If ten cycles of concentration are permissible for a given boiler, then the concentration of chlorides should never exceed ten times that of the makeup water. For example, the makeup water chloride concentration is 10ppm so the boiler chloride concentration must never exceed 100ppm.

2010-2-17 · The term "cycles of concentration" is defined as the ratio of the concentration of the 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

For example, a boiler with a silica concentration of 100 parts per million (ppm) and a feedwater silica concentration of 10 ppm is considered to be carrying 10 cycles of concentration. Monitoring the ion continuously can allow better control and adjustment of the chemical feed rate to optimize the number of blowdown cycles.
