TP95-13: NPF Cooling Tower Fill: Its Development & Demonstration

The use of plastic packings in natural draught cooling towers significantly improves their performance. A reduction in the recool temperature of the water sent back to the condenser of 2 to 3K can be achieved compared to typical wooden splash packings. However, an unfortunate side effect is that plastic packings suffer from the build up of surface fouling in service. This has been found to have the effect of reducing the performance of the packing.
