Scaling in boilers - Lenntech

This ratio depends on two factors: boiler pressure and boiler water pH. The value of the ratio increases almost logarithmically with increasing pressure and decreases with increasing pH. If the silica enters the boiler water, the usual corrective action is to increase boiler blowdown, to decrease it to acceptable levels and then to correct the

Boiler feedwater - Wikipedia

Boiler feedwater treatment. Boiler water treatment is used to control alkalinity, prevent scaling, correct pH, and to control conductivity. The boiler water needs to be alkaline and not acidic, so that it does not ruin the tubes. There can be too much conductivity in the feed water when there are too many dissolved solids.

If the ph of a boiler feed water is at a range of 8.5-9.5

So the water coming in to the boiler feed is already alkaline. When the water enters the boiler and boils, steam is released removing some water as vapor. What doesn't leave as vapor, however, are the dissolved minerals, which stay in the boiler

PDF M-101 MACH pH levels - Commercial Boilers & Water Heaters

MACH® BOILER - pH Levels The MACH® boiler utilizes an aluminum heat exchanger that requires a very specific pH range for the hydronic fluid (water - water/glycol). The pH is a measure of the acid content of the water. The MACH® boiler requires that the pH be between 6.0 and 8.5. The pH Scale ranges from 0 (acid) to 7 (neutral) to 14 (base).
