Best Management Practice #10: Cooling Tower Management. Because dissolved solids enter the system in the make-up water and exit the system in the blowdown water, the cycles of concentration are also approximately equal to the ratio of volume of make-up to blowdown water.

Concentration cycles in petroleum refinery cooling towers usually range from 3 to 7. In some large power plants, the cooling tower concentration cycles may be much higher. (Note: Draw-off and blowdown are synonymous. Windage and drift are also synonymous.). Back to Chemical process engineering FAQ Index Back to Chemical process engineering Forum

boiler water to the concentration of the feedwater. Often referred to simply as “cycles,” this ratio is inversely proportional to the total blowdown rate – cycles increase as blowdown decreases, and vice versa. So, by increasing his boiler water cycles, an operating engineer will save fuel that would otherwise be lost in blowdown. When

Cooling Tower Cycles of Concentration and Efficienc

Cycles of Concentration. An important concept related to Cooling Towers is the Cycles of Concentration (also known as Cycles or Concentration Ratio). Cycles of Concentration is monitored with a conductivity meter and it is a measure of the concentration of dissolved solids in the Cooling Tower process water.

Cycles of concentration (or cycles) is a comparison of dissolved solids level of the blowdown with the feedwater. This can be expressed as: where FW stands for feedwater and BD stands for blowdown. Just like in a cooling tower system, cycles of concentration can also be expressed as: Now, if we solve for BD, we get:
