98-03: Upgrading and Repacking Two 460 MW Natural Draft Cooling TowersThis 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

These possibilities are discussed with illustrative pictures and data presented

assessing water quality and specifying the types

A simple method to direct more air flow over the motor is presented

Low Pressure Axial flow fans

Off-design performance analysis of cooling tower shows a detailed relationship of performance parameters with operating parameters

Sensitive paper has long been used to detect droplet impingement in several processes including drift measurement

in particular for power stations

or water discharge permits are a problem

atmospheric emissions from cooling towers can also be important considerations

It has been designated as the marketing agent for power from 33 multipurpose Federal dams in the region

All three units are served by cooling towers to cool and clean the inlet air to the gas turbine compressors in order to maintain maximum efficiency and capabilities of the units

Control of soft deposits in cooling systems is an important objective of water treatment programs
