calculation of feed water for 10 ton capacity steam boiler

Practical considerations for modern BFW pumps

Boiler feed water. Boiler feed water is used to supply ("feed") a boiler to generate steam. The BFW is usually stored, preheated and conditioned in a feed water tank and supplied to the boiler by a boiler feed-water pump system. Corrosive compounds, especially oxygen and carbon dioxide, need to be removed, usually via a deaerator.
