Deaerator In Boiler Feedwater System- Boiler

Deaerator In Boiler Feedwater System. The steam vigorously scrubs the dissolved oxygen from the makeup and pumped returns. The trapped returns enter the deaerator storage section. Steam from the returns also flows upward through the deaerator trays, while the water drops to the water level in the deaerator storage section.

Deaeration Systems - P C McKenzie Company

Deaerators are used to remove oxygen from boiler feedwater. Trapped returns are piped to the deaerating section where flash steam is prefentially used for final deaeration. Since the recycle pump capacity exceeds the deaerator capacity by at least 25%, the deaerator is able to meet 0.005 cc/l, from zero to 100% load.
