86-05: The Selection and Testing of Plastics Tower Fill Natural Draft Towers

86-05: The Selection and Testing of Plastics Tower Fill Natural Draft TowersA field and laboratory testing program was conducted to measure the temperature off installed tower fill and identify a cost effective fill to refurbish existing towers. The creep rate of PVC fill was determined as a function of temperature, load and sheet thickness.

Procedures have been developed for the successful evaluation of four water treatment biocides versus the acid-producing bacteria Thiobacillus novellas and the iron oxidizing bacteria Leptotrhix discophoro

with an evaluation of the components and thermal potential the user can establish the necessary steps to meet his cooling requirements

natural-draft cooling can sustain significant deterioration

being called into question

Mast Climbing Work Platforms (MCWP’s) are becoming a popular method of access in the demolition and repair of cooling towers and stacks throughout the USA

Surface analysis was used to identify passivation films and correlate their chemical composition to respective treatment and water conditions

The differences between various eliminator configurations highlight the benefits of new technology and theory applied to drift eliminators to achieve the best performance and lower pressure drop

performance verification

the process of removing and replacing packing (fill) in a cooling tower involves working at height in most cases

to remove and sometimes to change fills

including the dual sources of makeup water and blowdown control
