98-03: Upgrading and Repacking Two 460 MW Natural Draft Cooling Towers SoundThis paper discusses the upgrading and repacking of two ND cooling towers at Hwange Power Station in Zimbabwe. The work involved replacing the badly blocked asbestos cement film pack with a high performance stainless steel splash trickle pack while maintaining both towers in operation. The repack not only restored tower performance, recooled temperature was approximately 18F worse than original design, but also improved recooled temperature by a
