What is Deaerator? Deaerator is a mechanical equipment that removes dissolved gases mainly dissolved oxygen & other non-condensable gases from boiler feed water. Oxygen causes pitting type corrosion in feed water systems. The process of removing dissolved gases from water also known as mechanical Deaeration. Deaeration process of boiler feed water divided in two parts: … Read more
Oxygen Pitting Corrosion in boiler: The presence of dissolved oxygen in boiler system is responsible for pitting corrosion. Water acts as a cathode of any corrosion cell to depolarize, thereby sustaining the corrosion process. The most familiar form of oxygen attack in boilers and condensate systems is oxygen pitting. Oxygen pitting is a problem for … Read more

Natural Circulation Controlled Circulation Combined Circulation #1.Natural Circulation In Boiler: Boiler feed water which is pumped with high pressure boiler feed water pumps first reaches at economizer. Here temperature … Read more
What is Cation Conductivity? This term is generally applicable in boiler water treatment. The concept is same as Strong Acid Cation(SAC) column works in DM Plant. To measure cation conductivity water sample is passing through cation column filled with cation resin in the hydrogen (H+) form. It is also known as acid conductivity. Why It … Read more
