What Is The Principle Of Mechanical Deaeration (pressure Type) Of Boiler Feed Water? |
|
Answer» The pressure-type de-aerators operates by allowing steam into the FEED WATER through a pressure control valve to maintain the desired operating pressure, and hence temperature at a MINIMUM of 105 °C. The steam raises the water temperature causing the release of O2 and CO2 gases that are then vented from the system. This type can reduce the oxygen content to 0.005 mg/litre.
