85-11: Restoration and Repair of 30-Year Old Cooling Towers at the PaducahMajor cooling tower repairs accomplished during 1983 and 1984: 1) Replacing the underground portion of 46 risers located at 6 cooling towers, 2) Deck replacement on 2 16 cell counterflow and 2 14 cell crossflow towers. 3) Fan motor feeder cable and conduit replacement on 2 16 cell counterflow and 2 14 cell crossflow towers. Deals with equipment condition, problems encountered and types of replacement materials.

Cofimco extensive research and laboratory tests pointed out in the development of an innovative shank to connect the blade airfoils to the hub of large axial fans used on Cooling Towers and Air Cooled Condensers: the new pultruded FRP shank reinforced with carbon rovings

Better economy

with various biocides

the concentrating nature of cooling towers combined with chemical treatment programs subjects blowdown treatment systems to chemistry that may significantly influence performance

clay particles

pump upgrades and the installation of a cathodic protection system

bulk fluid velocities and fluid chemistry typically help to determine the lifetime of wetted surfaces

loads that vary with ambient temperature

This paper presents results of an in depth laboratory and on-site study investigating the use of tertiary treated municipal effluent as cooling water make-up

Comparison of CFD simulation with program code also shows a good match with design data

The motors are located in the center of the fan hub where there is typically only a nominal amount of air movement

the choice of best product for th application becomes more critical
