WebApr 12, 2024 · High conductivity, excess boiler water alkalinity, rapid changes in demand, and high boiler water levels are common factors that can lead to impurities in the steam due to foaming and/or carryover. The boiler design can also impact the potential for carryover. WebSep 29, 2016 · The water's pH also matters. If it goes too high (alkaline) the water will foam and prime. Steam-heating boilers work best with a pH of between 7 and 9. If the pH gets to 11, the water will foam and prime like mad. The Dead Men used baking soda to lower the pH of the water and cure the foaming problem, but there are also commercial chemicals ...
WebApr 12, 2024 · The foam may be carried over with the steam, particularly when the generation of steam is at maximum, which causes boiler water (containing Sodium Hydroxide and salt) to pass out into the steam pipes. The content of Silicic Acid is important for boilers with high pressures. WebSep 14, 2024 · As the steam boiler generates steam rapidly, some water particles are carried along with the steam. The process of formation of wet steam is known as priming. Due to the carryover of water droplets in the steam, the energy efficiency of the steam is reduced. It leads to salt crystals deposition on the superheaters and turbines.
