Windscreens improve performance, reduce O&M cost of air-cooled condensers

Air-cooled condensers depend on steady air flow created by a properly designed system of axial-flow fans, normally elevated significantly above grade. Induced by the fans, ambient air then flows vertically through the tube bundles above, condensing the steam within those tubes. During high winds, the condenser outer shell (wind wall) deflects the ambient air, producing […]
