W-Style ACC

W-Style ACC® is an innovative Induced Draft Air-Cooled Condenser (ACC) directly condensing the steam turbine exhaust flow. The condensate returns to the boiler without any water loss.

With its unique “W” heat exchanger structure, the amount of steel and overall height of the ACC are dramatically reduced (compared to traditional forced draft arrangements).

The shortened finned tubes lead to a reduced ACC back pressure and a smaller risk of flow accelerated corrosion. 

The W-Style ACC® has lower overall steel weight, is less wind sensitive and offers a reduced back pressure at low temperatures. 

These characteristics result in an improvement of the average annual power plant output.
