03-07: Crossflow to Counterflow Natural Draft Tower ConversionThis paper describes the turnkey conversion of an existing Marley Class 700 natural draft cooling tower at Mirant Mid Atlantic LLC's Chalk Point Generating Station in Southern Maryland, USA from a crossflow configuration to a counterflow configuration. The work involved demolition of the severely degraded crossflow cooling heat exchange system and installing an all new composite fiberglass support structure, low fouling PVC film fill, high efficient
