Deaerator
IN
210MW thermal power plant deaerator situated 22mt from ground level. it consist
FST and domed vessel .
The main function of deaerator is used
to remove some dissolve gasses like oxygen, Co2 , Nitrogen etc.
Working-
When water enter into deaerator inlet valve
hence, water flows from upper surface to
lower surface at that time water is boiled and its temperature
increases which convert into steam hence temperature increases with
increase in surface area and also increased in solubility of water .as the
steam contain some dissolve gases due do
density difference dissolve gases move toward atmosphere through air vent .This
is the working of deaerator.
