Tray Deaerator vs Spray Deaerators. It is still necessary to provide a large water surface are~ so as to give adequate opportunity for the release of the dissolved gases. This is accomplished by the water cascading from one tray tier to another, exposing as much surface as possible to the scrubbing action of the steam.
eliminated. Water delivered to the boiler is pre-heated. Deaerators are designed to operate on steam from the boiler, exhaust steam, or both. If exhaust steam is currently going to waste, it may be used in the deaerator — reducing the fuel expense of the plant approximately 1% for each 10 °F rise in boiler feedwater temperature. NOTE:
