alkalinity in boiler water


Boiler water treatment chemicals must enhance continuous heat exchange, corrosion protection, and high quality steam production. Scaling and corrosion are the two key heads that adversely affect the boiler system efficiency. Different treatments are used to avoid scaling, corrosion, and/or foaming.

Alkalinity - Wikipedia

2019-5-14 · Alkalinity (from Arabic "al-qalī") is the capacity of water to resist changes in pH that would make the water more acidic. ( It should not be confused with basicity which is an absolute measurement on the pH scale.) Alkalinity is the strength of a buffer solution composed of weak acids and their conjugate bases.It is measured by titrating the solution with a monoprotic acid such as HCl until
