This is a boiler feed water treatment process that aims to remove suspended solid impurities in a boiler to enhance heat transfer efficiency. It is also a control strategy whereby it limits the amount of corrosion cau sed by these impurities. The rate of blowdown in this system helps in eliminating the levels of contamination in the boiler unit.
