Fan performance considerations in cooling towers
Of concern to the user of a mechanical draft cooling tower are the performance, efficiency, and structural integrity of the axial flow fan assembly which moves the air through the tower and is an integral part of the cooling process as well as a significant contributor to initial and operating costs. Continuing research in fan design has significantly improved effectiveness, with the remaining principal research objective being a cost effective optimum performance level. It has been observed that some existing axial flow fans have inherent disadvantages such as design complexity, heavy service requirements, poor aerodynamic efficiency and poor cost effectiveness. No attempt will be made to describe all the techniques in use today nor to discuss their relative merits. The following design areas as they relate to the optimum fan performance level: airfoil selection; structural integrity; material selection, and manufacturing technique are discussed.
