Boiler Feedwater Deaeration - Convergence Training

Course Details. The steam or hot water is then used in a variety of facility processes. Boiler feedwater often contains dissolved oxygen, which is a common cause of corrosion inside boilers. The dissolved oxygen reacts with the boiler's waterside metal surfaces to damage boiler tubes, headers, and drums.

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

Deaerator - Wikipedia

In the Boiler deaerator Working Principle Water is heated close to saturation temperature with a minimum pressure drop and minimum vent. This ensures the best thermal operating efficiency. Deaeration is done by spraying the boiler feed water over multiple layers of trays designed to provide large contact area of the liquid surface to Pegging steam.

Vacuum deaerators remove oxygen less efficiently than pressure units. A typical vacuum deaerator is shown in Figure 10-7. Important Considerations. Inlet water to the deaerators should be largely free from suspended solids, which can clog spray valves and ports of the inlet distributor and the deaerator trays.
