13-15: Experimental Characterization of Wind Effect on Natural Draft Cooling Materials

13-15: Experimental Characterization of Wind Effect on Natural Draft Cooling MaterialsWind curves provided by manufacturers to describe the impact of wind on the cold water temperature of EDFs natural draft cooling towers remain theoretical and probably include margins. Thus, it is of EDF interest to characterize the real effect of wind on its cooling towers. The paper will shortly describe EDFs performance e monitoring tool and explain how it can be used to build experimental wind curves. Then, examples will illustrate the way these

operating conditions

Simultaneous with this concern about thermal pollution and the trend towards use of recirculatory systems incorporating evaporative cooling systems

Concern about aquatic toxicity of cooling water discharges has driven the development of biodegradable inhibitors for use in cooling water treatment

“traditional” chemicals or treatments may be “greener” than conventionally imagined or portrayed

water conservation)

Soft water corrosion problems are increasing due to the use of non-chemical pretreatment systems

Comparisons between laboratory and field data are discussed

This recent testing program provides a today's performance perspective of the most commonly used fills of this type

while vibration instruments detect motion in solid objects

Within the next few years this gap should be closed by CTI and ASME

Microbiological control in recirculating systems should be considered equally
