How to avoid water treatment problems in your heat exchangers and contingency planning for cooling tower failure were among the highlights of the conference program presented at the Cooling Technology Institute's annual meeting.
Held Feb. 3-6 at the Wyndham Greenspoint Hotel in Houston, the CTI annual meeting included a program that delivered on its promise to provide practical solutions. In his presentation on heat exchanger designs that lead to failure, T.J. Tvelt Jr. of Puckorius & Associates Inc., Evergreen, Colo., explained that cooling tower water should be thought of as an engineering material. Left to its own devices, cooling water will corrode, and it can form mineral scale. Because it frequently contains suspended matter, Tvelt noted that it can and frequently does support micro- and macrobiological growth. Tvelt reviewed shell-side cooling in shell-and-tube heat exchangers and explained how designs must address the limitations of the cooling water.
