Boiler Feed Water Treatment for Industrial Boilers and
A variable frequency electronic drive is used to set feed pressure through a PID (proportional-integral-derivative) control loop. The variable speed drive acts to control rotational speed of the pump, thus controlling the flow rate. Conclusion. New Logic's VSEP system provides an alternative approach for boiler feed water treatment applications.

How Do Burner Combustion Control Systems Work? - CrossCo
Each boiler has a boiler master, which is an A/M/Bias station that handles the firing rate for that boiler. In AUTO, the boiler master receives the plant master output, biases it, and sends that % to the fuel and air flow controllers. In MANUAL, the boiler master output is adjusted by the operator.

SAMA DIAGRAMS FOR BOILER CONTROLS APPLICATION DATA
A common application in boiler control is three-element drum level control. Boiler drum level is a critical variable in the safe operation of a boiler. Low drum level risks uncovering the boiler tubes and exposing them to heat stress and damage. High drum level risks water carryover into the steam header and exposing steam turbines to corrosion
