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/cm 2), 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.

Boiler master control should provide two kinds of control mode, one is the common master mode and the other one is the individual boiler master mode.. 1. Common master control: When the boiler is operated in parallel with the other boiler units, this control mode must be selected. In this mode the boiler is controlled so as to maintain the common high-pressure steam header pressure.
