86-10: Identification of Cooling Tower Wood Attack and Methods of Control Thermal Performance

86-10: Identification of Cooling Tower Wood Attack and Methods of Control Thermal PerformanceBiological and chemical attack can greatly accelerate the deterioration of cooling tower wood. The damage, once inflicted, is irreversible and often results in premature and costly wood replacement. Biological attack is the more serious type of attack and is difficult to detect. Control of each type is essential for good tower maintenance. A review of wood structures, types of attack and methods for control are presented. Effects of alkaline cooling

While effective

Health concerns and aesthetic concerns impact any reuse decision

the inclusion of chromates in blowdown was recognized as objectionable not only from an ecological standpoint

This paper will discuss the use of on-line instrumentation

This Standard offers recommendations for Fire Resistant Partition Systems used in cooling towers

Liquid biocides continue to be a popular choice for control of microorganisms in industrial water systems and numerous treatment options exist in both oxidizing and non-oxidizing biocide categories

evaporative pre-cooling of the air going to the heat exchanger can be the solution

need for preservative treatment and review what is available in lumber treat­ment today

which will allow higher cycles of concentration than standard acid and non-acid cooling water programs

Evaporative pre-cooling of air cooled heat exchangers provides the thermodynamic advantages of water cooling towers with the reduced maintenance requirements of air cooled heat exchangers
