31 . The method of  claim 27 , further comprising the step of constructing a wall at an edge of the excavation. 
     
     
         32 . The method of  claim 31 , wherein the wall is constructed from soil removed from the excavation.
