Cycles of Concentration for Boilers | by Taylor Industrial | Medium

2017/3/7 · Two weeks ago we talked about options for calculating the cycles of concentration (CoC) in cooling water systems. I promised we would follow that up with a discussion about calculating the CoC for boiler water, so let's get started. As with cooling water systems, maximizing boiler cycles means reduced fuel, water, and chemical costs.

Boiler Water Tests | Viking Water Technology, Inc.

2016/5/4 · Conductivity Test (Boiler and Condensate) Conductivity is a measure of the ability of water to conduct electric current. The ability to conduct electricity is related to the amount of dissolved (ionizable) solids in the water. Conductivity is generally read in units called micromhos, using a sample which has been neutralized with gallic acid to

2016/2/24 · For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: σ T = σ25 [1 + α (T – 25)] σT = Conductivity at temperature T (µS / cm) α = Temperature coefficient, per °C (Typically 0.02 / °C or 2%°C)
