What is Boiler Feed-Water?
The water added to a boiler to rplave evaporation and blow-down losses is termed ‘feed water’. In may cases, stam is condensed and returned to the boiler as part of the feed-water. Whatever water is needed to supplement the condensate returned is termed ‘make-up water’. The make-up water is usually natural water either in its raw state, or treated by some process before use. Feed-water composition therefore depends on the quality of the make-up water and the amount of condensate returned to the boiler.
