16-29: Comparison Of Fouling Kinetics On Four Different Fills Operated In Cooling Tower Water Treatment Programs

16-29: Comparison Of Fouling Kinetics On Four Different Fills Operated In Cooling Tower Water Treatment ProgramsEDF operates 30 condenser open cooling circuits in its French nuclear power plants (NPP). In order to extend their lifetime, the company has to carry out major renovations of the fills located in the cooling towers, which need to be replaced after around 30 years. The choice of a fill is determined by the results of preliminary tests. The following tests are conducted on fill: mechanical strength, fire resistance, thermal performance, and evaluation

and the specifications for traditional lightning protection systems installed on water-cooling towers

and formation of horrendous amounts of foam until it was found that these troubles could be minimized by pre-treatment with lime

The size of the test cells

cycles of concentration

Air-Cooled Condensers (ACCs) offer a way to significantly reduce U

Unique designs will be discussed including: low noise applications

These two groups of components require the most attention because they will deteriorate rapidly if preventive measures are not taken

The impending large increase in the construction and use of cooling towers in response to the new EPA requirements for thermal pollution control

Pros and cons of this approach will be discussed
