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

Steam Pressure Reduction: Opportunities and Issues

Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler’s net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
