    Operation of the boiler with high water level will affect the steam purity and with low-low water level may result in overheating of the tubes. It is recommended that the unit be tripped when the drum water exceeds either the low-low or high water levels. 10. Verify proper operation of the gauge glass by opening the gauge glass drain.

  • Application of Phosphates in Boiler Water Treatment

    The main phosphate used to clean the boiler is trisodium phosphate, sodium hexametaphosphate, and sometimes an appropriate amount of sodium hydroxide and sodium carbonate is added, but the alkalinity can't be generally too strong.In addition, a low-foam surfactant wetting agent is appropriately added in order to increase the degreasing effect.

  • Difference between Low Pressure and High Pressure Boiler

    High-pressure boilers will heat steam above 15 psi and water at pressures that go beyond 160 psi. Temperatures in high-pressure boilers will go beyond 250 °F. Because of the elevated pressure at which these boilers operate, to ensure safety at all times it need to be observed. High-pressure boiler operators must audit safety devices, switches

Also, high-pressure steam, since it's more tightly packed, will call more water out of the boiler than low-pressure steam. This can lead to low-water problems back at the boiler.

  • Difference Between Low- and High-Pressure Boilers | Hunker

    A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
