TP06-07: Evaporative Pre-Coolers for Air Cooled Heat Exchangers
Abstract: Evaporative pre-cooling of air cooled heat exchangers provides the thermodynamic advantages of water cooling towers with the reduced maintenance requirements of air cooled heat exchangers. In areas where water conservation, cooling tower plume abatement, or water discharge permits are a problem, evaporative pre-cooling of the air going to the heat exchanger can be the solution. This paper discusses the advantages of pre-coolers and presents some basic design considerations.
TP06-11: A Review of Drift Eliminator Performance
Abstract: 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. As such, the choice of best product for the application becomes more critical. One important aspect of drift performance is the pressure loss characteristic of a drift eliminator and the difference between wet and dry measurements. The differences between various eliminator configurations highlight the benefits of new technology and theory applied to drift eliminators to achieve the best performance and lower pressure drop. This yields continued improvements for the tower operator.
TP12-21 Best Practices for Minimizing Drift Loss in a Cooling Tower
Abstract: There are many factors associated with the drift loss potential of a cooling tower. With the greater restrictions on drift emissions that are now required in many locales, it is important to know all of these factors to make sure that the drift loss of a tower is minimized. This paper will explore the various factors involved for both counterflow and crossflow cooling towers.
TP17-05 A Study on Bio-Fouling Characteristics of Contemporary Trickle and Modular Splash Fills
Abstract: The development and marketing of contemporary modular trickle and splash fills has yielded a perception that any “wire frame model” type fill offers similar resistance to fouling as classic splash bar fills. However, laboratory testing and real world experiences have shown that these fills exhibit similar responses to bio-fouling problems as film fills with respect to product design and flute geometry. A systematic laboratory method of evaluating weight gain due to bio-fouling and sediment accumulation illustrates the effects that these different design elements have on the actual fouling resistance of this type of fill.
