  • Sulfites for Oxygen Control - National Colloid

    In modern boiler systems, dissolved oxygen is handled by first mechanically removing most of the dissolved oxygen and then chemically scavenging the remainder. The mechanical degasification is typically carried out with vacuum degasifiers that reduce oxygen levels to less than 0.5-1.0 mg/L or with deaerating heaters that reduce oxygen concentration to the range of 0.005-0.010 mg/L.

    The solubility of oxygen in water is inversely proportional to temperature. That is, the hotter the water, the less oxygen it will hold. The goal of any feedwater treatment program is to reduce the amount of oxygen in the feedwater so that as little as possible enters the boiler.

    Because the solubility of oxygen in water is very low under these conditions, 97 to 98% of the oxygen in the incoming water is released to the steam and is purged from the system by venting. Although the remaining oxygen is not soluble under equilibrium conditions, it is not readily released to the steam.

  • The Importance of Boiler Water and Steam Chemistry

    High boiler water alkalinity increases the potential for foaming, particularly in the presence of suspended matter. Where a chemical species is sufficiently volatile, it also carries over as a vapor in the steam. Total carryover is the sum of the mechanical and vaporous carryover. Vaporous carryover depends on solubility in steam and is

    Vacuum deaeration has been used successfully in water distribution systems. However, pressure deaeration (with steam as the purge gas) is normally used to prepare boiler feedwater. Steam is chosen as the purge gas for several reasons: it is readily available. it heats the water and reduces the solubility of oxygen.
