  • Can we run a boiler without a deaerator? - REFINERY | OIL

    Apr 20, 2020 · There are different strategies for removing oxygen from the boiler feedwater. The best one is the deaerator though. Deaerators that work well will take dissolved oxygen from around 8ppm all the way down to 7–10 ppb. We generally use chemical oxygen scavengers to go from there to nearly 0 ppb oxygen.Learn More

    Sep 21, 2021 · Deaerators are often used in conjunction with steam-generating boilers for the removal of oxygen and other dissolved gases from the boiler's feedwater. Deaerators are typically designed to remove oxygen down to levels of 7 ppb by weight (0.005 cm³/L) or less, while virtually eliminating carbon dioxide.Learn More

    In addition, deaerators provide feedwater storage and proper suction conditions for boiler feedwater pumps. Pressure deaerators, or deaerating heaters, can be classified under two major categories: tray-type and spray-type (see Figure 10-3). Tray-type deaerators are also referred to as "spray-tray" type, because the water is initially Learn More
