Boiler Feed Water
The water fed into the boiler for the production of steam is called boiler feed water
REQUIREMENTS
It should be free from
- Dissolved gases (O2,CO2,carbonic acid etc)
- Suspended impurities, oil and turbidity
- Dissolved salts, hardness causing substances and alkalinity
- It should be zero hardness
If the water is untreated, it leads to some troubles in the boiler
- Formation of deposits in steam boilers and heat exchangers (scale and sludge)
- Priming and foaming ( carry over )
- Caustic embrittlement
- Boiler corrosion
