TP22-26: Sizing of Plume Abatement Coils

Plume abatement coils are used to reduce/prevent visible plumes of moisture exiting a wet cooling tower fan stack. Typically, this is done by mixing in dry, heated ambient air with the moist air stream exiting the drift eliminators. The cold ambient air passes over the “airside” of the coil and is heated by transferring heat from a hot fluid source flowing on the “tube side” of the coil. The paper will present the methodology and equations required to budget size the overall plume abatement coil surface area required.
