An Approach towards Efficient Operation of Boilers

The water supplied to the boiler that is converted into steam is called feed water. The two sources of feed water are: (1) Condensate or condensed steam returned from the processes and (2) Makeup water (treated raw water) which must come from outside the boiler room and plant proc-esses. For higher boiler efficiencies, the feed water is pre-
