93-03: Reduction of Noise Generation by Cooling Fans Water Reuse

93-03: Reduction of Noise Generation by Cooling Fans Water ReuseBased on an intensive research program, it has turned out that it is possible to reduce the sound power level of cooling fans with 3 to 8 dBA by the extreme application of more or less known effective principles like wider blade cord and swept leading edge line. Following international recognized measuring standards; the measuring results will be presented as well as consequences for cooling tower design and cooling fan construction.

A technical review of the fundamentals of high voltage PWT (Physical Water Treatment) systems will be presented

scale/deposit

This paper reports performance data and describes mechanisms for the following functions: 1) the control of microbial populations to very low levels

One of the main issues of condenser open recirculating cooling systems is scaling

A proper choice of the blades' mechanical and physical characteristics (stiffness and mass distribution

worker safety concerns

This paper will describe the process fordetermining the scope of the retrofits

eliminate the scheduled need for bundle cleaning

This may impair the structural integrity to withstand dynamic loading due to earthquakes

The study compares theoretically predicted values with full-scale actual laboratory test results

It will also present various material and mounting options

and information technologies — will be used to illustrate how the challenges can be overcome
