CONVENTIONAL THERMAL DEAERATOR
TYPE:U-KD
(Thermic gas separators) For oxygen (O2) and carbon dioxide (CO2) dissolved in feed water for steam boiler destroy metal surfaces of both steam boiler and steam lines
For the removal of these corrosive gasses, feed water is atomized and heated with steam, CO, and O2 dissolve at 60 °C and 100 °C, respectively. The atomizing process is applied with sprinkling system at conventional deaerators.
Disadvantages of this system: Water level inside the deaerator should be at least 6 meters above the suction side of feed water pump to avoid evaporation and cavitation.
For this reason, height of the boiler room should be at least 10 meters.
Additionally, supporting platform for the deaerator is needed.
Thus construction cost of the boiler room increases.
