78-10: Preservative Treatment of Cooling Tower Lumber a State-of-the-Art Report Use of Biocides

78-10: Preservative Treatment of Cooling Tower Lumber a State-of-the-Art Report Use of BiocidesPreservative treatment of cooling tower lumber has been considered a necessity for many years, but relatively few owners and specifiers of cooling towers appear to know what preservative treatment entails. More important, few seem to know what they are really getting when they specify preservative treatment in terms of actual protection against wood decay. Cooling tower failure can cost an industrial plant thousands of dollars in lost production in a

required for many client applications

The pilot is constituted of four reduced-scale open cooling circuits (around 15 thermal kW) able to mimic the thermal and chemical behavior of an industrial cooling circuit such as those found in nuclear power plants

The paper will focus on the cementations repair materials

For illustrative purposes

The tower was upgraded in April '88 during the scheduled plant outage of three weeks

Cost of cooling was found to be less than the conventional once-through system normally used

When a metal

and suspended solids

For the past several years

As the ambient temperature varies

The purpose of this paper is to show why altitude is an important factor that should be taken into consideration when designing or testing a tower

both laboratory and field data will be presented demonstrating the product's broad-spectrum efficacy
