91-15: Refurbishing America's First Hyperbolic Cooling Tower Fans & Associated Equipment

91-15: Refurbishing America's First Hyperbolic Cooling Tower Fans & Associated EquipmentWhen completed in 1962, Kentucky Power Company's Big Sandy Unit 1 cooling tower was the first built in this country using large scale natural draft design with a concrete hyperbolic shell. The decision to replace the internal components recently after 26 years of operation offered the opportunity to utilize current technology and materials. This tower's maintenance and operations history, and general condition at time of rebuild will be reviewed.

and ways to avoid or minimize iron rot

This paper reports on recent developments in cleaning and passivation chemistry that are applicable to new cooling systems and to older systems requiring rust removal and passivation

These factors combine to substantially lower costs and increase applicability of ice thermal energy storage systems

Some of the difficulties and anomalies encountered when computing separate heat and mass transfer coefficients from wet cooling tower fill test data are presented

It deals with the physical and thermodynamic properties of air-water vapor mixtures

bromide-activated planktonic bacteria

creating a potentially significant Biofouling problem on heat transfer surface

NWD can be used as all wet cooling tower by using wet/dry lanes as wet sections

faster and more convenient

point sources

Several typical examples will be presented along with appropriate charts and graphs to clarify proper application

This paper reviews the major environmental regulations governing atmospheric emissions from cooling towers and examines some of the ways in which associated permit limits might influence cooling tower design and operation
