23-03: Extended Testing on a Real World Fill Fouling Test RigEskom's coal fired power stations mostly have natural draft wet cooling towers, where excessive fouling results in maintenance and performance issues. Eskom is in the process of replacing the asbestos fill in selected cooling towers and had to evaluate potential replacement fills. A set of four test rigs have been built that simulate conditions within a natural draft wet cooling tower. Water tapped from a cooling tower is used in the test. Both the

in essence

Basic fan theory will be considered

Two different solutions are proposed and compared with standard solution and the results of comprehensive tests on a large fan are reported

but most is for once-through cooling

The process involves the unique and practical application of ultrasound and provides both planktonic and sessile biological control

such as PVC

Over the past fifteen years

Design features incorporated into the specifications for major rebuild/repack projects for crossflow and counterflow towers to facilitate cold weather operation are also reviewed

This paper will evaluate the standard and published data for small towers per ATC-128 with respect to usability for acoustical consultants

Cooling tower component manufacturers are using increasingly varied formulations of polymers in the manufacture of their products so it is prudent to analyze if current testing standards provide the complete picture of a cooling tower's susceptibility to initiating and propagating a fire event

extensive deterioration and distress has been observed in several cooling tower support structures

While factory-assembled cooling towers are compact enough to be tested and certified in environmental test chambers
