  • Boiler Water Treatment Method - Amanda Water Tech Inc.

    Aug 02, 2021 · The principle is to heat the boiler feed water to the boiling point, so that the solubility of oxygen decreases, oxygen in the water constantly escapes, and then the oxygen generated on the water surface together with water vapour is removed, so that the water can be removed from the various gases (including free state of CO2, N2).Get Price
