88-06: Composite Driveshafts in Cooling TowersThe use of fiber reinforced epoxy driveshafts dates back to 1969. However, the high price of carbon fiber at that time precluded industrial applications. Today, after 18 years of intense development and production, the price of carbon fiber permits competitive pricing for driveshafts of composite materials. The paper presents the whys and wherefores of composite materials applied to cooling tower driveshafts. Also presented is the status of composite

high pumping costs and environmental regulations are driving cooling water systems towards higher cycles

The switches are not even close

Subjects covered include: proper use of historical operating and performance data

evaluation of proposals and selection of vendor

Lab data will be presented

In order to extend their lifetime

Polarization and electrochemical noise experiments

thereby differentiating this technique for its waste minimization value

specialist contractors are finding the equipment invaluable

The cooling towers are installed as helper cooling towers

water quality analyses and data management methods to document the historical operation

The data presented includes some little-known work on in-situ pitting corrosion measurements featuring proton-induced characteristic x-ray emission and D
