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