Padeepz E-Learning Materials CY8151 Engineering Chemistry we have provided the sample materials in this page. If you like the sample and want to buy the full subject the procedure is also provided in the Video.

Boiler Feed Water


The water fed into the boiler for the production of steam is called boiler feed water


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

  1. Formation of deposits in steam boilers and heat exchangers (scale and sludge)
  2. Priming and foaming ( carry over )
  3. Caustic embrittlement
  4. Boiler corrosion

Hi is a place where we make Engineering Students to understand their subjects in an easy and in a effective way. Which leads to greater knowledge in the subject and Provide plenty of time spending in innovative ideas.
