23-03: Extended Testing on a Real World Fill Fouling Test Rig Iron Rot Attack

23-03: Extended Testing on a Real World Fill Fouling Test Rig Iron Rot AttackEskom'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
