Boiler Water Treatment - ScienceDirect
2015/1/1 · This water is used as feed in the boiler water system. Even though high purity water is used, there are several possible sources of soluble and insoluble impurities such as cooling water ingress due to condenser tube leak, premature exhaustion of DM plant and condensate polishing unit (CPU), corrosion product pick up from the system, and impurity pick up during start-up.

Water Handbook - Boiler Blowdown Control | SUEZ
Control valve settings must be adjusted regularly to increase or decrease the blowdown according to control test results and to maintain close control of boiler water concentrations at all times. When continuous blowdown is used, manual blowdown is usually limited to approximately one short blow per shift to remove suspended solids which may have settled out near the manual blowdown connection.

Therefore, in this situation, one would expect the control valve to hover near the fully-closed position, allowing just enough water into the boiler to keep the steam drum water level at setpoint. If, however, there is a high demand for steam from this boiler, the rate of evaporation will be much greater.
