19-05: A Fouling and Thermal Performance Test Rig for Cooling Tower FillEskom's coal fired power stations mostly have natural draft wet cooling towers, where excessive fouling results in maintenance and performance issues. Eskom is planning to replace the asbestos fill in selected cooling towers, and needs 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 fouling

Laboratory and field case studies will be discussed

NEMA motor

These two groups of components require the most attention because they will deteriorate rapidly if preventive measures are not taken

consume too much energy and/or require too much plan area

This paper aims to demonstrate a correlation between coupon level pin bearing tests and in situ laboratory testing of FRP joints commonly utilized in cooling towers and other structures designed and built with pultruded FRP structural members

In comparison to standard methods

scale inhibition is related crucially to characteristics of water flow

Some of the standards which will have their important points reviewed include: Redwood-Lumber Specifications

In many areas of the globe water has become

The paper includes 10 months of operational data from a 345-MWe power plant with NDCT

Determining the source of exposure is a key factor in determining responsibility and involves many disciplines

The models discussed are directed towards aerated cooling water systems
