The Direct Air Cooled Condenser System (ACC) is an innovative solution for power stations facing high water consumption, particularly in areas with water shortages. The ACC system uses large axial flow fans to inhale air and skim the tube bundle from the outside, taking away heat and allowing steam to condense into water. With this system, water savings of over 85% can be achieved.
The ACC system includes a range of components, including a tube bundle, air supply and evacuation systems, a condensate system, cleaning system, exhaust steam ducting system, supporting structure, draining system, electrical system, and instrument and control system. It is designed to be flexible and adaptable to a variety of settings.
In addition to its impressive water savings, the ACC system has several other benefits. It occupies less space, has various anti-freezing methods, and has been tested extensively to ensure its performance and reliability. With its technical strength and research backing, the ACC system is an effective solution for power stations seeking to reduce water consumption.
Shuangliang Direct Air Cooled Condenser Technical Features
A key feature of the ACC system is its use of single-row tubes. These tubes are made by welding aluminium serpentine fins to large flat tubes, creating a structure that is both strong and corrosion-resistant. The single-row tubes provide excellent heat transfer performance, with high efficiency, low-pressure loss, and good cleaning ability. They also have good anti-freezing performance, allowing the ACC system to operate effectively in cold temperatures. Overall, the use of single-row tubes is a key factor in the ACC system’s ability to provide reliable, efficient, and water-saving performance.
