  • Advantages of High Voltage Electrode Boilers for Hot Water

    May 13, 2021 · Electric boilers utilize the conductive and resistive properties of water to carry electric current and generate steam. An A.C. current flows from an electrode of one phase to ground using the water as a conductor. Since chemicals in the water provide conductivity, the current flow generates heat directly in the water itself. The moreLearn More

  • Electric - State Water Heaters

    History of feedwater treatment. During the early development of boilers, water treatment was not so much of an issue, as temperatures and pressures were so low that high amounts of scale and rust would not form to such a significant extent, especially if the boiler was "blown down". It was general practice to install zinc plates and/or alkaline chemicals to reduce corrosion within the boiler.Learn More

  • Steam Condensate Treatment - SUEZ Water Technologies

    When the steam loses enough heat for its temperature to go below its saturation temperature, it will revert to its liquid phase. The water formed by steam condensation is the condensate. It is typically free of dissolved solids as those do not leave the boiler when the steam is generated. Only dissolved can normally vent out with the steam.Learn More
