94-01: Drift Testing - Scale Up From Test Cell To Field Acceptance TestIn 1989 Florida Power Corporation (FPC) agreed to install helper cooling towers at their Crystal River Generating Station to cool circulating water discharged to the Golf of Mexico. As a result of agreements with the environmental agencies a maximum allowable helper cooling tower drift rate of 0. 002 percent was required, including compliance field testing. An R&D drift testing program was conducted in 1990 in a cooling tower test cell to confirm that

environmental requirements

water consumption and GHG emissions each of which will be delineated

The validity of the model has been verified and fine-tuned by extensive laboratory testing

calcium sequestration

and a high fidelity computational fluid dynamics (CFD) model

is environmentally and hygienically-sound and extremely cost-effective

There has always been an interest in the possibility of preventing deposit formation without chemicals

The driving force was often “image”

lower weight and corrosion resistance

and users of cooling towers

recent environmental legislation has increased restrictions on industrial chromate discharge

One of the most difficult chemistry parameters to control in a cooling water system is Free Halogen levels
