    Jul 26, 2016 · In high voltage boilers, scale tends to originate first at the ends of the spray nozzles. The nozzles are designed to shape the stream of water that flows onto the electrodes. If the scale deposits are severe enough, the water stream loses its design definition, which often leads to arc-overs. Under this condition, the boiler goes off-line.Learn More

  • What is a Boiler and How Does it Work? | RealPars

    Aug 19, 2019 · Once again, when the water is boiled, steam is generated and moved downstream. A water-tube boiler is more thermally efficient than a fire-tube boiler, but they are more complex to construct and the quality of the water can be a limiting factor. The water may need filtering to operate most effectively.Learn More

  • Water Handbook - Steam Purity | SUEZ

    In the modern water-tube boiler, separation of the steam-water mixture entering a relatively small steam drum is a complex process. For every pound of steam generated, as many as 15-20 lb of water may circulate through a drum. As a result, 99.97% or more of the circulating water must be removed from steam to ensure the desired steam purity.Learn More
