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.
Product Detail (max 5000 characters)*
Traditional A-Frame, is the state-of-the-art Air Cooled Condenser (ACC), suitable for small to large power plants in a large variety of site conditions (low ambient temperature, high wind, high seism, low noise…).
The heat exchanger’s finned tube, the core technology of the Air Cooled Condenser, is the Single-Row Condenser (SRC®) tube – an elongated aluminum cladded carbon steel flat tube with brazed aluminum fins.
The excellent corrosion and freeze resistant SRC® finned tubes are manufactured in the SPX Dry Cooling fully owned state of the art factories.
Heat exchangers are supported by an A-Frame structure, which can be mounted on concrete or steel structure. Both primary and secondary type heat exchangers are provided to ensure good non-condensable gas extraction to the air evacuation unit.
Airflow is delivered by forced draft axial fans, driven by electric motors and gearboxes, installed below the heat exchangers.
The typical scope for an ACC installation includes the heat exchangers, the fan motor groups, the supporting structure, the steam ducting from the steam turbine interface, auxiliaries such as the condensate and drain pumps, condensate tank, the air evacuation units and related piping works, electrical and instrumentation. With over 200 SRC ACC installations, SPX Dry Cooling has extensive experience in designing, manufacturing, delivering and constructing A-Frame ACC’s all over the world.
