Boiler Pressure - an overview | ScienceDirect Topics

Boiler pressure is the key factor for determining the need for a condensate polishing system. With a steam generator plant with low steam pressures (below 40 kg/cm2 ), the requirement of the CPU is usually avoided. Hard scale formation and boiler metal corrosion can easily be prevented through FW treatment before sending to the boiler proper.
