91-04: Fail-Safe Cooling Water Operations Natural Draft TowersProper attention to cooling water systems operating and control parameters, and quick response to early warning signs of impending trouble can usually prevent sudden or unexpected problems. Cooling water programs and corresponding operating parameters must be evaluated and selected carefully, based on practical systems conditions. Regular chemical testing and trending of data will highlight undesirable effects before they become serious using the

forming biofilms that inhibit heat transfer

The tests and results for the analyses are discussed

This specification offers recommendations for classification

the pH level is maintained while biological fouling/scale deposition are greatly reduced or eliminated

Although the thermal performances of natural draft cooling towers occasionally fail to meet expectations

The paper includes a discussion on development of the molybdate-diol organic program and includes case history examples of application of these programs

and also on an American Standard Association committee on the subject of fire protection for water cooling towers

Each solution will restrain the pressure thrust forces

The strategies presented will cover basic operational methods

The report also presents and summarizes a critique of objections to the ASHRAE research project

concern was expressed about the possible detrimental effects of releasing large quantities of heat and water vapor into the atmosphere from concentrated
