- In detail
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 performances is better.
The SPX 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.
The Fin Tube is the core technology of the Air Cooled Condenser.
- Single-Row Condensers (SRC®) - an elongated, flat tube with brazed aluminum fins.
- Multi-Row Galvanized (MRC) - an oval tube with hot-dip galvanized steel fins.
