Boiler Feed Water Pump in Power Plants| BOLLFILTER
Boilers are used in power plants to generate steam which is in turn used to generate power. 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.

6 FAQs about [Feed water system in power plant]
What is a power plant feedwater heater?
Power plant feedwater heaters (FWHs) make the most of the heat from condensation to preheat water destined for the boiler. In doing so, they reduce the amount of fuel required to bring the water up to temperature. Unlike their haughty turbine or boiler counterparts, however, FWHs seem rather boring.
