Air Cooled Condensers

Air Cooled Condensers directly condense exhaust steam from the steam turbine without water consumption. They are frequently used in electrical power plants and waste to energy plants of all sizes.

Features

An Air Cooled Condenser (ACC) is a direct dry cooling system where the steam is condensed inside air-cooled finned tubes. Since there is no intermediate surface condenser like Indirect Dry Cooling, the overall performance is better. The SPX Dry Cooling Air Cooled Condenser features long-term mechanical and thermal integrity, excellent corrosion and freeze resistance, low fan power consumption, reliable operation and low maintenance.

An Air Cooled Condenser (ACC) is made of modules arranged in parallel rows. Each module contains a number of fin tube bundles. An axial flow, forced-draft fan located in each module forces the cooling air across the heat exchange area of the fin tubes.

The typical scope for an ACC installation includes the supporting structure, the steam ducting from the steam turbine interface, auxiliaries such as the condensate and drain pumps, condensate and duct drain tanks, the air evacuation units and related piping works and instrumentation.

Benefits

The major benefits of Dry Cooling are:

  • Elimination of additional water usage from the condensing power cycle.
  • Flexibility in power plant site selection.
  • Decreased time required for plan permitting.
  • Top quality single row Condenser fin tubes.
