85-20: Thermal Expansion Problems With Long Single Piece Fan Drive ShaftsThe use of larger and more efficient mechanically induced draft cooling tower fans has given rise to the use of long single piece fan gearbox input shafts. This type of shaft replaces the maintenance nuisance of intermediate shaft bearings with potential thermal expansion problems. This paper discusses some of these problems and their circumvention.

Drift eliminators and the technology behind them continue to evolve as drift specifications grow more stringent and tower operators strive for the best performing products available to the marketplace

Samples of the cooling water were collected

the high price of carbon fiber at that time precluded industrial applications

Make-up waters with elevated calcium hardness tend to increase the risk of scaling in circulating cooling systems where the concentration of calcium increases through higher Cycles of Concentration (COC)

The purpose of this document is to provide steps in preventing "white rust" through the application of appropriate water treatment programs

The velocity also has an effect on the condensate temperature

The slate gray shade typically resists color changes when exposed to UV better than other pigmentations

It was found that seawater cooling towers can satisfy the cooling needs of large-scale petrochemical development in the hot humid Gulf region

The flexible coupling has been recently introduced after completing laboratory testing

operational components

In a scenario of reducing the supply of water to industry

because water for evaporation is unavailable at the plant site in the winter
