Guide to Managing the Condensate for Condensing

The condensate expelled from a condensing water heater is acidic with a pH of between 2 and 4, so it is critical that the appropriate materials are used in all piping where this liquid is present. In high temperature areas, like the flue, stainless steel must be used to prevent corrosion.

pH | Lovibond

pH The pH scale measures the degree to which a liquid is either acidic or alkaline. A pH value of 7 is considered neutral while a pH of 1 is highly acidic and a pH of 14 is highly alkaline. The measurement of pH is one of the most frequently performed water quality determinations. Many chemical processes and operations depend on the careful measurement and control of pH.

Boiler Water Treatment Part 2 – Internal Treatment

2018-1-2 · Generally it is desirable to have a slightly high pH for boiler feed water. Ideally the feed water should be in the range of pH 8.5 – 9.5. This ensures that free carbon dioxide within the system becomes 'fixed'. If copper fed lines or heaters are used, restrict the feed water pH to a maximum of

3 Ways to Measure the pH of Water - wikiHow

2020-11-18 · pH paper will tell you the actual pH value of the water, but litmus strips typically only indicate whether the water is basic or acidic. pH strips contain a series of indicator bars that will all change color after exposure to a solution. The strength of the acids and bases on each bar differs.

Water for the Boiler | Spirax Sarco

If the pH value of the water is too low, the acidic solution will attack metal surfaces. If the pH value is too high, and the water is alkaline, other problems such as foaming may occur. Caustic embrittlement or caustic cracking must also be prevented in order to avoid metal failure.
