Boiler Feed Water Pump in Power Plants| BOLLFILTER

The water supplied to the boiler which is converted into steam is called boiler feed water. The steam produced in a boiler is condensed after use and is returned to the boiler as recovered condensate and made-up with additional fresh water or makeup water. Boilers require high quality water to operate efficiently. The presence of impurities in
