What is the reason for keeping a boiler feed water pH

Chemical reactions happen very fast at elevated temperatures. Because of this we try to operate the boiler at the lowest possible corrosivity relative to pH (Note: this is only for boiler operating without high purity feedwater). That point is aro

Boiler Pressure - an overview | ScienceDirect Topics

Boiler pressure is the key factor for determining the requirement of a CPU system (see Figure II/3.6.6-1). For the steam generator plant with low steam pressure (below 40 kg/cm 2), the requirement of a condensate polishing unit is usually avoided. Hard scale formation and boiler metal corrosion can easily be prevented through feedwater

That allows more low-pressure steam to be generated in the low-pressure system, since a 0°F temperature difference between the economizer outlet temperature and the drum saturation temperature can be utilized to increase the HRSG efficiency in a cost-effective manner.
