Boiler Feedwater Treatment (Part I): Why Water Treatment is

Boiler feedwater. Boiler ‘feedwater’ is the water supplied to the boiler. Often, steam is condensed and returned to the boiler as part of the feedwater. The water needed to supplement the returned condensate is termed ‘make-up water’. Make-up water is usually filtered and treated before use.


Failure of boiler tubes by S- and V- induced hot corrosion has been quite a common phenomenon in boilers burning heavy oil like Bunker C. The phenomenon is usually noted on fire side of boiler tubes.

Alfa Laval - MED - Multi-effect desalination

They also provide a comprehensive engineering best practice guide covering all aspects of steam and condensate systems; from the boiler house and steam distribution system up to the point of use; through the condensate recovery system and returning to the boiler.

Boiler feedwater

Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank.
