How water behaves in hydronic systems - HPAC

2019-6-21 · Fresh water in North America typically has a pH between 6.0 and 8.5. The pH of fresh water in closed hydronic systems exhibits an interesting characteristic: independent of beginning pH, the water in properly designed, pressurized closed heating systems tends to stabilize to about eight pH. This level is acceptable for all common system metals.

What is boiler water PH? And why so maintained? -

> Natural water is usually between 6.5 and 7.5 pH. A common recommendation is to maintain boiler water at 8.5 pH.Acidic water is corrosive. Alkalinic water is more prone to scaling.Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3

The importance of pH in steam-boiler water - Heating

If the pH is lower than that, the water will start eating the pipes. If it's higher than that, the water won't corrode metal, but it may begin to foam, and that's not good. Hold that thought for a moment. You're on a job and you have a steam boiler that's taking on a lot of feed water because the system has leaks.

Corrosion in the downstream boiler equipment is mainly caused by condensed carbon dioxide. CO 2 in its liquid phase forms carbonic acid, which – by dissociation – reduces the pH value of the condensate. The result: corrosion.

Boiler water chemistry – Properties of feed water

Controlling the PH of water is the first step towards boiler treatment. We all know that if PH is below 7 the solution is acidic and above 7 it's alkaline. For boiler water PH is maintained between 11-11.8 and that of feed water between 7-9. Effects. If either of the values increases, water will accordingly become acidic or alkaline, leading

The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9. Pure water is neutral, with a pH of 7.0. When chemicals are mixed with water, the mixture can become either acidic or basic (alkaline).

Boiler Water Tests | Viking Water Technology, Inc.

pH – Boiler and Condensate. pH is a measure of the acidity or basicity (alkalinity) of water on a scale running from 0 to 14. The neutral point on this scale is pH 7; values below 7 indicate increasing acidity and those from 7 to 14 indicate increasing basicity.
