Definitions

  • This application relates generally to a steam condensation system, and more particularly, to an air-cooled condenser system having a multi-function condensate manifold.
  • the steam condensation system extracts heat from steam to provide resultant condensate, such as for reuse in an industrial process.
  • an air-cooled condenser provides for a cool ambient air flow to allow for thermal transfer of heat from hot steam.
  • the steam is condensed and the condensed liquid, such as water, collected.
  • the condensed liquid can be reused or returned to a source.
  • An exemplary air-cooled condenser is an A-frame condenser.
  • Hot steam is transferred to a steam distribution manifold at an upper portion of the condenser.
  • the steam distribution manifold fluidly connects with oppositely angled cooling bundles, such as finned-tube bundles, which form the shape of an A having the steam distribution manifold at the uppermost apex.
  • Cool ambient air is moved over the finned-tube bundles by a fan disposed at a lower portion of the condenser.
  • Steam is drawn from the steam distribution manifold into the tube bundles via a vacuum effect caused by the change in temperature, because the reduced temperature within the tubes will yield an increase in the steam-vapor density, until ultimately the steam undergoes a phase transformation to liquid water.
  • a support structure provides for positioning of the condenser spaced above a support foundation, to allow for flow of the air drawn into the condenser by the fan.
  • the condenser provides a closed loop system, where collected condensate in the collection manifolds is transferred to a larger storage tank, such as a boiler or intermediate storage. Non-condensable gases are removed by one or more air evacuation units fluidly connected with the finned-tube bundles and condensate collection manifolds.
  • Such an air-cooled condenser also is referred to in the industry as a dry cooling condenser because cooling liquid such as water is not contacted with the steam (i.e. 'wetting' it) to absorb its energy and condense it.
  • Dry condensers provide numerous advantages over wet cooling condensers, in which a cooling fluid such as liquid water contacts the steam to condense it, because they consume little to no additional water and therefore are more environmentally sound.
  • V-type induced-draft condensers are similar to the A-frame ones discussed above, the principal difference being that the finned-tube bundles are angled inwardly towards one another at a lower region of the bundles, rather than diverging at the lower region, and also that the cooling is induced by a fan located above the bundles rather than below or at the lower region.
  • the fan in the V-type induced draft condensers is located at an upper portion of the condenser generally adjacent to oppositely disposed steam distribution manifolds.
  • Respective finned-tube bundles angle inwards as they proceed downward, away from the steam manifolds, to respective condensate collection manifolds, which are then drained to a larger collection tank.
  • Structural support at the lower portion of the V-shape again supports the condenser above a support foundation, while providing for considerable load support due to live loads resulting from the equipment and external forces, together with the structural weight of the condenser.
  • DE 102014112707 A1 discloses a plant for the condensation of steam.
  • FR1249717A discloses a surface condenser cooled by a forced air current.
  • the steam condensation system disclosed herein provides a scalable, single, integrated condensate manifold for use in a modular air-cooled condensation unit.
  • the integrated condensate manifold combines conventional functions of lower-region structural support, multiple condensate collection manifolds and a condensate collection tank.
  • the manifold serves as a base assembly of a respective modular condensation system to which framing, finned-tube bundles and a fan support structure are attached, and also exclusively bears the weight loading of these components.
  • an integrated condensate manifold includes a longitudinally-extending body defining therein a condensate collection volume for receiving condensate from a heat exchanging tube bundle, and a condensate storage volume for receiving and storing condensate from the condensate collection volume, said condensate collection volume being disposed within said body below the condensate collection volume.
  • a pair of coupling sections are oppositely disposed relative to one another across a vertically-extending imaginary mid-plane of the longitudinally-extending body, each for fluidly coupling to a respective heat exchanging tube bundle.
  • the pair of coupling sections extend vertically from the longitudinally-extending body at opposing acute angles relative to the mid-plane, and the pair of coupling sections are fluidly coupled to the condensate collection volume.
  • the integrated condensate manifold further includes a partition separating the condensate collection area from the condensate storage area, a vertically-extending internal support wall for bearing weight loads from elements supported on the integrated condensate manifold, a first transfer tube extending between the partition and a first outlet disposed in a bottom region of the condensate storage volume, and a second transfer tube extending between the partition and a second outlet disposed in an upper region of the condensate collection volume.
  • a steam condensation unit includes a pair of heat exchanging tube bundles arranged in a V-shape, a steam distribution manifold fluidly coupled to an upper portion of at least one of the heat exchanging tube bundles for delivering steam thereto, a fan for drawing air over the pair of heat exchanging tube bundles, and an integrated condensate manifold disposed centrally relative to the pair of heat exchanging tube bundles and fluidly coupled to lower regions of both said heat exchanging tube bundles.
  • the integrated condensate manifold has a longitudinally-extending body defining therein a condensate collection volume for receiving condensate from the pair of heat exchanging tube bundles, and a condensate storage volume for receiving and storing condensate from the condensate collection volume.
  • the condensate collection volume and the condensate storage volume are separated by a partition, said condensate collection volume and said condensate storage volume being in fluid communication with one another via a first tube extending between the partition and a first outlet disposed in a lower region of the condensate storage volume, and via a second tube extending between the partition and a second outlet disposed in an upper region of the condensate collection volume.

  • the lower support structure 44 may be omitted, where the integrated condensate manifold 40 is instead mounted closer to or directly to the respective support foundation 46.
  • the illustrated system 20 includes steam condensation units 24 arranged in a 4x6 matrix configuration.
  • the integrated condensate manifolds 40 of longitudinally adjacent condensation units 24 (as shown in FIG. 2 ) are fluidly coupled together at or adjacent their ends.
  • the steam distribution manifolds 30 of longitudinally adjacent condensation units 24 are fluidly coupled together at or adjacent their ends (as shown in FIG. 2 ), and also are shared between the laterally adjacent units 24 (as shown in FIG. 1 ).

  • any number of steam condensation units 24 may be coupled to one another via any other suitable configuration.
  • any of the longitudinally adjacent condensation units 24 may have condensate manifolds 40 and/or one or more steam distribution manifolds 30 that are not fluidly coupled at or adjacent the ends, but instead are respectively fluidly separated from one another, such as via a respective plate or wall (not shown).
  • FIG. 3 a cross-sectional view of a single condensation unit 24 is depicted in detail.
